A perception based, domain specific expert system for question-answering support

The ability to search has become an integral part of our interaction with technology. However, the current search technologies mostly use a keyword based searching mechanism, which does not have any deductive abilities. The recent introduction of the idea of computing with words, which can give deduction abilities to existing technologies, provides a new base for developing frameworks. This paper proposes implementation of a domain specific fuzzy expert system based on a question-answer system, which employs computing with words. In order to perform the translation of natural language sentences into a standard format, probabilistic context-free grammar is used.
