FindingGLAMs is a project by Wikimedia Sverige in collaboration with UNESCO and the Wikimedia Foundation, with the goal of collecting data on the world’s GLAM institutions and sharing it on Wikidata – a work that is sorely needed in many regions where such registers are out of date, incomplete or inexistent. At the time of WikidataCon we’ll be nearing the final stage of the project, which will give us a fitting opportunity to evaluate our work and share our experiences. We will describe how we went about collecting data from different countries, engaging the international community to help find and share datasets from their regions. In order to fill in the gaps in existing datasets, we crowdsourced additional data from GLAM professionals, using beginner-friendly tools to get more beginners to contribute. We will also highlight how we used Wikimania as a unique opportunity to gather GLAM experts from all around the world to come closer to our goal. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/All_the_world%E2%80%99s_GLAM_institutions_%E2%80%93_and_how_we_tried_to_find_them

Chemistry has long been an important domain-specific corner in the Wikipedia and Wikidata communities. The two are not tightly linked, though increasingly information from Wikidata shows up on Wikipedia ChemBoxes. We have been using Wikidata content in our research into human metabolism and metabolic diseases. This requires the information about metabolites in Wikidata to be accurate. We have been using cheminformatics to support our manual work to add missing information and compounds and curate existing knowledge. In this presentation it will be shown how the Chemistry Development Kit (Q2383032), Bioclipse (Q1769726), and QuickStatements (Q20084080) have been used in the past two years for these purposes (chem-bla-ics.blogspot.com/search?q=wikidata). We will demonstrate this infrastructure of Open Source tools, and how it can be used for using the Simplified molecular input line entry specification (Q466769) and International Chemical Identifier (Q203250) information to: link out to external databases (e.g. the EPA CompTox Chemistry Dashboard (Q26998510), MassBank (Q24088019), LIPID MAPS (Q20968889), etc); add physicochemical properties; add missing InChIs and chemical formulas using the SMILES; add new compounds based on a SMILES; and, detect incorrect or inconsistent information in Wikidata items on chemical compounds. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Cheminformatics_to_improve_Wikidata_on_chemical_compounds

This Talk will give an overview of previous and ongoing work of the WkiProject Video games. We want to present some challenges which arise during the work with video game data (editions/versions, hardware, relation with other items, ...). Video games do not stand alone as objects, they refer to several other cultural artifacts, actors and subjects. This leads to several (sometimes complex) relationships with other Wikidata items or with external identifiers. Alignment activities (vocabularies, external identifiers) and potential pitfalls. Share different perspectives on video game data. Video games have become a subject of interest in research in recent years. Describe why the video game data is relevant for research projects and how it is actually used. What are the current approaches and limitations? Since there are already big databases for video games, what can Wikidata offer? about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Sum_of_All_video_games_%E2%88%92_2019_edition

This talk reports on my experience of using the Wikidata Query Service as a platform to teach non-technical audiences about knowledge representation. This training treats SPARQL as a language to be learned from example, like any human language. Part of the approach is to use pen-and-paper graphs and role-play. Another part of the approach is to deliberately avoid a lot of the technical language that we use when talking about Semantic Web and Linked Open Data. The goal is just to give people confidence to write queries about topics that interest them, and generate visualisations that will be useful in their work. A side-effect is that attendees come to appreciate the awesome and unique power of Wikidata and its query service. Wikidata is ideally suited for this kind of training, with its enormous diversity of subjects, its many languages, its many query examples and especially its colourful, interactive query interface. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Teaching_SPARQL_as_a_Foreign_Language

Das Internet der Dinge (Internet of Things) wird immer wichtiger und wird auch kurzfristig Einfluss auf unsere Privatsphäre und Sicherheit haben. Der Talk wird eine Einführung in die Problematik anhand von Beispielen geben. Dieses Jahr liegt der Schwerpunkt auf sogenannten "Constrained Devices", also Geräten die nur sehr wenig Speicher und Prozessor Leistung habe, dafür sehr wenig Strom verbrauchen. Hier wird "Moore's Law" zur Verbesserung der Embedded-Eigenschaften (Größe, Stromverbrauch) verwendet, nicht zur Leistungssteigerung [1] In der Diskussion wird sich Gelegenheit ergeben, auch eigene Anekdoten und Erfahrungen mit IoT-Geräten beizutragen.

