    • A system and method for providing efficient document scoring of concepts within a document set is described. A frequency of occurrence of at least one concept within a document retrieved from the document set is determined. A concept weight is analyzed reflecting a specificity of meaning for the at least one concept within the document. A structural weight is analyzed reflecting a degree of significance based on structural location within the document for the at least one concept. A corpus weight is analyzed inversely weighing a reference count of occurrences for the at least one concept within the document. A score associated with the at least one concept is evaluated as a function of the frequency, concept weight, structural weight, and corpus weight.
    • 描述了用于提供文档集合内的概念的有效文档评分的系统和方法。 确定从文档集中检索到的文档内的至少一个概念的发生频率。 分析了一个概念权重,反映了文档中至少一个概念的含义的特异性。 分析结构重量,反映基于至少一个概念的文档内的结构位置的重要程度。 分析语料库重量,对文档中的至少一个概念进行反向称量事件的引用计数。 与至少一个概念相关联的分数被评估为频率,概念权重,结构重量和语料库权重的函数。

    • A system and method for determining a spatial arrangement of thematically-related clusters is provided. A convex cluster is selected from a set of convex clusters, which each include shared concepts and terms. A center of mass is determined for the selected convex cluster. An anchor point including at least one open edge formed at an intersection of a segment measured from the center of mass and an edge of the convex cluster is located. One or more of the remaining convex clusters in the convex clusters set is selected. The one or more remaining convex clusters are arranged with a center of mass originating outside of the anchor point and on the segment of the selected convex cluster. Overlap of the arranged convex clusters is limited. The arranged convex clusters are displayed.
    • 提供了一种用于确定与主题相关的群集的空间排列的系统和方法。 从一组凸集群中选择一个凸簇,每个凸集包括共享概念和术语。 确定所选凸群的质心。 定位点包括至少一个开口边缘,该至少一个开口边缘形成在从质心中测量的区段与凸起群的边缘的交点处。 选择凸群集中剩余的一个或多个凸簇。 所述一个或多个剩余的凸起簇以源于定位点外侧和所选择的凸起群的段上的质心设置。 排列的凸集的重叠是有限的。 显示排列的凸群。
