New York : ACM Press. pp. 688-695.
    Language Modeling (LM) has been successfully applied to Information Retrieval (IR). However, most of the existing LM approaches only rely on term occurrences in documents, queries and document collections. In traditional ...
  • Towards a belief-revision-based adaptive and context-sensitive information retrieval system.

    LAU, R. Y. K., BRUZA, P. and SONG, D., 2008. Towards a belief-revision-based adaptive and context-sensitive information retrieval system. ACM Transactions on Information Systems, 26 (2), article 8.
    In an adaptive information retrieval (IR) setting, the information seekers' beliefs about which terms are relevant, or non-relevant, will naturally fluctuate. This article investigates how the theory of belief revision ...
  • Towards context-sensitive information inference. 

    Song, Dawei; Bruza, Peter D. (Wiley http://dx.doi.org/10.1002/asi.10213, 2003-02)
    SONG, D. and BRUZA, P. D., 2003. Towards context-sensitive information inference. Journal of the American Society for Information Science and Technology, 54 (4), pp. 321-334.
    Humans can make hasty, but generally robust judgements about what a text fragment is, or is not, about. Such judgements are termed information inference. By drawing on theories from non-classical logic and applied cognition, ...
  • Towards operational abduction from a cognitive perspective.
