Abstract

The invention discloses a microblog text level subject finding method based on seed words. The method comprises the following steps: acquiring data information from the internet, wherein the data information comprises microblog texts; analyzing the microblog texts to acquire a seed word cluster serving as priori knowledge; conducting level subject clustering on the microblog texts to generate a level subject model; integrating the priori knowledge to the level subject model to find level subjects of the microblog texts. By means of the microblog text level subject finding method based on seed words, the level subjects and subject distribution of the texts can be fast extracted from the microblog texts, and the level granulation relation between the released subjects is conveniently found. The invention further provides a microblog text level subject finding system based on the seed words.

Description
