synonymisering

Synonymisering is a term used in linguistics and information science to describe the process of identifying, mapping, and applying synonyms for words or terms. The goal is to increase lexical coverage, reduce repetition, and improve understanding, retrieval, or translation by recognizing that different words can express similar meanings in particular contexts. In practice, synonymisering can refer to both the manual construction of synonym sets and automated methods that generate or validate such sets.

In lexicography and language planning, synonymisering contributes to creating standardized vocabularies and controlled vocabularies. In information retrieval and natural language processing, synonymisering enhances search, indexing, and classification by linking synonyms to shared concepts, thereby improving recall without sacrificing precision. It is also used in language generation and machine translation to select appropriate lexical choices that align with target audience, style, and domain.

Common methods include building synonym lexicons or thesauri, leveraging lexical databases such as WordNet or language-specific equivalents, and employing automatic techniques based on distributional semantics, word embeddings, or pattern-based extraction. Domain-specific synonymization may require specialized corpora and expert input to capture technical terminology and usage.

Challenges include polysemy, where a word has multiple related senses, context sensitivity, and register or dialect differences that influence appropriate synonym choice. There is also the risk of overgeneralization, semantic drift, or inappropriate substitutions in sensitive texts. Evaluation typically involves precision and recall in retrieval tasks, user studies, and domain-specific benchmarks to ensure that synonym mappings improve understanding and access without introducing errors.
