SQID is a data browser for Wikidata that integrates data from various sources, including the Wikidata Query service, the Wikidata API, Wikidata dumps (analysed offline), and further Wikimedia sources. It features class and property browsers, and provides a concise display of both outgoing and incoming statements for items.
A recent addition to SQID is the integration of proposals from Primary Sources, where proposed references may be approved or rejected with just a single click.
We extend SQID with a reasoning component that is able to infer new statements from existing data. These rules can be used to:
- materialise statements that should be present, but are not (such as inverses of “spouse” statements);
- find inconsistencies in the data (e.g., statements missing mandatory qualifiers); and to
- display statements that logically follow from the data, but do not need to be materialised (e.g., “relative” statements obtained from following “father”/“mother”-paths).
Rules of the latter type contribute to a better browsing experience by making explicit data that could only be obtained by combining different statements (not necessarily belonging to the same item), whereas rules of the former types help to improve the quality of the data itself.
After introducing the basic usage of SQID, we will demonstrate applications for rules in the use cases above, and have discussions with interested participants regarding the next steps for reasoning on Wikidata.
