Computational lexical semantics - PowerPoint PPT Presentation

Componential analysis is a significant theory that emerged in the 20th century to analyze words based on semantic features. It helps identify word meanings by examining components and their features. This method involves representing features as either positive (+), negative (-), or unspecified (.).
