OpenTapioca is a simple and fast Named Entity Linking system for Wikidata. It is kept synchronous with Wikidata in real time, encouraging users to improve the results of their entity linking tasks by contributing back to Wikidata.

A live instance is running at https://opentapioca.org/. To run it on a server that is powerful enough, I would need 50€/month: please help fund the service if you can.

A NIF endpoint is available at:

• https://opentapioca.org/api/nif (only exposing the matches that are deemed good enough)
• https://opentapioca.org/api/nif?only_matching=false (also exposing all the other matches regardless of their score)

See the docs for more information about how it works and how to run it. See the paper for some more motivation about the design of the system.

OpenTapioca is released under the Apache-2.0 license.