Wikidata properties may be limited in number, but they play a significant role in describing items by multilingual contributors. It's important to understand and view how the property labels and descriptions are translated and how new aliases are added in different languages. WDProp[1] gives a granular view on the translation path[2][3] of each property. However, it important to look at these translations at coarser level. Is there any regular translation pattern? How can such translation patterns help improve translation of newly created properties and may eventually help the translation of Wikidata items? ↑ https://tools.wmflabs.org/wdprop/ ↑ Towards Understanding and Improving Multilingual Collaborative Ontology Development in Wikidata, John Samuel, Wiki Workshop 2018 (held at The Web Conference 2018), Lyon, France, 24 April 2018 http://wikiworkshop.org/2018/papers/wikiworkshop2018_paper_12.pdf ↑ Analyzing and visualizing translation patterns of Wikidata properties.

Marriage is difficult. So is building a community from scratch, specially in a context where all the other projects besides Wikipedia are not well known. How to begin? How to interact with libraries, archives, local government to release their data to Wikidata? How to organize events about Wikidata? How to not get a divorce while helping improve the best knowledge base there is?

In this session we’ll talk about the SLING project at Google. The aim of the project is to learn to read and understand Wikipedia articles in many languages in terms existing knowledge, i.e., specific entities and properties in Wikidata. A key part of the project is that we use the same representation for both knowledge and document annotation, namely frame semantics. The Sling parser can be trained to produce frame semantic representations of text directly without any explicit intervening linguistic representation. The project is a work in progress and we have built a number of the components needed, like the SLING frame store (for building and manipulating frame semantic graph structures) and the Wiki flow pipeline which can take a raw dump of Wikidata and convert this into one big frame graph loadable into memory for fast graph traversal. The SLING Python API provides easy access to all this information. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Wikidata_knowledge_base_completion_using_multilingual_Wikipedia_fact_extraction

Wikidata is now used in millions of infoboxes across the Wikimedia projects. This round table will bring together people that have been developing and implementing these infoboxes, in order to discuss their benefits and challenges, and future opportunities to improve the infoboxes and to use them across more languages and projects. The panel will be moderated by Andrew Lih, and will include: amadalvarez, who will show a collection of WD-powered infoboxes that work in cawiki since 2016 covering more than 80% of the whole cawiki. This upgraded version, made following Wiki Hackathon'18 requirement, is a multilingual solution easy to use and installation in any WP. We'll explain main features, how translation runs and reason to be used. Mike Peel, who will show the multilingual Wikidata Infobox, which covers all topics, and is used in nearly 2.5 million Commons categories, and talk about Wikidata infoboxes on the English Wikipedia Tpt Harmonia Amanda The session will include a short presentation from each panel member, followed by audience Q&A.

We will present and discuss various sources and analytical tools to access, analyze, and visualize the Wikidata related statistics. We will introduce the difference between (a) Wikidata statistics and (b) the statistics based on Wikidata re-use across the Wikimedia projects, while illustrating the contexts within each makes more sense. A special focus will be placed on the Wikidata Concepts Monitor (WDCM) system (and its derivatives) which enable our users and editors to better understand the distribution of content in Wikimedia projects. We will also touch upon the Wikidata Languages Landscape project, a set of dashboards that analyze the representation and use of languages in Wikidata. Although no formal background in statistics or programming will be necessary to follow the discussion, we will use R in the course of the session to illustrate where, what, and how can be done with our numbers. Finally, we discuss the possibilities to act upon the introduced statistics and indicators to potentially improve the existing and establish new connections among different Wikimedia communities. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Wikidata_Statistics:_What,_Where,_and_How%3F

