Wikidata:Events/Data Quality Days 2022

<< 2021
Data Quality Days, 8-10 July 2022



Welcome!
The Data Quality Days is an online event designed for the Wikidata community and focusing on processes around data quality. During 3 days of presentations, workshops and facilitated conversations, we will discuss how we are currently identifying and fixing incorrect data on Wikidata, how we could improve these processes to increase data quality, and what concrete measures we could put in place together, with policies, tools or documentation.
Participation
The sessions are open to everyone involved in Wikidata and interested in the topic of data quality. The sessions took place on the online platform Jitsi. Some sessions have been recorded in video and uploaded to this Youtube playlist, and collaborative notes are accessible from the schedule. Slides from speakers are added to the Commons category Data Quality Days 2022 presentations. If you attended the event, feel free to add your name on the participants list! Please note that the entire initiative, including the presentations and discussions on various channels, is covered by the Code of Conduct for technical spaces. Please contribute in making the discussion spaces safe and welcoming for everyone.
Discussions and help
If you have questions or suggestions about the event, feel free to use the talk page. Announcements about the event are talking place on the same talk page, and on Wikidata Telegram group. If you want to reach out to the organizers directly, feel free to contact Lea Lacroix (WMDE) (lea.lacroix@wikimedia.de or @Auregann on Telegram).

Structured conversation #1: Round-tripping data

There are excellent gold-standard sources out there that Wikidata can use, but even those make mistakes. The same is true if you use data from Wikidata for your own project. Therefore, syncs from and to Wikidata should ideally go in both directions (so called “data round-tripping”). Unfortunately, it is currently not as simple as it should be to set this up sustainably.

Goals of the session:

  • Collect existing hurdles for setting up round-tripping
  • Additional collection (likely no focus in the discussion)
    • Share examples of where this works particularly well already (we could use these for sharing best practices)
    • Collect examples where building up new syncs with external sources would be of great benefit to data quality
  • Discuss how we can help users who want to set-up sustainable round-tripping
  • Find allies to improve the status-quo

Notes

How do we deal with concurrent uses of different properties? The example of modeling data for humans

The same information can sometimes be stored in different statements, thus making it very difficult to be found through a single query; I will show some examples, mainly from instance of (P31)human (Q5) items, and I will survey the existing ways of dealing with the problem and possible future solutions.

Discussion: Matching new Wikipedia articles to Wikidata items

New Wikipedia articles are continually being created, but they frequently aren't matched up with existing Wikidata items, leading to missing interwiki links, and duplicates on Wikidata. This session will discuss the status quo - including existing matching mechanisms, mass new item creations, and merging work - and identify ways to improve this work in the future.

Structured conversation #2: Rules and anarchy

Some policies and guidelines on Wikidata are not fully enforced in practice (e.g. Wikidata:Bots, Wikidata:Notability). Ignoring important rules can have negative consequences for the Community and data quality.

Goals of the session:

  • Collect examples for policies and guidelines that are currently ignored with negative consequences
  • Discuss possible solutions
  • Find allies to improve the status-quo

Structured conversation #3: Why isn’t there more guidance on this?

Doing the right thing on Wikidata is often harder than necessary. Some defaults and processes are annoying to the best of us and for new editors a lack of guidance can even be an unsolvable problem.  

Goals of the session:

  • Collect examples where missing guidance and bad defaults cause editors problems which eventually leads to lower quality data
  • Discuss possible solutions
  • Find allies to improve the status-quo

Using Lexemes in Abstract Wikipedia: how can we improve the data?

Abstract Wikipedia's ultimate goal is to automatically create articles in various languages using Natural Language Generation techniques. The success of any such approach will depend to an important extent on the quality of lexicographical and grammatical data in Wikidata. While data in Wikidata was designed to be machine-readable, it is not necessarily in the best shape to assist Abstract Wikipedia's mission yet. In the presentation we will examine the relevant data extant in Wikidata, and how it can be improved.

  44. 圍繞著如何「管理龐大的資料庫」,「讓資料庫能發揮最大的效用」,「中央樞紐的管制功能與地區樞紐的配合度」古代遺留的智慧如果沒人學習並且傳承給下一代,它屬於死物。任何人花費時間去學習把這些智慧實踐在日常生活當中,間接的影響了其他人的生活也因此提升品質。卻因為擁有權力的資產階級為了鞏固自身的利益,對於底層階級施加了各式各樣的枷鎖,社會的金字塔結構就一直存在。我的興趣只有接收資訊化為自己的知識,知識是一股沒人可以奪走的無形力量,金字塔結構的枷鎖只有善用知識的人群團結一致才有打破的機會。我想觀察這個理念能不能得到更多的共鳴!J.zht (talk) 15:04, 9 July 2022 (UTC)[reply]
