Synonymlisten

Synonymlisten is a linguistic resource consisting of curated lists of synonyms organized by sense. It functions as a lexical database that captures semantic relationships such as synonymy, near-synonymy, and related terms. The project aims to provide researchers, educators, and developers with a structured repository that supports natural language processing, lexicography, and language learning.

Entries in Synonymlisten typically cover a lemma with one or more senses, each sense listing synonyms that are interchangeable within that sense. Additional notes may indicate usage constraints, nuance, formality, or regional variation. Some implementations also include antonyms, collocations, frequency indicators, and multilingual mappings to connect terms across languages.

Data sources for Synonymlisten generally combine traditional dictionaries and thesauri with corpus evidence and computational methods. Quality control often involves expert review, cross-linguistic validation, and automated consistency checks. Licensing varies between projects, with some adopting open licenses to encourage reuse and others maintained by publishers or institutions under more restrictive terms.

Applications of the resource include improving search and information retrieval, enhancing machine translation and text generation, supporting language education, and aiding lexicographic research. Synonymlisten can function as a standalone database or be integrated into larger lexical ecosystems, such as multilingual dictionaries or speech and writing tools.

Limitations include challenges in sense disambiguation, context dependence of synonymy, and register or cultural differences in word usage. Ongoing work typically addresses expanding coverage, refining sense inventories, and improving cross-language mappings to reflect real-world usage.
