dcatap namespace in WDQS
by Stas Malyshev 15 Aug '19

15 Aug '19

Hi! As part of our Wikidata Query Service setup, we maintain the namespace serving DCAT-AP (DCAT Application Profile) data[1]. (If you don't know what I'm talking about you can safely ignore the rest of the message). Recent check showed that this namespace is virtually unused - over the last two months, only 3 query per month were served from that namespace, and all of them coming from WMF servers (not sure whether it's a tool or somebody querying manually, did not dig further). So I wonder if it makes sense to continue maintaining this namespace? While it does not require very significant effort - it's mostly automated - it does need occasional attention when maintenance is performed, and some scripts and configurations become slightly more complex because of it. No big deal if somebody is using it, that's what the service is for, but if it is completely unused, no point is spending even minimal effort on it, at least on main production servers (of course, it'd be possible to set up a simple SPARQL server in labs with the same data). In any case, RDF dcatap data will be available in https://dumps.wikimedia.org/wikidatawiki/entities/dcatap.rdf, no change is planned there, but if the namespace is phased out, the data could no longer be queried using WDQS. One could still download it and, since it's a very small dataset, use any tool that can read RDF to parse it and work with it. I'd like to hear from anybody interested in this whether they are using this namespace or plan to use it and what for. Please either answer here or even better in the task[2] on Phabricator.

[GlobalFactSync] User Script, Data Browser, Reference web service - WMF Grant project
by Sebastian Hellmann 15 Aug '19