At first glance Wikidata appears to be an excellent source of general background knowledge. It is large, contains generally high-quality information, contains a large ontology, and can be freely used. However, it ends up being difficult to use Wikidata as is, or even with minor modifications, as a knowledge base of general-purpose information. First there are factual errors in Wikidata, such as the incorrect identification of items. These are unavoidable in a large information source, but reducing their number would be useful. There are also ontological errors, including confusion between instances and subclasses. Ontological errors cause severe problems when using Wikidata as a Knowledge base as one error generally affects much information. The ontology in Wikidata is very complex and not well organized, particularly in its upper levels, where there can be several related classes, resulting in different classes being used in different areas of Wikidata. There are also multiple related properties, again with different properties being used in different areas. To exploit Wikidata information in a knowledge base, consumers need to know which class or property is used in each area, limiting general-purpose use. There is no formal meaning for Wikidata. Consumers need to guess the intent of many classes and properties from very limited descriptions. This is particularly problematic for temporal qualifiers. A stronger formal theory would be the basis for better guidance to contributors on how to enter new information in Wikidata. The constraint mechanism does help to identify several kinds of errors. However, constraints are very weak as they only point out potential problems. Some mechanism to exclude constraint violations would be useful. Further, the poor ontology organization makes it difficult to write good constraints. Constraints that are prescriptive and that can actually affect Wikidata would aid in its use as knowledge. But what is most needed to make Wikidata more useful as general information is a tightening of the ontological modelling in Wikidata, including at least a much better description of its major classes and properties and how information combines in it. Then a formal theory for Wikidata data could be developed, permitting strong tools that can find and fix errors in Wikidata and tie together information from different parts of Wikidata. Strong tools can also discover information implicit in Wikidata and make this information available for use. Hopefully, a group of Wikidata contributors will form to produce better ontological modelling in Wikidata and produce a formal theory for Wikidata. To help, the Wikidata community could set up mechanisms to encourage fixing problems in Wikidata information over just adding new information. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Barriers_to_Using_Wikidata_as_a_Knowledge_Base

Knapp 2.000 Menschen sind jährlich in Österreich von Stalking betroffen, rund 19.000 sind es in Deutschland, laut Statistik. Das Internet und der technische Fortschritt liefern den Tätern zahlreiche neue Möglichkeiten. Ein Blick über den Tellerrand lohnt sich. Stalking ist ein hoch komplexes Phänomen, das den Betroffenen großen Schaden zufügt und gleichzeitig mit rechtsstaatlichen Mitteln schwer zu bekämpfen ist. Sandra Cegla, Kriminalkommissarin a. D. und Gründerin der Sicherheitsagentur SOS-Stalking in Berlin, wird daher einen Einblick in die wichtigsten Aspekte des widerrechtlichen Nachstellens geben. Hier könnt ihr erfahren, was Stalking ist, welche Kriminalpsychologie sich dahinter verbirgt, welche Arten von Stalking, welche Gesetze und Interventionsmöglichkeiten es gibt. Im Besonderen werdet ihr natürlich erfahren, welche technischen & digitalen Hilfsmittel die Täter einsetzen, um ihre Opfer auszuspähen und sie sowie ihr Umfeld zu manipulieren. about this event: https://cfp.privacyweek.at/pw19/talk/BLBNAH/

OpenStreetMap (OSM) and Wikidata are two of the largest collaborative open data projects that contain structured data for real-world places and things. While OSM and Wikipedia are often compared with each other (for example, people say that "OSM is like Wikipedia for maps"), OSM and Wikidata are actually even more similar. Wikidata has items, properties, statements, values, and qualifiers, while OSM has similar things like nodes, ways, relations, tags, keys, and values. Furthermore, the only thing that is better than open data is linked open data and both OSM and Wikidata have tags and properties that enable linking real-world objects found in both datasets with each other, thus making both datasets more useful for data consumers. This presentation will give a short introduction to OpenStreetMap and its data model, and explain how OSM and Wikidata can link to each other and the benefits and uses of such cross-linking. In addition, we will demonstrate the use of an online machine-assisted matching tool that OSM mappers can use to add wikidata=* tags to OSM objects that correspond to Wikidata items about the same real-world place or thing. The tool's limitations will also be explained. Linking the two projects isn't without controversy: there is some distrust within the OSM community with linking to or relying on Wikidata and they use different licenses as well, which raises questions about what information from one project can be copied to the other. (OSM has a policy that Wikidata coordinates cannot be imported into OSM despite Wikidata's CC0 license.) This issue, among other problems that hinder further collaborations between the two communities, will be touched upon in the presentation.

