Abstract: In order to efficiently thread n chronologically ordered documents, a similarity among the n documents is calculated and the similarity is employed to create a similarity matrix using time constraints, and is converted into an adjacency matrix for identifying a relationship among the n documents. By applying this threading method that employs the time constraints, a large quantity of article data can be efficiently threaded in the O(n) order. Users can easily access a large quantity of data and can understand the contents.
