RIsler (WMF), the Structured Data product manager, has identified an issue that he'd like to bring to the community's attention, with regards to how search will function:
After review with many engineering and product folks at WMF, WMDE, and within the Commons community, we've come to understand that the initial implementation of depicts "tags" for Commons media should be more focused on making sure all relevant concepts are identified and tagged, rather than limiting tagging to a few specific terms. Additionally, for now we won't rely much on the Wikidata ontology (the data structured) to find any additional depicts statements automatically.
Here is an example of what we mean. Let's try the hypothetical case of an image of a German Shepherd, and the user uploading it tagged it with only "German Shepherd" (Wikidata item d:Q38280):
- We may be able to suggest an additional depicts tag (dog, d:Q144) based on the "subclass of" or "instance of" property of German Shepherd (we are still determining if this is possible for the initial version of depicts functionality). These suggested tags could appear during use of the UploadWizard, or on the image's file page, and be available for a human to confirm their accuracy before being added to the file's data.
- In the first half of 2019, we expect to launch a machine-based image classification feature that may suggest a number of additional depicts tags including "dog" (d:Q144), "pet" (d:Q39201), "canine" (d:Q2474088), etc. These suggested tags could appear on the image's file page and be available for a human to confirm their accuracy before being added to the file's data.
- Once a suggested tag is confirmed, it is added as a depict statement and the German Shepherd image will show up as a match for searches for any of those terms.
- On the file page, users will be free to add additional depicts tags that are accurate for the image (for instance, if it's a young dog, add puppy (d:Q39266) )
This combination of techniques should ultimately result in better searches that can be both very specific (show me German Shepherd puppies) and broad (show me pets).