15 Aug '19

Dear all, we would like to share consolidated updates for the GlobalFactSync (GFS) project with you (copied from https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/GlobalFactSyncRE/News) We polished everything for our presentation at Wikimania tomorrow: https://wikimania.wikimedia.org/wiki/2019:Technology_outreach_%26_innovatio… All feedback welcome! -- Sebastian (with the team: Tina, Włodzimierz, Krzysztof, Johannes and Marvin) User Script, Data Browser, Reference web service (15. August 2019) After the Kick-Off note end of July <https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/GlobalFactSyncRE/New…>, which described our first edit and the concept better, we shaped the technical microservices and data into more concise tools that are easier to use and demo during our Wikimania presentation <https://wikimania.wikimedia.org/wiki/2019:Technology_outreach_%26_innovatio…>: 1. User Script <https://en.wikipedia.org/wiki/User_scripts> available at User:JohannesFre/global.js <https://meta.wikimedia.org/wiki/User:JohannesFre/global.js> shows links from each article and Wikidata to the Data Browser and Reference Web Service <https://meta.wikimedia.org/wiki/User:JohannesFre/global.js> 1. User Script Linking to the GFS Data Browser 2. GFS Data Browser <https://global.dbpedia.org/> Github <https://github.com/dbpedia/gfs> now accepts any URI in subject from Wikipedia, DBpedia or Wikidata, see the Boys Don't Cry example from Kick-Off Note <https://global.dbpedia.org/?s=https%3A%2F%2Fglobal.dbpedia.org%2Fid%2F2nrbo…>, Berlin/Geo-coords lat <https://global.dbpedia.org/?s=https%3A%2F%2Fglobal.dbpedia.org%2Fid%2F4pafr…> long <https://global.dbpedia.org/?s=https%3A%2F%2Fglobal.dbpedia.org%2Fid%2F4pafr…>, Albert Einstein's Religion <https://global.dbpedia.org/?s=https%3A%2F%2Fglobal.dbpedia.org%2Fid%2F55LmB…>. *Not Live yet, edits/fixes are not reflected* 3. Reference Web Service (Albert Einstein: http://dbpedia.informatik.uni-leipzig.de:8111/infobox/references?article=ht…) extracts (1) all references from a Wikipedia page, (2) matched to the infobox parameter and (3) also extracts the fact from it. The service will remain stable, so you can use it. Furthermore, we are designing a friendly fork of HarvestTemplates <https://github.com/Pascalco/harvesttemplates> to effectively import all that data into Wikidata. Kick-off note (25. Juli 2019) *GlobalFactSync - Synchronizing Wikidata and Wikipedia's infoboxes* How is data edited in Wikipedia/Wikidata? Where does it come from? And how can we synchronize it globally? The GlobalFactSync <https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/GlobalFactSyncRE> (GFS) Project — funded by the Wikimedia Foundation — started in June 2019 and has two goals: * Answer the above-mentioned three questions. * Build an information system to synchronize facts between all Wikipedia language-editions and Wikidata. Now we are seven weeks into the project (10+ more months to go) and we are releasing our first prototypes to gather feedback. /How – Synchronization vs Consensus/ We follow an absolute *Human(s)-in-the-loop* approach when we talk about synchronization. The final decision whether to synchronize a value or not should rest with a human editor who understands consensus and the implications. There will be no automatic imports. Our focus is to drastically reduce the time to research all references for individual facts. A trivial example is the release date of the single “Boys Don’t Cry” (March 16th, 1989) in the English <https://en.wikipedia.org/wiki/Boys_Don%27t_Cry_(Moulin_Rouge_song)>, Japanese <https://ja.wikipedia.org/wiki/%E6%B6%99%E3%82%92%E3%81%BF%E3%81%9B%E3%81%AA…'t_Cry%E3%80%9C>, and French <https://fr.wikipedia.org/wiki/Namida_wo_Misenaide_(Boys_Don%27t_Cry)> Wikipedia, Wikidata <https://www.wikidata.org/wiki/Q3020026#P577> and finally in the external open database MusicBrainz <https://musicbrainz.org/artist/e57182dc-2693-46fc-a739-a81c734a4326>. A human editor might need 15-30 minutes finding and opening all different sources, while our current prototype can spot differences and display them in 5 seconds. We already had our first successful edit where a Wikipedia editor fixed the discrepancy with our prototype: “I’ve updated Wikidata so that all five sources are in agreement.” We are now working on the following tasks: * Scaling the system to all infoboxes, Wikidata and selected external databases (see below on the difficulties there) * Making the system: o “live” without stale information o “reliable” with less technical errors when extracting and indexing data o “better referenced” by not only synchronizing facts but also references /Contributions and Feedback/ To ensure that GlobalFactSync will serve and help the Wikiverse we encourage everyone to try our data and micro-services and leave us some feedback, either on our Meta-Wiki page <https://meta.wikimedia.org/wiki/Grants_talk:Project/DBpedia/GlobalFactSyncRE> or via gfs(a)infai.org <mailto:gfs@infai.org>. In the following 10+ months, we intend to improve and build upon these initial results. At the same time, these microservices are available to every developer to exploit it and hack useful applications. The most promising contributions will be rewarded and receive the book “Engineering Agile Big-Data Systems”. Please post feedback or any tool or GUI here. In case you need changes to be made to the API, please let us know, too. For the ambitious future developers among you, we have some budget left that we will dedicate to an internship. In order to apply, just mention it in your feedback post. Finally, to talk to us and other GlobalfactSync-Users you may want to visit WikidataCon and Wikimania, where we will present the latest developments and the progress of our project. /Data, APIs & Microservices (Technical prototypes)/ Data Processing and Infobox Extraction: For GlobalFactSync we use data from Wikipedia infoboxes of different languages, as well as Wikidata, and DBpedia and fuse them to receive one big, consolidated dataset – a PreFusion dataset <https://databus.dbpedia.org/dbpedia/prefusion> (in JSON-LD). More information on the fusion process, which is the engine behind GFS, can be found in the FlexiFusion paper <https://svn.aksw.org/papers/2019/ISWC_FlexiFusion/public.pdf>. One of our next steps is to integrate MusicBrainz into this process as an external dataset. We hope to implement even more such external datasets to increase the amount