Abstract
Conventional computing which processes information, such as artificial intelligence, and natural language processing which is computing of language, have been perceived individual processing. However, human intelligence is supported by the functions of language, if we wish to realize human intelligence on a computer, we have to fuse these computing and achieve a framework for computing in which any information is processed with language. Based on this idea, the concept of everyday language computing has been proposed. In this paper, for a concrete example of everday language computing, we develop a dialogue system for travel consultation which interprets a user's intentions by understanding the meaning produced by words in a consultation dialogue, and then we show the process of how travel information required by a user will be retrieved based on the meanings the system obtained through the dialogue. As a framework for processing the meaning of a dialogue, we adopt the framework for a meaning base, which is defined in systemic functional linguistic theory as a human experience model constructed based on the linguistic system. And we analyze and generate meaning of speech by applying the meaning base to travel consultation, and try information processing with the meaning of speech. And then we show the practicability of our proposing method through the dialogue simulation system.
