摘　　要：针对制造信息化过程中,企业只能从固定格式的标题栏和明细表中提取信息的不足,通过分析标题栏、明细表在工程图样中的结构特征和数据存储特点,使其按拓扑结构进行分类,并存入数据库。利用不同语义的数据在拓扑结构相同的表格中分布相似的特性,从数据库中检索与目标数据表格有相同拓扑关系的记录,并按记录中各语义数据的分布情况来提取目标数据表的信息,从而有效地解决了任意格式的数据表中零部件信息的提取问题。To overcome the shortcoming of datum which can be only extracted from stated forms, the pal：er analyzes the frames in the engineering drawings and the characteristics of storing data in title bar and part list, According to the structure, variant forms are distinguished and put into the database. A new effective met!rod is proposed, which make it easy to extract part information from rake forms. In this way, the structure of a rake form is searched in database. Since the data distribution is similar informs which have same frames, the rake form＇s information can be discerned based on the data distribution of a table with the same structure of the form in database.
