WikiCite 2016/Proposals/Retrieving Wikidata statements by source
Appearance
Proposal
[edit]Background
[edit]One of the unique benefits of representing source metadata as linked open data (cross-referencing sources and existing items and statements in Wikidata) is the ability to perform arbitrary queries on sources (via the Wikidata Query Service). Here's a few examples:
- list all Wikidata statements backed by a New York Times article
- list the most popular scholarly journals used as sources of statements for any item that is a subclass of economics
- retrieve all statements citing the works of Joseph Stiglitz
- retrieve all statements citing journal articles
- by physicists from Oxford University
- that have a PubMed Central ID
- list all statements citing a specific journal article that was retracted
- list all statements citing a source that cites a specific journal article that was retracted
- all Zika-related journal articles that were published in the last four weeks
Aim
[edit]- discuss and prioritize the most important types of source-related queries that WDQS should support
- determine if these queries can be effectively expressed in SPARQL and executed via WDQS or if they require a different indexing / data modeling strategy
Demo
[edit]- this is where you can link to any demo
Skills needed
[edit]- knowledge of SPARQL and familiarity with WDQS
- curiosity about research questions we've never been able to answer before
Phabricator task
