[Wikidata-l] Edit Item Suggestions
by Finke, Moritz 11 May '14

11 May '14

Hi everyone, we would like all of you to try out a new website we created: The site finds Wikidata-Items, that are most likely missing certain properties. So just go there, select a property of your choice and see what items could profit from it. Item-Suggestions that are no longer relevant (because some of you followed the link and edited them ;) ) will be removed automatically in a timely manner. Btw we already plan on making it possible to edit the suggested items directly from the page. Link to the site: https://suggester.wmflabs.org/EditItemSuggestions/public Interesting Examples for some inspiration: Items that are missing "official language": http://suggester.wmflabs.org/EditItemSuggestions/public/?id=P37 Items that are missing "date of birth": http://suggester.wmflabs.org/EditItemSuggestions/public/?id=P569 Items that are missing "headquarters location": http://suggester.wmflabs.org/EditItemSuggestions/public/?id=P159 Item that are missing "record label": http://suggester.wmflabs.org/EditItemSuggestions/public/?id=P264 The underlying algorithm for finding the items is based on concepts/ideas described here:<https://github.com/Dacry/EditItemSuggestions#the-algorithm-is-based-on-conc…> https://github.com/Wikidata-lib/Wikidata.lib/wiki/Intelligent-Forms#2-sugge… We hope you have fun and are looking forward to your feedback.

[Wikidata-l] WP-geocoordinates filter by using Wikidata classes
by Tim Alder 11 May '14

11 May '14

Hello, I'm glad to can announce my last experiment working with Wikidata and Wikipedia-coordinates: http://tools.wmflabs.org/wp-world/wikidata/superclasses.php?lang=en This list shows how many objects we have in different classes and provide links to maps with only this specific class. I think it's much more useful than in the past where 80% of our coordinates were simply a "landmark". Now we have maps full with roller coaster or with museums. To create this tool I used properties "is instance of"[1] and "is subclass of"[2]. To extract this properties it was necessary to use "Wikidata Query". Now all classes, where an object is a member, are in a numerical array-element in the database. So with an index on this array it should have a good performances. Next steps are to try to bring more order inside this list and support the community to create more "is instance of"-entries in Wikidata. (Only 30% off all objects have such an entry).

[Wikidata-l] multilingual terminology properties in Wikidata
by Amir E. Aharoni 10 May '14

10 May '14

Hi, I am at a the Multilingual Web Workshop in Madrid. I had a discussion here with a person who specializes in multilingual terminology translation about how Wikipedia and its sister sites can be more useful and reliable for people who search for translations of terms from different professional fields - medicine, communications, law, etc. For example, if you go to the Wikipedia article [[Aorta]], how can you know that this term is actually recognized as the English term by any professional medical associations? And if you go to https://www.wikidata.org/wiki/Q101004 , how can you know the same things about each of the translations of this term? For example, how do you know that "Srdcovnica" is recognized as a Slovak term by any medical association or linguistic committee? By itself, the interlanguage link to Slovak is not reliable. A translator to Slovak can, of course, go to a website of a relevant linguistic committee and check the term there. But can it be more direct and machine-readable? A property could probably be created, which would hold an id of a term in such a terminology database, but would it be appropriate to include it in an item page, given that such information is language-specific? It seems reasonable to me, but I wanted to make sure that everybody find it acceptable. And if there are such properties already, I'd love an example :) -- Amir Elisha Aharoni · אָמִיר אֱלִישָׁע אַהֲרוֹנִי http://aharoni.wordpress.com ‪“We're living in pieces, I want to live in peace.” – T.

[Wikidata-l] When the source says the information provided is dubious
by David Cuenca 07 May '14

07 May '14

Hi, I'm having some cases where a work has been attributed to an author by a source, but the source itself says this attribution is "dubious", or it is contesting a previous attributions as "spurious". As I see it, the rank of the statement is not deprecated (in fact it is "normal" or even "preferred"), but I have no way of representing this "claim uncertainty" or "claim rebuttal". Is there any hidden parameter for this or should it be addressed with a qualifier? Cheers, Micru

[Wikidata-l] Classification of properties?
by Fredo Erxleben 05 May '14

05 May '14

Hello all, I am playing around with properties at the moment, especially filtering out a certain kind of properties. So I wondered if it wouldn't be a nice thing, if properties were classified in some way. Example: (Numbering is just for readability and does not hold any semantics) P… is the placeholder for the actual property-Id, did not want to look them all up 1) Relations 1a) Mathematical relations 1b) Relations in human interaction 1b1) Social relation 1b1a) P… (is employee of) 1b1b) P… (is heir to) 1b2) Biological relation 1b2a) P… (brother of) 1b2a) P… (sister of) … 2) External IDs … and so on, I think you get the idea. Has something like this bees discussed before? Cheers, Fredo
