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.
