Wikimedia Discovery

The Discovery department of Wikimedia Engineering is building the anonymous path of discovery to a trusted and relevant source of knowledge. You can find all of our data and key performance indicators on our data portal.

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 Wikimedia.

Current (FY 2015-16 Q2) Goal (link):
 * Improve language support for search.

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

Wikipedia.org portal
Many users discover Wikimedia via [], so Discovery will be looking at how to improve the user experience on that page. Here is an [initial analysis].

Current (FY 2015-16 Q2) Goal (link):
 * 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, OpenStreetMap/Production maps cluster is a project to make OpenStreetMap available on all Wikimedia projects, at a scale sufficient for their widespread usage. The main sub-project page is here: Maps.

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.

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

Current (FY 2015-16 Q2) Goals (link):
 * Improve understanding of user satisfaction for search by iterating and improving on the search satisfaction metric.
 * Support ongoing evaluation of usage of Wikidata Query and Maps services to decide on what's next for these services.
 * Create recurring performance indicator on referrer traffic from the primary search engines and determine what features may have largest impact on referrer metric

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

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