Method and apparatus for constructing a compact similarity structure and for using the same in analyzing document relevance

Abstract:

A computer-readable medium comprises data structure for providing information about levels of similarity between pairs of N documents. The data structure comprises a plurality of entries of similarity values representing levels of similarity for a plurality of pairs of the documents. Each of the similarity values represents a level of similarity of one document of a given pair relative to the other document of the given pair. The similarity value of each entry is greater than a threshold similarity value that is greater than zero. The plurality of similarity-value entries are fewer than N2−N in number if the similarity values are asymmetric with regard to document pairing, and the plurality of similarity-value entries are fewer than N 2 - N 2 in number if the similarity values are symmetric with regard to document pairing. A method and apparatus for generating the data structure are described.

Abstract(Chinese):

计算机可读介质包括用于提供关于N个文档对之间的相似性级别的信息的数据结构。数据结构包括表示多对文档对象的相似度级的多个相似度条目。每个相似度值表示给定对的一个文档相对于给定对的另一个文档的相似度级别。每个条目的相似度值大于大于零的阈值相似度值。如果相似度值对于文档配对是不对称的，则多个相似值条目数量少于数目中的N2-N，并且多个相似度值条目少于 $N2-如果相似度值对于文档配对，则数字中的2。描述了用于生成数据结构的方法和装置。Public/Granted literature US20070136336A1
