两年来接待WPI检索课题,从最后结果看,有些检查索果很好;有些检索效果一般(检索出一定专利文献,在查全查准上还不够);有检索效果不好(查不到或查的不准)。影响检索效果的因素很多。有些是因为用户对WPI数据库的收藏性质和专利文献的特点不够了解。有些是检索用户不能准确的概括和描述要检索的技术内容。当然,有些是因为接待人员专业范围的限制等等。我们认为要搞好WPI检索,下面几点需要注意和加强: 一、向检索用户充分说明WPI数据库的文献性质、收藏范围以及专利文献与其它文献的异同。有些用户听说河南省科技情报研究所可以进行联机检索,总以为计算机可将国内外一切文献都全部检索出来,实际这是很大的误解。
Two years to receive WPI retrieval subject, from the final results, some of the inspection results are very good; some search results in general (retrieved a certain patent literature, in search of the entire inspection is not enough); search results are not good (not found or Not allowed to check). Many factors affect the search results. Some because of the nature of the user’s collection of WPI databases and the features of the patent literature. Some search users can not accurately summarize and describe the technical content to be retrieved. Of course, some are due to the limited range of reception staff and so on. We think the following points need to be noticed and strengthened in order to do a good job of WPI retrieval: First, to fully reveal the nature of the document, the range of collection and the similarities and differences between the patent documents and other documents to the searching users. Some users have heard that Henan Institute of Scientific and Technical Information can conduct on-line search, always thinking that the computer can retrieve all the documents at home and abroad, which is actually a big misunderstanding.
