Hackathon Summary



1. Classification task force/notice board for Wikidata

It was pointed out that a wide range of different decisions are being made by Wikidata editors when trying to classify items using the "Instance of" and "subclass of" properties, and that the structure that is defined by these properties is really crucial for running efficient and successful queries on the data. There is a risk of getting into a similar mess as the Wikipedia category system if there isn’t some careful consideration keeping it as uniform as possible. All present agreed that having a task force, or noticeboard would be a great help. Basically a place where you can always post your questions about classifying a particular item (or entire class of items). A core group of community members with experience in classification could then answer those queries and help encourage more uniform usage.

2. Tool for determining why a particular item is a result of a query

The tool would take in 2 bits of information:

  • WDQ query
  • Q number of an item that should not have been in the list of results to the query given.

It would then display the parts of the class tree that connected the item to the query. The idea being that you can quickly identify and fix the exact item that has an incorrect class statement on it.

For example, the tool could display this tree if you were trying to find out why a psychopath turned up in your query for people with occupation = scientists (or any subclass of):


After-hackathon-thought: Although this be very handy as a stand alone tool, an option in AutoList would also be great! So you could run a query, then click on an item to show why it is in the list of results for the query.

3. Ranking system for Wikidata items

Histropedia is planning on creating a ranking system for Wikidata items, based on Wikipedia backlink counting across all languages. It seems evident that this will be useful to many more projects than just Histropedia. Obvious uses spring to mind, like having AutoList results ranked by ‘importance’, sorting Wikidata search results, or selecting the ‘top 50’ results of a query. If lots of people feel this will be useful to have, we should consider building and maintaining the rank list on Labs instead of developing it externally.

4. Tool for plotting a timeline of references using Histropedia

A tool was proposed that would allow you to see the references for any Wikipedia article visualised on a Histropedia timeline (by publication date). The tool would retrieve the list of references from a Wikipedia article, then use the Wikidata items for each reference to pull the necessary data for plotting a timeline (e.g. date of publication, image and link to the reference on Wikisource). Obviously the usefulness of the tool will depend on the number of references that we can get properly described on Wikidata, so hopefully it could serve as good motivation for editors.

Follow up tasks

  • Post a message on Wikidata project chat about the Classification task force / notice board idea.
  • Plan and propose tool for identifying –why-- items incorrectly appear in a query (run this past Magnus for feasibiliy check)
  • Post message to project chat about using Wikipedia backlink counting as a ranking system for Wikidata items to gauge interest.
