The Semantics of Semantics in Language Processing
In speech and language research, the semantics of an utterance always corresponds to the meaning of the utterance. Meaning however, is a concept that has been argued by philosophers for centuries, so in Language Processing, semantics has come to be used very differently in different applications. One can even make the case that although we believe we must program computers to represent the “semantics” of an utterance, we often have great difficulty as humans defining exactly what we want. The talk will give an overview of formal semantics, lexical semantics and conceptual semantics and then focus on how semantics is used in several application areas of Language Processing.
