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 Q1) Goals [(link)]:
 * Zero results rate cut in half, from approximately 25% to approximately 12.5%.
 * No decrease in user clickthrough rate from search results.

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

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.

Current (FY 2015-16 Q1) Goals [(link)]:
 * Wikimedia Maps Tile Server is deployed and usable from within our cluster.
 * Define metrics and KPIs for the service.
 * Display metrics and KPIs on the Discovery Department dashboards.

Ops support: User:JCrespo_(WMF) and [User:Akosiaris]

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.

Current (FY 2015-16 Q1 Goals [(link)]:
 * Wikidata Query Service is deployed and usable from within our cluster.
 * Wikidata Query Service keeps with Wikidata update stream.
 * Define metrics and KPIs for the service.
 * Display metrics and KPIs on the Discovery Department dashboards.

Wikimedia.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].

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