The invention provides a model and a system for expanding microblog semanteme, belongs to the field of text information processing and particularly relates to a method and a system for classifying microblog and expanding the microblog semanteme. The invention relates to the model for expanding the microblog semanteme based on forwarding and commenting. Firstly, the microblog is divided into six types based on analysis on microblog user types: information publishing type microblog, log type microblog, sharing type microblog, forwarding type microblog, commenting type microblog and interactive type microblog; then, the model for expanding the microblog semanteme based on forwarding and commenting is provided by taking the information publishing type microblog as a research object, effective commenting information of the microblog is added in a microblog text so as to supplement the microblog semanteme, and the problem of sparse microblog data is improved. According to the model for expanding the microblog semanteme based on forwarding and commenting, disclosed by the invention, the classification performance of the microblog is increased.
