    • A data compressor including a separating unit configured to separate input data into cross reference data with the reference information between the vertices, and a vertex group including the plurality of vertices with the types and values, and to output data of the vertex group thus separated; a template storing unit configured to store reference information between vertices having a specific pattern, as a template; a template match detecting unit configured to detect a portion matching the template stored in the template storing unit, from the cross reference data separated by the separating unit; and a template replacing unit configured to replace the matched portion detected by the template match detecting unit with the template, in a state in which the reference information between the vertices can be referred to, and to output the replaced cross reference data.
    • 一种数据压缩器,包括分离单元,其被配置为将输入数据与顶点之间的参考信息分离成交叉参考数据,以及包括具有类型和值的多个顶点的顶点组,并输出由此分离的顶点组的数据; 模板存储单元,被配置为在具有特定图案的顶点之间存储参考信息作为模板; 模板匹配检测单元,被配置为从由分离单元分离的交叉参考数据检测与模板存储单元中存储的模板匹配的部分; 以及模板替换单元,被配置为在可以参考顶点之间的参考信息的状态下,用模板替换由模板匹配检测单元检测到的匹配部分,并输出替换的交叉参考数据。

    • A document processing method, including: a collection step of collecting access history of a user; a document similarity computing step of computing a document similarity, which indicates similarity between documents, by one user pattern which indicates a plurality of users who have accessed one document and another user pattern which indicates a plurality of users who have accessed another document, according to the access history collected in the collection step; a keyword weight vector correction step of correcting a keyword weight vector of the one document using the document similarity computed in the document similarity computing step; and an evaluation value calculation step of calculating an evaluation value for input information for searching, based on the keyword weight vector corrected in the keyword weight vector correction step.
    • 一种文件处理方法,包括:收集用户访问历史的收集步骤; 一种文档相似度计算步骤,用于通过指示已经访问一个文档的多个用户的一个用户模式和指示已经访问另一个文档的多个用户的另一用户模式来计算表示文档之间的相似性的文档相似性 收集步骤中收集的访问历史; 关键字权重向量校正步骤,使用在文档相似度计算步骤中计算出的文档相似度来校正一个文档的关键字权重向量; 以及评估值计算步骤,基于在关键字权重向量校正步骤中校正的关键字权重向量来计算用于搜索的输入信息的评估值。
