Hi all,

I am forwarding you this email, because we have a specific technical question. With DBpedia as middleware, we can create a global view on all the data that is in Wikipedias Infoboxes and Wikidata and compare them (for details see the email below and also the proposal).

We were wondering what is the latest and most appropriate tech to interface with the editors of infoboxes.

VisualEditor seems appropriate, but I checked here for example: https://en.wikipedia.org/wiki/Fulda

It seems to be possible to edit some values, but there is no Wikidata support and also population does have a reference which does not show up in the VisualEditor.

Do you think it would be a good way to provide comparative facts from other language versions in the VisualEditor? Or would you choose something else?

All the best,

Sebastian

Dear all,

last year, we applied for a Wikimedia grant to feed qualified data from Wikipedia infoboxes (i.e. missing statements with references) via the DBpedia software into Wikidata. The evaluation was already quite good, but some parts were still missing and we would like to ask for your help and feedback for the next round. The new application is here: https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/GlobalFactSync

The main purpose of the grant is:

- Wikipedia infoboxes are quite rich, are manually curated and have references. DBpedia is already extracting that data quite well (i.e. there is no other software that does it better). However, extracting references is not a priority on our agenda. They would be very useful to Wikidata, but there are no user requests for this from DBpedia users.

- DBpedia also has all the infos of all infoboxes of all Wikipedia editions (>10k pages), so we also know quite well, where Wikidata is used already and where information is available in Wikidata or one language version and missing in another.

- side-goal: bring the Wikidata, Wikipedia and DBpedia communities closer together

Here is a diff between the old an new proposal:

- extraction of infobox references will still be a goal of the reworked proposal

- we have been working on the fusion and data comparison engine (the part of the budget that came from us) for a while now and there are first results:

6823 birthDate_gain_wiki.nt 3549 deathDate_gain_wiki.nt 362541 populationTotal_gain_wiki.nt 372913 total

We only took three properties for now and showed the gain where no Wikidata statement was available. birthDate/deathDate is already quite good. Details here: https://drive.google.com/file/d/1j5GojhzFJxLYTXerLJYz3Ih-K6UtpnG_/view?usp=s...

Our plan here is to map all Wikidata properties to the DBpedia Ontology and then have the info to compare coverage of Wikidata with all infoboxes across languages.

- we will remove the text extraction part from the old proposal (which is here for you reference: https://meta.wikimedia.org/wiki/Grants:Project/DBpedia/CrossWikiFact). This will still be a focus during our work in 2018, together with Diffbot and the new DBpedia NLP department, but we think that it distracted from the core of the proposal. Results from the Wikipedia article text extraction can be added later once they are available and discussed separately.

- We proposed to make an extra website that helps to synchronize all Wikipedias and Wikidata with DBpedia as its backend. While the external website is not an ideal solution, we are lacking alternatives. The Primary Sources Tool is mainly for importing data into Wikidata, not so much synchronization. The MediaWiki instances of the Wikipedias do not seem to have any good interfaces to provide suggestions and pinpoint missing info. Especially to this part, we would like to ask for your help and suggestions, either per mail to the list or on the talk page: https://meta.wikimedia.org/wiki/Grants_talk:Project/DBpedia/GlobalFactSync

We are looking forward to a fruitful collaboration with you and we thank you for your feedback!

All the best Magnus
