Research On Information Processing Of Chinese Web Text Based On Product Design

The paper roots in the project "Research of innovated appearance design based on the esthetician's brain model" (NO: 69973037), which is funded by National Natural Science Foundation. Aviation Foundation (NO.04H53063) also supports this paper. In this project, the exact and highly effective learning environment need to be constructed to make the brain model grow. Illumined by the project, the author expects to use the correlated text disposing technique, such as text filtering, information extraction and so on, to deal with the text set of web. It can make computer provide information supports for designers and brain model with the exact training sample. After the investigation of features of text set, the method including two steps that consists of filtering firstly and then extracting information is proposed. The work done is as following:1. Text filtering based on samples' common featureThe method that samples' common features express user's demands and match with text set to filter unnecessary text is proposed according to features of text set. The good accuracy of the method is proved by filtering experiment of text set. The method of text filtering based on samples' common feature is important innovative point in the work.2. The method of extraction of text information for product designAfter the study of general method of information extraction and analysis of situation of demand in the process of product design, to the complex conception of product, the enactment method of pattern of sub-goal of product with the basis of "product overall—sub-goal ('entity')—attribute—features of attribute" in the extraction process is put forward. It can provide general method for information extraction of product; namely, extracting pattern of sub-goal is combined with attribute patterns of sub-goal. Matching value is used to denote the matching degree between pattern of sub-goal and text section in the extracting process. The method of extraction of text information for product design is another innovative point.3. The information collection system for product design is developedAccording to the thinking proposed, the information collection system for product design is developed by programming computer. The feasibility of the thinking proposed is verified and accuracy is proved by the developed system.
