A Blog-Profile Based Normalization Strategy for Blog Opinion Retrieval
Zhong Shang-ping · Zhongwen xinxi xuebao · 2010
The goal of Blog Opinion Retrieval is to retrieve the blog units that not only relate to a given query but also comment on the query.Previous works ranked blog units by the opinion strength of a single blog unit.However,since blog is the media expressing the blogger's opinions and feelings,the personality of a blogger could affect the strength of his opinion.Therefore,it is disadvantageous defect to use only a single blog unit to get opinion score while neglecting the blogger's factor.In this paper we build a blogger profile and then present a blogger-profile based normalization strategy for blog opinion retrieval.We apply it to normalize the Blog Opinion Retrieval algorithm based on probabilistic inference model.Experiment results show that the proposed normalization strategy could rank blog units more reasonably and improve the retrieval performance.
