Sanastotietoja

Sanastotietoja is a Finnish compound term that can be translated as "vocabulary data" or "lexical information." It refers to structured collections of words, terms and related metadata used for language description, terminology management, lexicography and language technology. Sanastotietoja may appear as glossaries, termbases, lexical databases or entries in corpora and dictionaries.

Typical contents include headwords, part of speech, morphological forms, definitions, translations, usage examples, domain labels and semantic relations such as synonyms and antonyms. In computational contexts sanastotietoja are often enriched with identifiers, frequency counts, pronunciation, part‑of‑speech tags and links to ontologies or interlingual resources.

Sources and methods for creating sanastotietoja range from manual expert curation and crowd‑sourcing to automated extraction from text corpora and parallel corpora with alignment tools. Standards and frameworks commonly used for structuring such data include the Lexical Markup Framework (LMF), ISO data categories and SKOS for terminologies.

Applications include machine translation, information retrieval, terminology work in specialized domains, language learning tools and linguistic research. For morphologically rich languages like Finnish, sanastotietoja must address inflectional paradigms and compounding, which increases the need for morphological annotation and lemmatization. Challenges include ensuring coverage, handling polysemy and sense distinctions, keeping datasets up to date and addressing licensing for reuse.
