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.

Learn more about Search and the current work of the team.

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

Current Goals (FY 2016-17 Q1)

 * Improve search result relevance and enable fixes for multiple relevance issues by switching from tf–idf to BM25.
 * Evaluate and devise plan for using cross-project indices, which would allow users to search across all projects in any given language.

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 work around the Wikipedia.org portal project.

Current work by this team is tracked on this Phabricator workboard and a listing of upcoming A/B tests can be found here.

Current Goals (FY 2016-17 Q1)

 * Make the www.wikipedia.org portal a jumping off point to explore 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 2016-17 Q1)

 * Make  tag available for all wiki projects, and   available everywhere except Wikipedia. Heavy operations participation will be needed to stabilize map server configuration and monitoring.
 * Offer community a way to migrate away from GeoHack by implementing a Special page (for legacy browsers) and extend  with configurable links to other mapping services information tab.

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

Weekly deployments of WDQS are documented on Deployments.

Current Goals (FY 2016-17 Q1)

 * TBD

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

Learn more about the Discovery analysis team.

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

Current Goals (FY 2016-17 Q1)
FDS Plan 2016/2017
 * This quarter, instead of having team-specific goals, the analysis team will be supporting the other team's goals.

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.

The team
Below is a list of sub-teams in the Discovery Department. This section was last updated on 20th July 2016.

Each sub-team lists the names and team roles (not job titles; those are listed in the staff and contractors page, and may or may not be the same as the person's team role) of anyone who spends a not insignificant amount of time on a project; this therefore means that some names are duplicated across teams.

These lists are only intended to roughly convey who is working on what; no guarantees are made that the list is accurate to any particular level of detail. If you have questions, please contact Dan Garry.
