WordAtlas: a huge multilingual knowledge graph

Knowledge bases and knowledge graphs are the 21st century counterpart of dictionaries in previous centuries. They organize knowledge into a coherent network of meanings and they enable Artificial Intelligence applications which exploit this knowledge to perform text understanding.


WordAtlas is the next-generation multilingual knowledge graph. It greatly enhances BabelNet®, the award-winning multilingual semantic network, thanks to the know-how of years of research in computational linguistics in Prof. Roberto Navigli’s lab at the Sapienza University of Rome.


What makes WordAtlas special is its linkage between concepts and words in hundreds of languages: WordAtlas provides millions of lexicalizations for each language, from common nouns, adjectives, verbs and adverbs, to hundreds of thousands of technical terms and millions of named entities, such as people, locations, organizations and products.


Each meaning comes with a wealth of information, including:

  • synonyms in dozens of languages
  • definitions (often multiple) in each language
  • taxonomical information: generalizations (i.e., more general concepts) and specializations (i.e. more specific concepts)
  • thousands of different relations (such as, part-of, used-for, born-in, located-in, related-to)
  • pictures which illustrate concepts

Knowledge graph and multilingual dictionary API

WordAtlas comes with high-performance API for Python and Java (therefore supporting all JVM-based languages, such as Kotlin, Scala and Groovy). The API enables access to the multilingual knowledge graph and includes a wide range of methods for:

  • searching by word and concept id;
  • retrieving information about concepts and entities, such as multilingual lexicalizations (synonyms), definitions, examples, semantic relations (e.g. hypernymy, meronymy, relatedness, born-in, etc.), links to images and much more;
  • support of functional programming, enabling the use of lambda functions for querying and retrieval purposes.

The Python API mimics the organization of the Java API, therefore making it easy to switch from one to the other. The APIs support both online and offline querying of WordAtlas and come with professional support.


The Python and Java API are fully compatible with BabelNet. Please contact us for more details.

The Next-Generation BabelNet®

WordAtlas greatly innovates the award-winning BabelNet®, the largest multilingual semantic network, encyclopedic dictionary and knowledge repository for multilingual applications, which covers 22 million concepts and named entities in 520 languages.


BabelNet received the 2015 META prize for the "groundbreaking work in overcoming the language barriers" and the Prominent Paper Award 2017 from the Artificial Intelligence Journal.


WordAtlas builds upon this success and takes BabelNet to the next level, by improving the underlying lexical-semantic model and providing professionally-curated content.
