Shen, Yan and Li, Yuefeng and Xu, Yue and Iannella, Renato and Algarni, Abdulmohsen and Tao, Xiaohui (2011) An ontology-based mining approach for user search intent discovery. In: 16th Australasian Document Computing Symposium (ADCS 2011), 2 Dec 2011, Canberra, Australia.
Discovering proper search intents is a vital process to return desired results. It is constantly a hot research topic regarding information retrieval in recent years. Existing methods are mainly limited by utilizing context-based mining, query expansion, and user profiling techniques, which are still suffering from the issue of ambiguity in search queries. In this paper, we introduce a novel ontology-based approach in terms of a world knowledge base in order to construct personalized ontologies for identifying adequate concept levels for matching user search intents. An iterative mining algorithm is designed for evaluating potential intents level by level until meeting the best result. The propose-to-attempt approach is evaluated in a large volume RCV1 data set, and experimental results indicate a distinct improvement on top precision after compared with baseline models.
