WordAtlas is a multilingual knowledge graph. It links 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

While BabelNet is a merger of open knowledge resources such as Wikipedia, Wiktionary and WordNet, WordAtlas adds professionally-curated language content and additional features in order to set a level playing field across languages and enable multilingual Natural Language Processing with high accuracy.

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.
