[Wikidata-l] mapping template parameters using Wikidata?
by Amir E. Aharoni 16 Apr '15

16 Apr '15

Hi, TL;DR: Did anybody consider using Wikidata items of Wikipedia templates to store multilingual template parameters mapping? Full explanation: As in many other projects in the Wikimedia world, templates are one of the biggest challenges in developing the ContentTranslation extension. Translating a template between languages is tedious - many templates are language-specific, many others have a corresponding template, but incompatible parameters, and even if the parameters are compatible, there is usually no comfortable mapping. Some work in that direction was done in DBpedia, but AFAIK it's far from complete. In ContentTranslation we have a simplistic mechanism for mapping between template parameters in pairs of languages, with proof of concept for three templates. We can enhance it with more templates, but the question is how much can it scale. Some templates shouldn't need such mapping at all - they should pull their data from Wikidata. This is gradually being done for infoboxes in some languages, and it's great. But not all templates can be easily mapped to Wikidata data. For example - reference templates, various IPA and language templates, quotation formatting, and so on. For these, parameter mapping could be useful, but doing this for a single language pair doesn't seem robust and reminds me of the old ways in which interlanguage links were stored. So, did anybody consider using Wikidata items of templates to store multilingual template parameters mapping? -- Amir Elisha Aharoni · אָמִיר אֱלִישָׁע אַהֲרוֹנִי http://aharoni.wordpress.com ‪“We're living in pieces, I want to live in peace.” – T.

[Wikidata-l] Impossible to add interwiki links
by Romaine Wiki 02 Feb '15

02 Feb '15

Hi all, Again, for already so many times, many users have complained on nl-wiki that it is for them impossible now to add interwikilinks on Wikidata. They are sick of all the changes all the time, especially if they experience the new design as impossible to use, as it now is. They are lost with the current design and can't add new interwikilinks. That this pops-up so many times is a serious problem that needs a solution. Wikidat is not meant for techno users only, but that is how many regular users experience Wikidata. If regular users find themselves impossible to add/update pages, the software needs a big change to re-enable them to work with Wikidata again. Ow, I am just the messenger...

