Information Search Of Optics Database Based On Web

This article briefly presents the development history of optics, and the great contribution made by the advancement of optics in all fields; puts forward a new optic classification means based on some optic classification standard; briefly introduces some concepts of information search, the structure and the process of information search system, and the characteristic of information search based on web, and the information search system's forming and working process based on web. Particularly presents the realization of optic database information searching system based on web: firstly transforming original optic information into structured optic data and unstructured optic data, secondly transforming unstructured optic data into structured data by pretreatment, then putting these structured data into optic database, building up people-computer alternation searching system, finally realizing optic information searching system based on web.In the processing of unstructured optic data pretreatment, this article puts forward a completed new algorithm of automatic Chinese word segmentation based on context: combining Chinese word frequency based on context and keyword dictionary can completes efficiently Chinese word automatic segmentation; and also presents a new computer automatically classification way about optic articles specialty classification: through adding optic subject classification property on optic keywords and computing the proportion of optic keywords in the article, quantificationally classifies optic articles.
