semanticrelatedness
Semanticrelatedness is a measure of the degree to which two linguistic items (words, phrases, concepts) are connected in meaning within a language or knowledge representation. It captures associative, functional, and contextual connections that may not entail substitutability. By contrast, semantic similarity refers more narrowly to likeness in properties or roles and is often symmetrical; semanticrelatedness is broader and can be asymmetric in some settings.
Methods: Semanticrelatedness can be assessed via knowledge-based approaches using structured resources such as WordNet or ontologies,
Applications: evaluation of lexical semantic tasks, information retrieval, document clustering, question answering, and sense disambiguation. Semanticrelatedness
Challenges: context dependence, polysemy, domain specificity, and cross-lingual transfer. The notion is inherently task- and domain-dependent;
