twoword

Twoword is a term used in linguistics and computing to describe two-word expressions, and it is also the name of an open-source software project that provides tools for working with such expressions. The project aims to simplify analysis and generation of two-word phrases for natural language processing tasks, tagging, and data preparation.

The Twoword library includes a phrase extractor that identifies two-word collocations in corpora, a normalizer that standardizes forms, and a generator that constructs plausible two-word phrases from a vocabulary. It can be used to augment keyword lists, create synthetic datasets, or improve search query understanding.

History and adoption: The project was released in 2018–2019 by a community of developers. It is hosted on a public code repository and distributed under an open-source license. Since its initial release, it has attracted contributors who add language support and platform bindings.

Implementation and scope: Twoword is implemented with language-agnostic core logic supplemented by language packs. Primary implementations exist in Python and JavaScript, with simple APIs that allow integration into data processing pipelines and web applications. The toolkit prioritizes a small footprint and clear documentation.

Use and terminology: In linguistics, two-word expressions are sometimes referred to as bigrams or collocations; the Twoword project uses this terminology and provides utilities for their extraction, scoring, and generation.
