Title: Interpreting Intentions of Speech
Many scientists (Cohen et al., 1990) have tried to interpret intention through logical inference. However, lacking an effective means of semantic analysis, the results were not very satisfying. Vanderveken (1990) tried to construct a logic of illocutionary force. But he couldn’t reveal the semantic implications, because he couldn’t explain how different illocutionary forces compose as a whole. This paper’s purpose is to reveal the mechanism of interpreting intentions of speech. Firstly, we present a grammar system for extracting the semantic structures of intentions. The grammar system includes a taxonomy of intentions of speech, which is based on Speech Act Theory (Searle, 1969; Grice, 1989) and Searle’s philosophy about “social reality” (Searle, 1997), and a set of grammar rules. Then, we give a logic of semantic implication to explain how people understand and respond to the implicit meanings of complex intentions, such as an imperative hidden in a query, and a query embedded in an indirect speech.