The talk will cover how Wikidata may be associated to increasing efficiency and effectiveness of processes and workflows in GLAM-Wiki initiatives. Efficiency refers to lowering necessary resources (time, money, stress) to contribute. Effectiveness refers to increasing the social impact content contributed has. How Wikidata can be introduced in the streamline going from setting a GLAM-Wiki partnership to reverberating contributed content in Wikimedia projects will be shown. Examples from Brazilian GLAM-Wiki initiatives will be presented.

In order to properly receive donations to Wikidata the new data must be imported in as controlled and systematic manner as possible. It is important to track imports and ensure that there is as little duplication of work as possible. With these issues in mind, John Cummings and Navino Evans created the Wikidata Dataset Import pages and began using them for tracking their work importing data from UN agencies. The goal of this is to not only to track current data imports, but also be a centralised location for documentation and discussions of mass data imports past, present and future. In this session we will offer an overview of this system as it stands today, some of the imports that we have already done and the issues we face before the full potential can be realised. What will attendees take away from this session? Attendees will come away with a better understanding of the process of importing donated data to Wikidata, where to get started with their own data imports and ways in which they could help improve the process for others. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Overview_of_the_data_donation_process

Wikidata will be turning 7, yet it is still fairly young. We are merely beginning to explore its potential as a teaching and learning platform in Academia. Wikidata has the potential to not only help its users find precise and meaningful data, or explore various topics for learning purposes; but also help educate the general public about how to interpret the data they encounter, recognize knowledge gaps, sharpen the critical thinking and their understanding of how to verify data correctness or completeness. These capacities are especially important in an era where Siri, Alexa and other AI agents use Wikidata and users take their answers at face value, and represent some examples of the capacities that fall under "Data Literacy" that will be discussed in the session. This panel will focus on featuring various examples of experimenting with Wikidata in educational settings around the world, focusing on different ways of engaging students, discussing known best & worst practices and brainstorming about new and exciting ways to better incorporate WD into Academia. To achieve this goal, we have assembled a group of Wikidatans who have been experimenting with WD in Educational settings. Among the examples that will be discuss are: The first for-credit course in the world to feature Wikidata at Tel Aviv University, Israel (Shani) Wikidata Labs and Wikidata in journalism school, University of Sao Paulo, Brazil (Joao) Implementing data literacy in the curriculum and the example of the "Witchfinder General" at the University of Edinburgh (Ewan) How to use wikidata as a tool in STEM at the Habitat School, Ajman,Dubai, United Arab Emirates (Akbar Ali) Using Wikidata to Teach Semantic Modelling to Master's degree level class at the HTW Berlin in Germany (Debora) The panel will include 3 main parts: Introduction and meeting the panelists (3 min each = ~ 20 minutes) Panel discussion about questions relating issues such as format, challenges and assessment Q & A with the audience (10 min) If you are using Wikidata as a teaching or learning tool in an educational setting, or are interested in doing so, this session is for you! about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Education_panel

