NooJ is a linguistic development environment that includes large-coverage dictionaries and grammars, and parses corpora in real time.

NooJ includes tools to create and maintain large-coverage lexical resources, as well as morphological and syntactic grammars. Dictionaries and grammars are applied to texts in order to locate morphological, lexical and syntactic patterns and tag simple and compound words.

NooJ can build complex concordances, with respect to all types of Finite State and Context-Free patterns.

NooJ users can easily develop extractors to identify semantic units in large texts, such as names of persons, locations, dates, technical expressions of finance, etc.
