Wikimedia Discovery

The Discovery Department of Wikimedia Engineering has the mission to make the wealth of knowledge and content in the Wikimedia projects easily discoverable. We have a number of projects detailed below that focus us on creating and supporting new forms of discovery.

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.

Search Analytics Dashboard - Public dashboard to monitor and analyze the impact of our efforts.

Current Goals (FY 2016-17 Q2)

 * Enable the backend for cross-project indices on all Wikimedia projects.
 * Enrich the data stored in ElasticSearch to allow targeted improvements to result relevance.

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.

Portal Analytics Dashboard - Public dashboard to monitor and analyze the impact of our efforts.

External Search Traffic - External search engines metric that very broadly looks at where our requests are coming from.

Current Goals (FY 2016-17 Q2)

 * No dedicated goals this quarter (See the note below this table for more information)

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.

Work by this team is tracked on this Phabricator workboard

The team's roadmap can be viewed ; it was finalized in Nov 2016 for FY 2016/2017.

Maps Analytics Dashboard - Public dashboard to monitor and analyze the impact of our efforts.

Current Goals (FY 2016-17 Q2)

 * Increase maps and graphs usage on Wikipedia
 * Enable shareable Geoshapes and Tabular data storage on Commons

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.

WDQS Analytics Dashboard - Public dashboard to monitor and analyze the impact of our efforts.

Current Goals (FY 2016-17 Q2)

 * Wikidata Query Service will not have any dedicated goals this quarter.

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 and even more information on how they do their analysis and the impact (on Meta).

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

Current Goals (FY 2016-17 Q2)
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.

API Analytics Dashboard - Public dashboard to monitor and analyze the impact of our efforts.

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

The team
Below is a list of sub-teams in the Discovery Department. This list was last updated on 17th October 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.