Each of the panel members gets 8 minutes for presenting the proposed topic. After all the talks, we have a little panel discussion with all presenters of about 15 minutes. During the panel discussion, the audience is invited to ask questions, share ideas, or connect to other initiatives. Panel members: Lucas Werkmeister (Overview of Data Quality Tools on Wikidata) Abstract: To fight vandalism, mistakes, and other data quality issues on Wikidata, a variety of tools are available. This section gives a brief overview of what is already available to users, as well as an outlook of what’s coming in the future. Jose Emilio Labra Gayo (University of Oviedo (Spain), Username: Jelabra). (Schema visualization and authoring tools) Abstract: Historically, data sharing requires data modelling, which implies data structures consensus and dissemination. The UML community has addressed this graphically with languages that rely principally in graphical representations and only secondarily on exchange formats. It focuses on a conceptual model, leaving the data binding as a matter separate from modelling. When modelling with ShEx schemas, we get a physical representation for free. This eliminates an opaque layer from the modelling pipeline, one which trivially introduced interop problems. Wikidata users need the simplest tools possible in order to create coherent and complementary schemas and disseminate these schemas to a non-expert (at least vis-a-vis schema languages) community of contributors and users. This talk focuses on existing tools for expressing graph data, in particular, graphical tools which steepen the learning curve of the user to the extent that they aren’t even aware that they are learning a new system. We will also explore how these tools can be integrated in Wikidata toolchain both for visualizing and authoring schemas. Cristina Sarasua (University of Zurich (Switzerland), Username:Criscod). Topics to be discussed: Link Quality, data quality dimensions in existing tools. Abstract: Building on prior experiences from our workshop, we would like to discuss with the community existing challenges and opportunities in the field of data quality monitoring and assurance by focusing on Wikidata’s unique characteristics: its central role in a network of knowledge bases and other peer production projects (like Wikipedia), its ability to host plural statements and illustrate the Web’s misinformation, its multilinguality, its community of humans and machines, as well as its dynamicity. Our discussion is guided by the following questions: What are suitable data quality dimensions and measures in the context of Wikidata that are not yet (fully) addressed? What are needed methods and tools for Wikidata’s editors to edit, maintain and consume data? Andra Waagmeester (Using automation pipelines to maintain quality of Wikidata content after successful integration) Abstract: In the Gene Wiki project we maintain a family of bots to synchronise public scientific databases in the life sciences on Wikidata. Using the Wikidata integrator, which is a python pipeline developed for Wikidata data ingestion, these bots continuously monitor for changes in the primary sources of the data added to Wikidata and log these changes. New updates are processed and where possible changelogs are reported back to the curator teams of the primary sources. We use an automation server called jenkins to run and maintain these processes and would like to present this sollution. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Data_quality_panel

In this session, there will be five scheduled 10-minute lightning talks followed by a brief Q&A. Evaluating the quality of linked open data in digital libraries Gustavo Candela, Pilar Escobar, Rafael C. Carrasco, Manuel Marco-Such Cultural heritage institutions have recently started to share their collections as linked open data in order to disseminate and enrich them. One of the most important goals of the culture heritage institutions is to be reused by means of the establishment of external links. In this context, data quality in terms of linked open data can be a crucial aspect to consider when selecting a repository for reuse. In this presentation, the methodology defined by previous research for the evaluation of the quality of linked open data is adapted to the specific case of libraries. The quality measures are reported in the case of four highly relevant libraries, including Wikidata as a repository for enriching their metadata. Takeaways An idea of how a culture heritage institution should publish LOD repositories and the most relevant aspects to assess a dataset from a technical data quality of view. Creating LOD for Dutch public libraries Olaf Janssen Directly inspired by a lightning talk from GLAM-Wiki 2018 (https://bit. ly/2Dtrnxc) I started a project to improve the coverage and visibility of public libraries in the Netherlands on Wikidata. Although there are a number of websites listing all these plusminus 1500 libraries, I was quite surprised to find that none of them provide both structured and openly licensed, let alone linked data, while openness should be at the the core of every library's mission. I decided to solve this problem by adding address and geo data of every public library to Wikidata, hence for the very first time creating a (5-star) linked open data set for this type of library. This enables innovative uses, such as overviews and visualisations of the Dutch public library landscape on organisational, municipal, regional, provincial and national levels. This is of interest not only to Wikipedia and LOD enthousiasts, but also to e.g. policy makers, municipalities, scientists and journalists. In addition, to enable SPARQL generated library image galleries, I have started '1Lib1Photo' (inspired by 1Lib1Ref), an initiatieve to add an openly licensed image of every Dutch public library to Wikimedia Commons. Takeaways As a beginning Wikidatian myself, I hope to show that this type of project is suitable for beginners; adding address and geo infomation to Wikidata is a simple task that any one can do and a great way to learn SPARQL. Despite the simple nature of the inputs, the outputs (maps, image galleries, tables) are very relevant, not only for adding overviews of libraries to Wikipedia, but also for parties outside the Wiki sphere. As this project was directly inspired by work done in Wales by Simon Cobb (User:Sic19), I in my turn hope to inspire others to start similar projects in other countries. How can a small research library benefit from Wikidata? Enhancing library products using Wikidata Ursula Oberst, Heleen Smits In 2018 the African Studies Centre Leiden (ASCL) has started to engage with Wikidata by uploading its African Studies Thesaurus to Wikidata and by adding Africa-related publications in the context of WikiCite. The ASCL library is well aware of the fantastic functionalities that can be realized in library catalogs with thesaurus identifiers being present in Wikidata but adjustments to the ASCL catalog itself are at present a too far-fetched goal. How else can the library benefit from Wikidata at short notice? To prepare for the WikiconNL 2019 conference, the ASCL Library compiled an experimental web dossier which combines the components of a classical ASCL web dossier with features offered by Wikidata. The web dossier focuses on Southern African women writers and their publications. Special feature is the interactive Wikidata map that provides links to the writer’s publications in the ASCL catalogue and to her English Wikipedia article. For WikidataCon 2019 the ASCL will prepare a second experimental web dossier on proverbs in African languages. The lightning talk presents the ASCL experimental web dossiers as an example for the enhancement of library products by using Wikidata. Takeaways The web dossiers are practical use cases that can be easily implemented by other libraries. The lightning talk hopes to inspire the attendees and the presenters hope to be inspired by the audience and their experience with easily realisable and practical (library) applications for Wikidata. Using Wikidata to improve spatial subject indexing in a regional bibliography Adrian Pohl The North Rhine-Westphalian Bibliography with more than 400,000 entries is one of the biggest regional bibliographies in Germany.

