This paper presents a two-agent framework to build a natural language query interface for IC information system, focusing
more on scope queries in a single English sentence. The first agent, parsing agent, syntactically processes and semantically
interprets natural language sentence to construct a fuzzy structured query language (SQL) statement. The second agent, defuzzifying
agent, defuzzifies the imprecise part of the fuzzy SQL statement into its equivalent executable precise SQL statement based
on fuzzy rules. The first agent can also actively ask the user some necessary questions when it manages to disambiguate the
vague retrieval requirements. The adaptive defuzzification approach employed in the defuzzifying agent is discussed in detail.
A prototype interface has been implemented to demonstrate the effectiveness.

本文从国有企业本身的特点(内因)出发,把国企分为三类,不同类型的国企用不同的产权制度(外因)去对症下药,于是引出国企改革的三分法。同时借鉴国外国有经济行业分布,认为我国国有经济应实行有针对性的战略收缩,把国有经济从量的扩张转移到质的提高上来。 相似文献
