    • A measure of similarity between two documents is computed. In computing the measure of similarity, a first list of rated keywords extracted from the first document and a second list of rated keywords extracted from the second document are received. The first and second lists of keywords are used to determine whether the first document forms part of the second document using a first computed percentage indicating what percentage of keyword ratings in the first list also exist in the second list. A second percentage is computed that indicates what percentage of keyword ratings along with a set of their neighboring keyword ratings in the first list that also exist in the second list when the first percentage indicates that the first document is included in the second document. The first percentage is used to specify the measure of similarity when the second percentage is greater than the first percentage.
    • 计算两个文档之间的相似性度量。 在计算相似性度量时,接收从第一文档提取的评级关键字的第一列表和从第二文档提取的第二列表。 关键字的第一和第二列表用于确定第一文档是否使用第一计算百分比形成第二文档的一部分,该百分比指示第二列表中还存在第一列表中的关键字评级的百分比。 计算第二百分比,其指示当第一百分比指示第一个文档包括在第二个文档中时,关键字评级的百分比以及第一个列表中也存在于第二个列表中的一组相邻关键字评级的百分比。 第一个百分比用于指定第二个百分比大于第一个百分比时的相似度度量。