With almost 60 million items, Wikidata is an incredible knowledge base for human and machine systems, and a testament to the power of collaborative work. But is "the wonderful world of open data" that wonderful? Drawing on their experiences as a data researcher and former Wikimedian, Os Keyes will step through the assumptions and tensions built into the theory and practice of Wikidata. In doing so, they will highlight ways in which the structure and premise of Wikidata creates spaces for harm against marginalised populations, and risks further enabling already-damaging systems of power. Os Keyes is a researcher and writer at the University of Washington, where they study gender, infrastructure and power. Their current projects cover facial recognition, critical tactics for technology, and the consequences of classification for trans lives. Their essays have been published in Slate, Real Life, Logic, and Scientific American; their papers have appeared at CHI, CSCW and other Human-Computer Interaction conferences. They are the inaugural recipient of an Ada Lovelace Fellowship. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Keynote:_Questioning_Wikidata

People usually bring presents to the community, that can be tools, new websites or piece of software, but also various projects, drawings... This is always a great moment, full of appreciation for the community and great to discover more about the Wikidata-related tools that people use! During this demo session, the WikidataCon participants who want to present their gift will have 2min to get on stage and show their work to others. If you want to present a birthday present, please read carefully what follows! The demos will be very short, 2min per present, in order to allow everyone to participate To save time, we will show everything from the same computer. No local command line prompt, sorry. For a smooth demo, you can consider making a video out of your screen. For the same reason, your present must be listed on this page with a link to access the demo. Of course, for the sake of the surprise, you can add it last minute, but please make sure that there is a link to click on before you go on stage! Last but not least: although the birthday presents contain a lot of tools, new features, and other programmed sweets, you are very welcome to present something of another nature: a drawing, an object, a song... anything that celebrates Wikidata and its community :) about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Birthday_presents_demo

This talk will present an update on building a project on top of Wikidata, from our experience on Inventaire. Inventaire does two things regarding Wikidata: reuse its items data and extend it in a local database reusing a very similar data model. In both aspects, we regularly encounter difficulties as the community redefines some properties, or some P31 values, which may break the expectations on which external applications are built on. We would like to discuss advantages and drawbacks of considered work-arounds such as shadow items, data model bulk upgrade, different strategies to type and shape items. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Inventaire_:_What_we_learnt_from_reusing_and_extending_Wikidata_shifting_data

In 2016 the Stadtmuseum Berlin hosted a temporary exhibition entitled "Berlin – Stadt der Frauen". The exhibition comprised works by female artists, who had enjoyed prominence in the past, but had subsequently been ignored by the male-dominated academy. As a result, these artists are underrepresented in the literature and rarely mentioned in secondary sources, which presents a challenge: How does one satisfy Wikidata’s notability criteria, when little supporting documentation exists and the artist’s notability has (only) been established by a cultural heritage institution? See this exchange for an example of the problems that can arise. Objects from the exhibition were digitised under the auspices of a publicly funded programme. Data from this project has been uploaded into Wikidata as part of a test case. The presentation will detail the process and address the issues encountered, as well as make some suggestions for the future. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Reinstating_Female_Artists_to_the_Cultural_Record_via_Wikidata

