Embodiment Construction

[0045] The present invention is described below in conjunction with accompanying drawing:

[0046] see figure 1 A flow chart of a blog hierarchical classification tree construction method based on tag clustering of the present invention, combined with figure 2 A schematic diagram of the calling relationship between the algorithms of each part in a method for constructing a blog hierarchical classification tree based on tag clustering in the present invention. As shown in the figure, the blog hierarchy construction algorithm is a recursive call process. The first step of this algorithm is: initialize and input the pre-defined blog hierarchy classification tree and the adjacency matrix constructed from all tag relationship data; the second step: The tag clustering algorithm will be called to cluster the tag relationship data, thereby generating several tag clusters; the third step: using the topic generalization algorithm to extract one or more key tag words as the theme of ea...

Abstract

The invention relates to a method for constructing a blog hierarchical classification tree based on tag clustering. The method comprises the following steps: firstly, initializing and inputting a predefined blog hierarchical classification tree and an adjacency matrix which is constructed by tag relational data; secondly, calling a tag clustering algorithm to cluster the tag relational data so as to generate a plurality of tag clusters; thirdly, applying a theme generalization algorithm to extract one or a plurality of key tag words from each tag cluster as a theme of the cluster; fourthly, recursively calling the second step and the third step when the cluster can be further clustered; fifthly, constructing a new hierarchy and increasing a new theme node in the blog hierarchical classification tree after each recursive call is completed; sixthly, outputting a constructed blog hierarchical classification tree after the recursive terminal condition is completely fulfilled. The method is provided by aiming at searching, exploiting, browsing and other problems of blog data, can quickly organize the theme hierarchical relation of mass blog data, and has higher efficiency and accuracy.

Description

technical field [0001] The invention relates to a technology for constructing a blog topic hierarchy, in particular to a method for constructing a blog hierarchical classification tree based on tag clustering. Background technique [0002] Blog is a blog, which is a popular personal media. It carries a large amount of valuable information, and its status in the Internet is becoming more and more important, and it has become an indispensable part of people's daily life and work. However, because the information characteristics of blogs and traditional webpages are very different, how to carry out targeted retrieval and deeper mining and utilization of information in blogs has become a hot spot in the current Internet application research. [0003] In solving problems such as information retrieval, mining and browsing of blogs, it is an important link to extract topics from log content. Blog logs contain a variety of topics, and it is necessary to distinguish different topic...
