Wikipedia Research policy
by song＠cs.umn.edu 14 Jul '23

14 Jul '23

Pursuant to prior discussions about the need for a research policy on Wikipedia, WikiProject Research is drafting a policy regarding the recruitment of Wikipedia users to participate in studies. At this time, we have a proposed policy, and an accompanying group that would facilitate recruitment of subjects in much the same way that the Bot Approvals Group approves bots. The policy proposal can be found at: http://en.wikipedia.org/wiki/Wikipedia:Research The Subject Recruitment Approvals Group mentioned in the proposal is being described at: http://en.wikipedia.org/wiki/Wikipedia:Subject_Recruitment_Approvals_Group Before we move forward with seeking approval from the Wikipedia community, we would like additional input about the proposal, and would welcome additional help improving it. Also, please consider participating in WikiProject Research at: http://en.wikipedia.org/wiki/Wikipedia:WikiProject_Research -- Bryan Song GroupLens Research University of Minnesota

Query user history edits
by Haifeng Zhang 29 Mar '19

29 Mar '19

Dear folks, Is there a good way to query a user's edit history, e.g., edit count during a period? My current solution is using usercontribs API (https://www.mediawiki.org/wiki/API:Usercontribs). But, the process has been stalled maybe due to some query limit. Thanks, Haifeng Zhang

Request for testing and feedback: Automated article section recommendations
by Diego Saez-Trumper 25 Mar '19

25 Mar '19

The Wikimedia Research team <https://www.mediawiki.org/wiki/Wikimedia_Research> is developing a new method for automatically recommending sections to add to stub articles. This method uses machine learning to suggest sections that could be added to an article, based on the sections that exist in other articles on similar topics. We think this method could be useful for helping new editors find useful onboarding tasks to do. But before we build anything, we need to test the quality of the recommendations. We are looking for experienced editors to evaluate these recommendations and provide feedback to help us improve them. We have built a testing tool <https://secrec.wmflabs.org> that makes it easy to provide quick, survey-style feedback on the quality of the recommendations, and we are also interested in more detailed feedback on the project feedback talkpage <https://meta.wikimedia.org/wiki/Research_talk:Expanding_Wikipedia_articles_…>. If you are interested in giving us feedback, please get started by reading the instructions <https://meta.wikimedia.org/wiki/Research:Expanding_Wikipedia_articles_acros…> here and then start rating articles! If you have questions about the project or more general feedback, you can reach us here <https://meta.wikimedia.org/wiki/Research_talk:Expanding_Wikipedia_articles_…>. Sincerely, Jonathan Morgan <https://en.wikipedia.org/wiki/User:Jmorgan_(WMF)> & Diego Saez-Trumper <https://en.wikipedia.org/wiki/User:Diego_(WMF)>, Wikimedia Foundation Research

please hire a CTO who wants to protect reader privacy
by James Salsman 24 Mar '19

24 Mar '19

I noticed just now that the Foundation is soliciting applications for a new CTO: https://www.linkedin.com/feed/update/urn:li:activity:6515003866130505729 Can we please hire a CTO who would prefer to protect reader privacy above the interests of any State or non-state actors, whether they have infiltrated staff, contractor, and NDA signatory ranks, and whether it interferes with reader statistics and analytics or not, please? In particular, I would like to repeat my request that we should not be logging personally identifiable information which might increase our subpoena burden or result in privacy violation incidents. Fuzzing geolocation is okay, but we should not be transmitting IP addresses into logs across even a LAN, for example, and we certainly shouldn't be purchasing hardware with backdoor coprocessors wasting electricity and exposing us to government or similar intrusions: https://lists.wikimedia.org/pipermail/analytics/2017-January/005696.html Best regards, Jim

[Wikimedia Research Showcase] March 20 at 11:30 AM PST, 18:30 UTC
by Janna Layton 21 Mar '19

21 Mar '19

Hello everyone, I'm just sending a reminder that the below Showcase will be starting in half an hour. -Janna Layton Hi all, The next Research Showcase, “Learning How to Correct a Knowledge Base from the Edit History” and “TableNet: An Approach for Determining Fine-grained Relations for Wikipedia Tables” will be live-streamed this Wednesday, March 20, 2019, at 11:30 AM PST/18:30 UTC (Please note the change in time in UTC due to daylight saving changes in the U.S.). The first presentation is about using edit history to automatically correct constraint violations in Wikidata, and the second is about interlinking Wikipedia tables. YouTube stream: https://www.youtube.com/watch?v=6p62PMhkVNM As usual, you can join the conversation on IRC at #wikimedia-research. You can also watch our past research showcases at https://www.mediawiki.org/wiki/Wikimedia_Research/Showcase . This month's presentations: Learning How to Correct a Knowledge Base from the Edit History By Thomas Pellissier Tanon (Télécom ParisTech), Camille Bourgaux (DI ENS, CNRS, ENS, PSL Univ. & Inria), Fabian Suchanek (Télécom ParisTech), WWW'19. The curation of Wikidata (and other knowledge bases) is crucial to keep the data consistent, to fight vandalism and to correct good faith mistakes. However, manual curation of the data is costly. In this work, we propose to take advantage of the edit history of the knowledge base in order to learn how to correct constraint violations automatically. Our method is based on rule mining, and uses the edits that solved violations in the past to infer how to solve similar violations in the present. For example, our system is able to learn that the value of the [[d:Property:P21|sex or gender]] property [[d:Q467|woman]] should be replaced by [[d:Q6581072|female]]. We provide [https://tools.wmflabs.org/wikidata-game/distributed/#game=43 a Wikidata game] that suggests our corrections to the users in order to improve Wikidata. Both the evaluation of our method on past corrections, and the Wikidata game statistics show significant improvements over baselines. TableNet: An Approach for Determining Fine-grained Relations for Wikipedia Tables By Besnik Fetahu Wikipedia tables represent an important resource, where information is organized w.r.t table schemas consisting of columns. In turn each column, may contain instance values that point to other Wikipedia articles or primitive values (e.g. numbers, strings etc.). In this work, we focus on the problem of interlinking Wikipedia tables for two types of table relations: equivalent and subPartOf. Through such relations, we can further harness semantically related information by accessing related tables or facts therein. Determining the relation type of a table pair is not trivial, as it is dependent on the schemas, the values therein, and the semantic overlap of the cell values in the corresponding tables. We propose TableNet, an approach that constructs a knowledge graph of interlinked tables with subPartOf and equivalent relations. TableNet consists of two main steps: (i) for any source table we provide an efficient algorithm to find all candidate related tables with high coverage, and (ii) a neural based approach, which takes into account the table schemas, and the corresponding table data, we determine with high accuracy the table relation for a table pair. We perform an extensive experimental evaluation on the entire Wikipedia with more than 3.2 million tables. We show that with more than 88% we retain relevant candidate tables pairs for alignment. Consequentially, with an accuracy of 90% we are able to align tables with subPartOf or equivalent relations. Comparisons with existing competitors show that TableNet has superior performance in terms of coverage and alignment accuracy. -- Janna Layton (she, her) Administrative Assistant - Audiences & Technology Wikimedia Foundation <https://wikimediafoundation.org/>

Sampling new editors in English Wikipedia
by Haifeng Zhang 19 Mar '19

19 Mar '19

Hi folks, My work needs to randomly sample new editors in each month, e.g., 100 editors per month. Do any of you have good suggestions for how to do this efficiently? I could think of using the dump files, but wonder are there other options? Thanks, Haifeng Zhang
