Research on Chinese microblog´s semantic expansion model based on specific context

Analyzing and researching microblog text and microblog context, we propose a Chinese microblog´s semantic expansion model based on specific context. Firstly, on the basis of analysis of microblog type, microblogs are classified into six categories: information-publish microblogs, journaling microblogs, sharing microblogs, forwarding microblogs, commentary microblogs and interactive microblogs. For information-publish microblogs, we propose a Chinese microblog´s semantic expansion model based on specific context. Select forwarding comment as specific context. Microblog´s effective forwarding information is added to microblog text for supplementing the microblog´s semantics and improving the problem of data sparseness. The results of microblog classification performance evaluation show that the model enhances the microblog classification performance.
