A two-stage decision model for information filtering

Li, Yuefeng and Zhou, Xujuan and Bruza, Peter and Xu, Yue and Lau, Raymond Y.K. (2012) A two-stage decision model for information filtering. Decision Support Systems, 52 (3). pp. 706-716. ISSN 0167-9236


Information mismatch and overload are two fundamental issues influencing the effectiveness of information filtering systems. Even though both term-based and pattern-based approaches have been proposed to address the issues, neither of these approaches alone can provide a satisfactory decision for determining the relevant information. This paper presents a novel two-stage decision model for solving the issues. The first stage is a novel rough analysis model to address the overload problem. The second stage is a pattern taxonomy mining model to address the mismatch problem. The experimental results on RCV1 and TREC filtering topics show that the proposed model significantly outperforms the state-of-the-art filtering systems.
