Abstract: Consumption intention recognition in microblog is a new research topic in social media. However, existing work mainly focuses on identifying the commercial intention in microblog, literatures engaged in the recognition of consumption target are still sparse. Meanwhile, recognizing consumption target is the key to accurate commercial recommendation. Since the contents in microblog are usually short and informally using of terms, the results of dictionary matching and dependency analysis based methods are not satisfied as the low recall. This paper presents a new method which is based on pseudo relevance feedback by using cross media. This paper firstly analyzes the keywords in consumption intention, then formulates it as queries to submit to the search engine, finally extracts consumer target from the search results. The experimental results are significantly better than those of the baseline methods relying on existing technologies.
