WikiCite 2016/Proposals/Retrieving Wikidata statements by source

Proposal

Background

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list all statements citing a specific journal article that was retracted
list all statements citing a source that cites a specific journal article that was retracted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

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

this is where you can link to any demo

Skills needed

knowledge of SPARQL and familiarity with WDQS
curiosity about research questions we've never been able to answer before

Phabricator task

if you have a Phabricator task ID, you can link it here
