NLUS is a Prolog-based natural language understanding system, which exploits multi-knowledge representation formalisms. Sentences input from the user are converted into semantic networks and/or production rules; whereas the grammar rules are represented in predicate logic. After processing a sentence, the software may initiate its inference engine to deduce a response. A question would also be parsed and converted into a semantic structure which may contain possibly some missing information. To find an answer to a question, the missing information may be extracted from another related semantic structure in the working memory. At present, the software can handle sentences with relatively simple syntactic structures and some restricted types of questions. However, intelligent man-machine dialogues can be realized. It is particularly good at handling the rule-oriented type of sentences and is considered a decent prototype for experimenting with natural language understanding
