Keyword extraction method over blog community
Wei Yang, Yang Zhizhuo · 2016
Existing methods for Blog keyword extraction usually exploit the context in the specified blog. In this paper, we propose to provide a knowledge context by using small number of nearest neighbor blogs to improve keyword extraction performance. Specifically, knowledge context is build by adding several topic related blogs closed to the specified blog, and then the manifold ranking model is used on the knowledge context to make use of both knowledge contained in the specified blog and knowledge contained in the neighbor blogs. Experimental results show that this method can significantly outperform the baseline method, and also obtains improvement over existing method.
