Lexical Semantics

 Lexical Semantics by D. A. Cruse is one of my go-to resources when working on #NLP solutions. Discovering or categorizing sense relationships between words is one of the essential tasks in natural language processing applications. The problem typically lies in that all terms contain sets of relationships at various levels of importance or relevance. Sometimes, the task is to discover the important ones. Another time, the focus is to find those rare connections. Frequency-based methods usually provide a measure of importance. There are two general classes of semantic relationships that I’m currently working on: syntagmatic and paradigmatic. Syntagmatic connections exist between meanings located at a certain distance in the analyzed data structures, e.g., the same sentence, paragraph, or chapter. Paradigmatic relations exist between definitions situated in the same location within the grammatical string. Often, natural language processing of paradigmatic relations involves finding relevant synonyms. #naturallanguageprocessing #semantics
