摘要
PURPOSE: A summary information production system and a method about a product or service related review are provided to use a domain dependent word which applied the statistics technique or the continuous word extraction, thereby effectively extracting an evaluation component and opinion about the summary of the product or service. CONSTITUTION: A review data obtaining unit (10) obtains the review data about the product or service. A pre-processor unit (20) performs the sentence separation and the morphological analysis in the review data. A domain knowledge extracting unit (40) receives the review data and extracts the information related to the domain in which the product or service is included. An evaluation component-opinion extracting unit (50) receives the information and classifies the word corresponding to the evaluation component and the opinion. By using the word corresponding to the evaluation component and opinion, the evaluation component-opinion extracting unit extracts the opinion per evaluation component. An evaluation information generation unit (60) uses the opinion per evaluation component to produce the evaluation information about the product or service.
