A Perception Based, Domain Specific Expert System for Question-Answering Support

The current search engine technologies mostly use a keyword based searching mechanism, which does not have any deductive abilities. There is an urgent need for a more intelligent question-answering system that will provide a more intuitive, natural language interface, and more accurate and direct search results. The introduction of computing with words (CwW) provides a new theoretical base for developing frameworks with support for dealing with information in natural language. This paper proposes a domain specific question-answering system based on fuzzy expert systems using CwW. In order to perform the translation of natural language based information into a standard format for use with CwW, probabilistic context-free grammar is used
