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 在非结构化光学数据的结构化处理中，本文提出了一种全新的中文全文汉语自动分词算法：引入上下文相关的词频，结合关键字词典，高效地完成中文汉语自动分词；另对光学文献的专业分类，也提出了一种新的计算机自动分类方法：即通过对增加光学类关键字的光学学科分类属性，计算光学文章中出现的各个所属光学学科类关键字的比例关系，定量地对光学文献进行分类。
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 详细介绍了基于web的光学专业数据库信息检索系统的建立和实现：原始光学信息经过分类后分为结构化光学数据和非结构化光学数据，经过对非结构化光学数据的预处理使其转化为结构化数据，然后将结构化分类光学数据导入光学专业数据库，建立人机交互检索界面，实现基于web的光学数据信息的检索。
