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.

Projects[edit]

Search[edit]

Discovery is responsible for maintaining and enhancing the various Search features and APIs for MediaWiki. This includes the CirrusSearch extension which relies on, 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 Q4)[edit]

  • Improve search by researching and load testing machine learning to automatically re-rank search results
  • Improve support for different languages by researching and deploying new language analyzers

Wikipedia.org portal[edit]

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 initial analysis 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 Q4)[edit]

  • No dedicated goals this quarter.

Maps[edit]

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 here; 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 Q4)[edit]

  • Stabilize maps and graphs code base

Wikidata Query Service (WDQS)[edit]

Searching structured data on Wikidata is also part of Discovery, so we are building the Wikidata query service. It provides a 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 wikitech:Deployments.

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

Current Goals (FY 2016-17 Q4)[edit]

  • No dedicated goals this quarter.

Analysis[edit]

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 Q4)[edit]

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

APIs[edit]

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.

For general questions about the work of the Discovery department, please see the FAQ.

An overview of Discovery's narrative and roadmap for FY 2016/17 (July 2016 - June 2017)

For any questions about the term "Knowledge Engine" please refer to this FAQ.

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

The team[edit]

Below is a list of sub-teams in the Discovery Department. This list was last updated on June 8th, 2017.

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 Deb Tankersley.