The Role of Wikidata within Data Ecosystems that Extend Beyond the Realm of Wikimedia Projects In this session the four speakers will shed light on the role of Wikidata in the context of data ecosystems that serve usage scenarios that reach beyond the realm of Wikimedia projects. They will present concrete data publication projects they have been involved in and discuss how Wikidata is complementary to third party data platforms. Together, they will try to find ways to address the various challenges encountered in their respective projects and point out areas where increased coordination will be needed in the future. The examples covered pertain to topics as varied as the description of historical places, library authority files, art history, conservation data, press archives, and performing arts: Susanna Ånäs has been involved with organisations in Finland who have developed vocabularies and ontologies of places and place names, in which a special attention is paid to historical places as well as to the history of existing places. As the Finnish Names Archive decided to use Wikibase to publish their place names collection, the modelling choices made in Wikidata have served as an important reference point for Finnish GLAMs when it comes to modelling places. Mike Dickison has worked with numerous GLAM organisations throughout Aotearoa New Zealand, helping them engage with Wikimedia projects. He will report on three main projects: the National Library of NZ authority lists, the Bloomsbury South art history project with Christchurch Art Gallery, and working with the Department of Conservation to add every living member of the endangered kākāpō species to Wikidata. Joachim Neubert is running a project on Wikidata to improve the access to the content of the “20th Century Press Archive” (PM20), a large collection of folders with millions of press clippings and other material about persons, organizations, wares, events and general subjects. Founded in 1908 in Germany, the archive soon extended its coverage to newspapers all over the world. The PM20 metadata is well structured (using controlled vocabularies, such as GND), and has been released by its creator ZBW under a CC-0 licence. (WikiProject) Beat Estermann has been working towards the creation of an International Knowledge Base for the Performing Arts based on linked data technology, relying both on Wikidata and the classical linked data approach. Over the past few years, he has contributed to data publication projects related to various segments of the performing arts value network, involving production and presenting companies, archival institutions, educational and research institutions, as well as the free online encyclopedia Wikipedia (see: Building a Linked Open Data Ecosystem for the Performing Arts). about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/GLAM_panel

Project WikiLoop is an engineering effort initiated by Google engineers, based on Google's big data resources, to contribute knowledge to open knowledge ecosystems such as Wikipedia, adhering to Wikipedia community policies. Search engines have been relying on the health of the open knowledge world, most notably Wikipedia. Yet there are few established efforts to allow continuous contributions of knowledge back to the Wikimedia ecosystem. Project WikiLoop, which was initiated by a engineers at Google, aims at rethinking our efforts in making more knowledge more accessible to the open knowledge ecosystems. We generate data using our computational power to identify potential issues. We build tools, such as bots, games and webapps, to help editors address these issues. We aim to ensure that we are following community policies (such as WP:NPOV), and that we contribute transparently and unbiased. about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Project_WikiLoop

How are different emerging communities adding their knowledge to Wikidata and also leveraging this data to improve other Wikimedia projects such as creating Wikidata driven Infoboxes, using ArticlePlaceholder to create basic entries about missing topics on Wikipedia and using Listeria bot to create indexes on Wikisource? How the Indic community has been filling the existing gaps on Wikidata with the help of datathons and labelathons? What are the different editing activities that can help engage newbies to contribute to Wikidata and filling knowledge gaps at the same time? In this session, we will try to answer these questions but with your help, of course! about this event: https://www.wikidata.org/wiki/Wikidata:WikidataCon_2019/Program/Sessions/Wikidata_for_filling_knowledge_gaps_in_the_emerging_communities:_Indic_case_studies

Communication networks have become a critical infrastructure of our digital society. However, can we really trust our networks to deliver information securely? Questions and answers -- and more questions. Communication networks have become a critical infrastructure of our digital society. With the trend toward more data-centric applications (related to health, business, social networking), especially the networks to, from, and inside datacenters need to fulfill stringent security and depenability guarantees. In this talk, I will give an overview of security challenges in today's computer networks, but also discuss opportunities. about this event: https://cfp.privacyweek.at/pw19/talk/ELYCBB/
