Lists of things as entities in Wikidata
by Thad Guidry 16 Jun '15

16 Jun '15

In Freebase, we had bot scripts that went through and removed "Lists of Things" topic entities since they are lists of entities and not useful clumped together and normalized in a graph database. Does Wikidata have something similar or a user review process for deletion of these ? Ex. List of tallest buildings in Wuhan - https://www.wikidata.org/wiki/Q6642364 Thad +ThadGuidry <https://www.google.com/+ThadGuidry>

University automatically being College alias ?
by Thad Guidry 16 Jun '15

16 Jun '15

There are times when a few keywords are often interchanged with each other in different languages and dialects. It seems advantageous to somehow tell Wikidata Search that when someone types Harvard College to interchange and also look for Harvard University, and vice versa. An interchange mapping table might suffice just for this use case, or something else, dunno... How far in the future is this feature ? Roadblocks ?

Wikidata data dump: JSON versus XML
by gnosygnu 14 Jun '15

14 Jun '15

Hi. Currently, the dump service offers two different dumps for wikidata: * XML: http://dumps.wikimedia.org/wikidatawiki/latest/ * JSON: http://dumps.wikimedia.org/wikidatawiki/entities/ According to http://www.wikidata.org/wiki/Wikidata:Database_download, the JSON dump is listed as the recommended dump format. Also, at the time of writing, the JSON dump has been generating regularly every week whereas the XML dump has been delayed for 2+ months. Going forward, will both dumps continue to be supported? Or will the XML dump be phased out and only the JSON dump remain? Or are these plans still to be determined based on upcoming changes to the dumping infrastructure as per https://phabricator.wikimedia.org/T88728? If the JSON dump is to be the sole data format, is there any way to address the following omissions? * '''Non-JSON pages not available''': The JSON dump only provides JSON content-type pages in the main and property namespaces. Pages in other namespaces are not available, including the Main Page. For example, here are the counts from the 2015-03-30 dump id name count ---- ------------ ----- 4 Wikidata 10280 8 MediaWiki 2244 10 Template 4701 12 Help 779 14 Category 3073 828 Module 175 1198 Translations 83524 * '''Page metadata not available''' : For the JSON pages, the page_touched and page_id is not available. * '''Other tables not provided''': Other tables are not provided, notably categorylinks and page_props Thanks in advance for any information.

accessing data from a wikidata concept page
by Benjamin Good 12 Jun '15

12 Jun '15

I recently introduced wikidata to a (very computationally savvy) colleague by sending him this link: https://www.wikidata.org/wiki/Q423111 His response is indicative of an interface problem that I think is actually very important: "Is there a simple way to get the RDF for a given concept? The page seems to only present the english names for the concept and its linked concepts." Leaving aside RDF, it is really not straightforward for newcomers to get from a concept page like that to the corresponding structured data. This could be solved with the consistent addition of a simple link like "view json/xml/rdf" to each of the concept pages on wikidata. They would just be links to the API calls: e.g. http://www.wikidata.org/w/api.php?action=wbgetentities&ids=Q423111 in this case. As the concept pages themselves get tossed around a lot, such an addition could be extremely valuable in teaching the uninitiated what its all about and would come at very little cost - to me, this button is akin to the 'view source' action on web pages - an absolutely fundamental part of how the web grows - even now. -Ben

Data amplitude and representation
by David Cuenca Tudela 11 Jun '15

11 Jun '15

Hi, I am investigating some concepts about signal processing and relating them to data manipulation. It is somehow difficult because the way computer scientists relate to concepts is very dogmatic, something is either black or white, however I have not found much on "things that under certain circumstances can be considered black-ish, and under another set of circumstances can be considered white-ish" http://freethoughtblogs.com/singham/2012/06/25/shades-of-grey-optical-illus… In signal processing there is the concept of amplitude which is just the signal strength. For humans language is like an amplitude communication process where the receiver picks up not only the signal, but also its amplitude depending on context, awareness, previous knowledge, etc. factors which in turn can be considered waves being processed by the ontological biological-organizational complex, the body-mind. It is tough to describe that a certain concept might have a certain amplitude in some situations and other amplitude in other situations, and perhaps even harder to make a human interface for it. Has anyone attempted it in the past? If Q items are not static entities, what is the best way to convey that they are not? And is it possible or desirable at all? Perhaps these questions are more suitable for a Wikidata 2.0, or perhaps it is already doable, who knows. Any thoughts? Cheers, Micru

Re: [Wikidata] Historic buildings/National trust
by Mike Cummins 10 Jun '15

10 Jun '15

I have had an interesting correspondence with Historic England and have had a couple of spreadsheets detailing different information. I have linked these into a Fusion table: https://www.google.com/fusiontables/DataSource?docid=14xbBg7o-h-1IY2RwKji9n… Is any of this of use to Wikidata? I can extract, massage, whatever to most formats... Mike

Way to check how many claims there are per item-sitelink from WP article category or list
by Jane Darnell 10 Jun '15

10 Jun '15

Hi all, After looking at the list of items without any claims, I was wondering if I could help with the cleanup by checking the categories I am familiar with. Is there any way to get a breakdown of #claims per item given a list of items from, say, a Wikipedia category? Thanks in advance, Jane

No links, wrong data: Scottland's orphans need help
by Markus Krötzsch 08 Jun '15

08 Jun '15

Hi all, Looking at more "orphaned items", I found several pairs of items that look like these two: https://www.wikidata.org/wiki/Q17574663 https://www.wikidata.org/wiki/Q17569687 Same label and description, same coordinates, no Wikidata articles, "identified" by different Historic Scotland IDs. If you follow the ID links, however, you can see that the first of the items has data that does not match the ID, while the second is correct. The direct question is: How to fix these errors? There are other cases, such as Q17572335 and Q17570206. I did not do a systematic study, but something seems to have gone wrong here in more than one case. I cannot fix mass edits one by one without having a clue what has happened and why. The indirect question is: How can I find out who did this and maybe ask the person to fix it? The history is of no help (Reinheitsgebot/Widar). Posting every error in Wikidata to this list to ask also seems like a bad idea. Finally, the technical question is: Why is this even possible? I thought that, in each language, label+description are a key (globally unique), yet here we have many pairs of items with exactly the same label and description. Or is the problem that no description was entered and so the system does not apply the key? In any case, a data integration helper application that looks at equal labels+descriptions would probably make sense, especially for orphaned items. (As I know Wikidata, someone might well reply to this email with a link to where this is already found ;-). Regards Markus
