S系统联合Patentics在测量领域的检索应用

Search Application by Combining S System and Patentics in Measurement Field

测量领域相关案件存在IPC分类号分布广泛、关键词难以表达的问题,分类号通常对应IPC分类中的G部、B部、E部等,机械部件关键词表达多种多样,难以准确表达。检索中若不对分类号和关键词扩展,则会导致漏检,若对分类号和关键词盲目扩展,则会出现大量噪声,使得对比文件淹没在上千篇检索结果中,给对比文件筛选造成巨大困难。S系统具有丰富的检索方式,但检索结果需要人为逐篇筛选;而Patentics具有相关度排序的功能,本文联合S系统和Patentics,将S系统的检索结果导入Patentics中排序,有效避免了漏检,同时提高了对比文件筛选效能。

The IPC classification numbers are widely distributed and the keywords are difficult to express in the field of measurement.The classification numbers often correspond to G,B,and E and so on.The keywords of mechanical parts are various and difficult to express accurately.Without expanding the classification numbers and keywords in the search,it will result in the missing of reference documents.On the other way,If the classification numbers and keywords are expanded blindly,there will be a lot of noise,making the reference documents submerged in thousands of search results,which will cause great difficulties to pick the reference documents out.The S system has a rich search methods,but need to peruse the search results one by one to sift out the reference documents;whereas Patentics has the function of relevance ranking.Combining the S system and Patentics to rank the S system's search results in Patentics effectively avoids missing of reference documents and improves the efficiency to pick the reference documents out.
