Synonyymivirtaa

Synonyymivirtaa is a cross-lingual lexical resource and streaming API designed to provide context-aware synonyms for words and phrases. The name combines synonyymi (Finnish for synonym) and virtaa (flow), reflecting its aim to deliver a continuous stream of alternative expressions.

Data and methods: It draws from curated dictionaries, aligned thesauri, parallel corpora, and statistics-based semantic models. For a given input sentence, the system performs word-sense disambiguation and then surfaces sense-appropriate synonyms, ranked by relevance, style, and register. The streaming API returns results incrementally to support interactive writing tools and editors.

Scope and availability: initial scope covers Finnish and English with Nordic languages; expansion to additional languages is planned as data and licensing allow.

Applications: writing assistance, translation, education. It can be integrated into word processors, content management systems, and chat applications. The project is maintained as an open platform, with community contributions welcome.

Limitations: quality varies by language; synonyms can be highly context-dependent; domain-specific terms may be underrepresented; datasets may reflect licensing constraints. Privacy and security: user text is processed on servers, or locally in configurable deployments.