28 Jan '15

OPENSYM 2015, THE 11TH INTERNATIONAL SYMPOSIUM ON OPEN COLLABORATION August 19-21, 2015 | San Francisco, California, U.S.A. http://opensym.org/os2015 | ACM SIWEB and ACM SIGSOFT supported ABOUT THE CONFERENCE The 11th International Symposium on Open Collaboration (OpenSym 2015) is the premier conference on open collaboration research and practice, including free/libre/open source software, open data, IT-driven open innovation research, wikis and related open collaborative media, and Wikipedia and related Wikimedia projects. OpenSym brings together the different strands of open collaboration research and practice, seeking to create synergies and inspire new collaborations between computer science and information systems researchers, social scientists, legal scholars, and everyone interested in understanding open collaboration and how it is changing the world. OpenSym 2015 will be held in San Francisco, California, on *August 19-21, 2015*. This is the general call for papers and includes the - research track call for submissions, - industry and community track call for submissions, and - doctoral symposium call for submissions. OpenSym is held in-cooperation with ACM SIGWEB and ACM SIGSOFT. As in previous years, the conference proceedings will be archived in the ACM digital library. RESEARCH TRACK CALL FOR SUBMISSIONS The conference provides the following peer-reviewed research tracks. - Free/libre/open source software research, chaired by Carlos Jensen of Oregon State University and Gregorio Robles of Universidad Rey Juan Carlos. This track seeks papers on all aspects of FLOSS. For detailed topics and the research track committee please see http://wp.me/Pezfy-IU. - IT-driven open innovation research, chaired by Ann Majchrzak of University of Southern California and Arvind Malhotra of University of North Carolina at Chapel Hill. This track is devoted to research on the process of expanding research and development activities beyond the boundaries of single company structures. For detailed topics and the research track committee please see http://wp.me/Pezfy-J3. Open data research, chaired by Carl Lagoze of University of Michigan. This track contributes to the increasing awareness on Open Data in research. For detailed topics and the research track committee please see http://wp.me/Pezfy-J5. - Wikis and open collaboration research, chaired by Kevin Crowston of Syracuse University. This track is dedicated to the science and application of wikis and open collaboration technology outside of the context of Wikipedia. For detailed topics and the research track committee please see http://wp.me/Pezfy-J7. - Wikipedia and related projects research, chaired by Claudia Müller-Birn of Freie Universität Berlin and Aaron Shaw of Northwestern University. This track addresses research specifically on Wikipedia and associated projects. For detailed topics and the research track committee please see http://wp.me/Pezfy-J9. Research papers present integrative reviews or original reports of substantive new work: theoretical, empirical, and/or in the design, development and/or deployment of novel concepts, systems, and mechanisms. Research papers will be reviewed by a research track program committee to meet rigorous academic standards of publication. Papers will be reviewed for relevance, conceptual quality, innovation and clarity of presentation. Authors can submit full papers (5-10 pages), short papers (2-4 pages), and research posters (1-2 pages). For more details on paper types please see http://wp.me/Pezfy-Je. Submission deadline for all research contributions is *March 29th, 2015*. Authors submit through EasyChair at https://easychair.org/conferences/?conf=opensym2015. Submissions and final contributions must follow the ACM SIG Proceedings template found at http://www.acm.org/sigs/publications/proceedings-templates. OpenSym seeks to accommodate the needs of the different research disciplines it draws on. Authors whose submissions have been accepted for presentation at the conference have a choice of having - their paper become part of the official proceedings, archived in the ACM Digital Library, or having - only a short abstract included in the proceedings (rather than the full submitted paper) in order to preserve future publication possibilities. DOCTORAL SYMPOSIUM CALL FOR SUBMISSIONS OpenSym seeks to explore the synergies between all strands of open collaboration research. Thus, we will have a doctoral symposium, in which Ph.D. students from different disciplines can present their work and receive feedback from senior faculty and their peers. Submission deadline for doctoral symposium position papers is *May 3rd, 2015*. Authors submit through EasyChair at https://easychair.org/conferences/?conf=opensym2015. Submissions and final contributions must follow the ACM SIG Proceedings template found at http://www.acm.org/sigs/publications/proceedings-templates. More information is available at http://wp.me/Pezfy-Jh. INDUSTRY AND COMMUNITY TRACK CALL FOR SUBMISSIONS OpenSym is also seeking submissions for experience reports (full and short), tutorials, workshops, panels, non-research posters, and demos. Such work accepted for presentation or performance at the conference is considered part of the industry and community track. It will be put into the proceedings in an industry and community track section; authors can opt-out of the publication, as with research papers, but will still have to provide an abstract (less than one page) for the proceedings. Submission deadline for industry and community track papers is *April 19, 2015*. Authors submit through EasyChair at https://easychair.org/conferences/?conf=opensym2015. Submissions and final contributions must follow the ACM SIG Proceedings template found at http://www.acm.org/sigs/publications/proceedings-templates. More information is available at http://wp.me/Pezfy-Jh. THE OPENSYM CONFERENCE EXPERIENCE OpenSym 2015 will be held in San Francisco, California, on August 19-21, 2015. Research, industry, and community presentations and performances will be accompanied by keynotes, invited speakers, and a social program in one of the most vibrant cities on this planet. The open space track is a key ingredient of the event that distinguishes OpenSym from other conferences. It is an integral part of the program that makes it easy to talk to other researchers and practitioners and to stretch your imagination and conversations beyond the limits of your own sub-discipline, exposing you to the full breadth of open collaboration research. The open space track is entirely participant-organized, is open for everyone, and requires no submission or review. The general chair of the conference is Dirk Riehle of Friedrich-Alexander University Erlangen-Nürnberg.

Currently you can search for simple things such as “Obama”, “Book”, etc. I plan on adding support for complex queries such as “the population of the earth” which would show the current population of the earth. In the future I also see this extension handle the submission of new entries or editing existing ones. Check it out here [1] if you’re interested.

[Wikidata-l] Question about technique used in Reasonator to populate the From Related Items section
by james＠j1w.xyz 21 Jan '15

21 Jan '15

Magnus, et al., I've been using parts of the Wikidata APIs to do the following: - Get detail about an item. For example: https://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q42&props=label… - Get items that are subclass of, instance of, or part of. For example: http://wdq.wmflabs.org/api?q=claim[279:153] Now I'd like to find out what items are related to an item through various properties, as is demonstrated in Resonator. What techniques and APIs are used? Thanks, James Weaver

[Wikidata-l] Bugs in JSON file
by Markus Krötzsch 21 Jan '15

21 Jan '15

Dear Wikidata JSON export team, There seems to be a sytnax error in the 20120112 JSON file that (I think) has already been there in the previous dump. So I guess it makes sense to report it. In line 9374899, around column 2648 of the 20120112 JSON dump, we find "snaks":[] Of course, {} would be correct here instead of []. The entity that this JSON occurs in is Q4383128. Cheers, Markus

[Wikidata-l] Freebase VIAF error rate (was next Wikidata office hour)
by Tom Morris 21 Jan '15

