Abstract:

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.
