BabelNet 5.0 API (for quick start and programmatic access to BabelNet)

BabelNet Java API version 5.0 (February 2021 - Size: 22M)
The BabelNet Java API is a Java binding to our online HTTP RESTful service or can be used with the BabelNet indices. It provides classes, types and methods to work with BabelNet data. If you would rather use the raw HTTP API, please read the HTTP guide.

A fully-compatible BabelNet Python API is developed by Babelscape for WordAtlas. The API provides a full set of classes and methods equivalent to the Java API. Go and check it out in the WordAtlas API section.
