Semantic analysis is the study of how meaning is conveyed in language. It involves examining the relationship between words and phrases in a given text to determine their intended meaning. This can include understanding the context of the words used, the underlying concepts they represent, and how they relate to each other in order to extract useful information from the text. Semantic analysis is used in various fields such as natural language processing, computational linguistics, and artificial intelligence to improve communication, information retrieval, and other language-based tasks.