of available information and references. *First microservices:* We deployed a set of microservices to show the current state of our toolchain. * [Initial User Interface] The GFS Data Browser is our GlobalFactSync UI prototype (available at http://global.dbpedia.org) which shows all extracted information available for one entity for different sources. It can be used to analyze the factual consensus between different Wikipedia articles for the same thing. Example: Look at the variety of population counts for Grimma <https://global.dbpedia.org/?s=https%3A%2F%2Fglobal.dbpedia.org%2Fid%2F9QwA&…>. * [PreFusion JSON API] While the UI allows simple, fast and easy browsing for one entity at a time, we also provide raw access to the underlying data (PreFusion dump). The query UI (http://global.dbpedia.org:8990 (user: read, pw: gfs) can be utilized to run simple analytical queries. Thus, we can determine the number of locations having at least one population value <http://global.dbpedia.org:8990/db/prefusion/provenance?query=%7B%0D%0A++++%…> (1,194,007) but can also focus on examples with data quality problems (e.g. one of the 4,268 locations with more than 10 population values <http://global.dbpedia.org:8990/db/prefusion/provenance?query=%7B%0D%0A++++%…>). Moreover, documentation about the PreFusion dataset and the download link for the data are available on the Databus website <https://databus.dbpedia.org/dbpedia/prefusion>. * [Reference Data Download] We ran the Reference Extraction Service over 10 Wikipedia languages. Download dumps here <http://dbpedia.informatik.uni-leipzig.de/repo/lewoniewski/gfs/infobox-refs/…>. * [Reference Extraction Service] Good references are crucial for an import of facts from Wikipedia to Wikidata. We are currently working with colleagues from Poznań University of Economics and Business on reference extraction for facts from Wikipedia. A current development reference extraction microservice <http://dbpedia.informatik.uni-leipzig.de:8111/infobox/references?article=ht…> shows all references and the location where they were spotted in the Infobox – ad hoc – for a given article: http://dbpedia.informatik.uni-leipzig.de:8111/infobox/references?article=ht… ( ‘&format=tsv’ also available) * [Infobox Extraction Service] A similar ad hoc extraction of factual information from infoboxes and other Wikipedia article information is available here. This microservice displays information which can be extracted with the help of DBpedia mappings from an infobox e.g. from the German Facebook Wikipedia article: http://dbpedia.informatik.uni-leipzig.de:9998/server/extraction/en/extract?…. See here for more options: http://dbpedia.informatik.uni-leipzig.de:9999/server/extraction/. * [ID service] Last but not least, we offer the Global ID Resolution Service <https://global.dbpedia.org/same-thing/lookup/?uri=http://dbpedia.org/resour…>. It ties together all available identifiers for one thing (i.e. at the moment all DBpedia/Wikipedia and Wikidata identifiers – MusicBrainz coming soon…) and shows their stable DBpedia Global ID. /Finding sync targets/ In order to test out our algorithms, we started by looking at various groups of subjects, our so-called sync targets. Based on the different subjects a set of problems were identified with varying layers of complexity: * identity check/check for ambiguity — Are we talking about the same entity? * fixed vs. varying property — Some properties vary depending on nationality (e.g., release dates), or point in time (e.g., population count). * reference — Depending on the entity’s identity check and the property’s fixed or varying state the reference might vary. Also, for some targets, no query-able online reference might be available. * normalization/conversion of values — Depending on language/nationality of the article properties can have varying units (e.g., currency, metric vs imperial system). The check for ambiguity is the most crucial step to ensure that the infoboxes that are being compared do refer to the same entity. We found, instances where the Wikipedia page and the infobox shown on that page were presenting information about different subjects (e.g., see here <https://en.wikipedia.org/wiki/Boys_Don%27t_Cry_(Moulin_Rouge_song)>). /Examples/ As a good sync target to start with the group ‘NBA players’ was identified. There are no ambiguity issues, it is a clearly defined group of persons, and the amount of varying properties is very limited. Information seems to be derived from mainly two web sites (nba.com and basketball-reference.com) and normalization is only a minor issue. ‘Video games’ also proved to be an easy sync target, with the main problem being varying properties such as different release dates for different platforms (Microsoft Windows, Linux, MacOS X, XBox) and different regions (NA vs EU). More difficult topics, such as ‘cars’, ’music albums’, and ‘music singles’ showed more potential for ambiguity as well as property variability. A major concern we found was Wikipedia pages that contain multiple infoboxes (often seen for pages referring to a certain type of car, such as this one <https://en.wikipedia.org/wiki/Volkswagen_Polo>). Reference and fact extraction can be done for each infobox, but currently, we run into trouble once we fuse this data. Further information about sync targets and their challenges can be found on our Meta-Wiki discussion page <https://meta.wikimedia.org/wiki/Grants_talk:Project/DBpedia/GlobalFactSyncR…>, where Wikipedians that deal with infoboxes on a regular basis can also share their insights on the matter. Some issues were also found regarding the mapping of properties. In order to make GlobalFactSync as applicable as possible, we rely on the DBpedia community to help us improve the mappings. If you are interested in participating, we will connect with you at http://mappings.dbpedia.org and in the DBpedia forum <https://forum.dbpedia.org/>. Bottomline – We value your feedback!

Dear Ms., I thank you for your answer. Wikidata is organized in RDF Format. However, what Mr. Bob DuCharme has just said is that there is a lack of organization of the information provided by Wikidata. In fact, several Wikidata items and statements are missing or not absolutely accurate.

I gathered this understanding from Bob DuCharme’s blog post about extracting RDF models from Wikidata with SPARQL queries: http://www.bobdc.com/blog/extracting-rdf-data-models-fro/ Marijane White, M.S.L.I.S.
