Wikimedia Discovery

The Discovery department of Wikimedia Engineering is building the anonymous path of discovery to a trusted and relevant source of knowledge. We have a number of projects detailed below that focus us on creating and supporting new forms of discovery for the users of the Wikimedia wikis. For any questions about the term "Knowledge Engine" please refer to our FAQ.

You can find all of our data and key performance indicators on our data portal.

Come help us decide what we work on in the future with our request for comments.

Search
Discovery is responsible for maintaining and enhancing the various Search features and APIs for MediaWiki. This includes the CirrusSearch extension which relies on Elasticsearch the search backend used at the Wikimedia Foundation to support Wikimedia projects.

Current work by this team is tracked on this Phabricator workboard.

Current Goals (FY 2015-16 Q3)

 * Improve relevance of intra-wiki search results (see a small demo comparing the new suggester to the current)
 * Generate a model for user satisfaction with search results based on qualitatively-validated quantitative data.

Wikipedia.org portal
Many people discover Wikipedia via https://www.wikipedia.org/ (roughly 1.5-2% of our total page views). The Discovery team is looking at how to improve the user experience for these visitors. Here is an from the Discovery team.

Learn more about the Wikipedia.org Portal Improvements project.

Current work by this team is tracked on this Phabricator workboard.

Current Goals (FY 2015-16 Q3)

 * Make www.wikipedia.org a portal for exploring open content on Wikimedia sites.

Maps
Discovery is about finding and navigating to content, and one way for users to do that is via maps. To provide better maps the team is working to make OpenStreetMap tiles available on all Wikimedia projects. The technical challenge is doing so at a scale sufficient for their widespread usage.

Learn more about the Maps project.

Current Goals (FY 2015-16 Q3)

 * Improve the content discovery experience on Wikivoyage by rolling out maps to all Wikivoyages.

Wikidata Query Service (WDQS)
Searching structured data on Wikidata is also part of Discovery, so we are building the Wikidata query service. It provides a SPARQL API through which tools can access Wikidata.

Learn more about the Wikidata query service.

Current work by this team is tracked on this Phabricator workboard

Current Goals (FY 2015-16 Q3)

 * Support ongoing stability and add ability to support geoocordinate functionality by upgrading Wikidata Query Service to Blazegraph 2.0.

Analysis
The analysis group within Discovery manages the Discovery Dashboard, as well as analyzing A/B tests and other data.

Current work by the analysis team is tracked on this Phabricator workboard

Current Goals (FY 2015-16 Q3)

 * This quarter, instead of having team-specific goals, the analysis team will be supporting the other team's goals this quarter.

APIs
Application Programming Interfaces (APIs) provide developers ways to interact with the MediaWiki software.

API:Search and discovery lists the search APIs available and in development.