21 Jan '15

2015-01-17 4:27 GMT-05:00 Lydia Pintscher <lydia.pintscher(a)wikimedia.de>: > > The log is at > https://meta.wikimedia.org/wiki/IRC_office_hours/Office_hours_2015-01-16 > for anyone who couldn't make it. Denny discusses importing all missing VIAF keys from Freebase using "multichill" (unclear what that is from the context) on the assumption that the error rate is low. It would be worth checking assumptions like that with folks who are familiar with the Freebase data before acting on them. Here are some things that I think are true about the VIAF keys in Freebase: - they were assigned by a user, not by Google/Metawab (not necessarily a bad thing since some of the biggest problems in Freebase were created by G/M and some users have contributed very high quality data) - they keys were, I believe, assigned based heavily on existing Library of Congress identifiers that had previously been assigned by Metaweb. Those key assignments are not as high quality as other parts of Freebase. One easy thing to check for is people with two LC (and thus two VIAF) keys assigned. In cases where there are more than key and the extra keys don't represent pseudonyms, this is a clear error. - Freebase doesn't create separate entities for pseudonyms, unlike the library cataloging world. Depending on what decision Wikidata makes in this regard, it's something to watch out for when reusing Freebase author data (including VIAF keys) - much Freebase author data was imported from OpenLibrary which has its own set of quality issues. A bunch of this data was later deleted, leaving that portion of the graph somewhat thready and moth-eaten. It's unclear whether that was a net gain or loss in overall bibliographic data quality for Freebase. - I suspect that most VIAF keys which are in Freebase and not Wikidata represent entities which are not in Wikidata which means they aren't useful anyway since he wants to focus on creating new links, not new entities (a direction that I'm not sure I agree with, but that's a whole separate discussion). One of the key inputs to judging the quality of assertions is their provenance. Fortunately, this is recorded for all assertions in Freebase and it's possible to trace a given fact back to the user, toolchain, or process that added it to the database. Unfortunately, this information is only available through the Freebase API, not the bulk data dump. Hopefully, this will change before Google completely abandons Freebase. If any Wikidata folk want to discuss VIAF keys in Freebase (or its author data in general), feel free to get in touch. Tom

[Wikidata-l] Wikidata-Toolkit NullPointerException
by Egon Willighagen 18 Jan '15

18 Jan '15

Hi all, I have been trying today to get the Java library Wikidata-Toolkit going, but about to give up... I keep running with both 0.3.0 and current master into a NullPointerException... I thought it was how I called the code, and did add several System.out calls, and in the end just tried to get it running from the command line... I tried the example from the website (though replaced the Dump examples, which I don't see in master; btw, "mvn test" runs fine) using a pristine master: $ cd wdtk-examples/ $ mvn compile $ mvn exec:java -Dexec.mainClass="org.wikidata.wdtk.examples.EntityStatisticsProcessor" In doing so, I get the same NPE: ******************************************************************** *** Wikidata Toolkit: EntityStatisticsProcessor *** *** This program will download and process dumps from Wikidata. *** It will print progress information and some simple statistics. *** Results about property usage will be stored in a CSV file. *** See source code for further details. ******************************************************************** 2015-01-17 16:53:00 INFO - Using download directory /home/egonw/var/Projects/GitHub/Wikidata-Toolkit/wdtk-examples/dumpfiles/wikidatawiki [WARNING] java.lang.reflect.InvocationTargetException at sun.reflect.NativeMethodAccessorImpl.invoke0(Native Method) at sun.reflect.NativeMethodAccessorImpl.invoke(NativeMethodAccessorImpl.java:57) at sun.reflect.DelegatingMethodAccessorImpl.invoke(DelegatingMethodAccessorImpl.java:43) at java.lang.reflect.Method.invoke(Method.java:606) at org.codehaus.mojo.exec.ExecJavaMojo$1.run(ExecJavaMojo.java:293) at java.lang.Thread.run(Thread.java:745) Caused by: java.lang.NullPointerException at org.wikidata.wdtk.dumpfiles.DumpProcessingController.processDumpFile(DumpProcessingController.java:470) at org.wikidata.wdtk.dumpfiles.DumpProcessingController.processMostRecentDump(DumpProcessingController.java:456) at org.wikidata.wdtk.dumpfiles.DumpProcessingController.processMostRecentJsonDump(DumpProcessingController.java:426) at org.wikidata.wdtk.examples.ExampleHelpers.processEntitiesFromWikidataDump(ExampleHelpers.java:158) at org.wikidata.wdtk.examples.EntityStatisticsProcessor.main(EntityStatisticsProcessor.java:88) ... 6 more I tried finding what goes wrong, but cannot grasp all the magic that is going on... the directory it reports was created, but is empty... $ mvn --version Apache Maven 3.0.5 Maven home: /usr/share/maven Java version: 1.7.0_65, vendor: Oracle Corporation Java home: /usr/lib/jvm/java-7-openjdk-i386/jre Default locale: en_US, platform encoding: UTF-8 OS name: "linux", version: "3.16.0-4-686-pae", arch: "i386", family: "unix" Can someone give me some pointers where and how it is testing of dump files exist?
