A Vertical Search Engine for Energy Conservation and Environmental Protection

For most of the current search engines, the difference of their returned results are only because of the different keywords, i.e. for the same keywords used for searching, the same results will be returned. In fact, different users may have different search purposes even if they use the same keywords. In this paper, we propose a vertical search engine in the domain of energy conservation and environmental protection. We construct the vertical search engine based on the special domain models and the user motivation models, so that the efficiency and accuracy rate of information retrieval can be improved. Experiments show that the returned results by the vertical search engine can better meet the requirements of the users.
