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 ...

    HUANG, Q., SONG, D. and RUGER, S., 2008. Robust query-specific pseudo feedback document selection for query expansion. In: C. MACDONALD, I. OUNIS, V. PLACHOURAS, I. RUTHVEN and R.W. WHITE, eds. Advances in Information Retrieval: 30th European Conference on IR Research, ECIR 2008, Glasgow, UK, March 30-April 3, 2008; Proceedings. Berlin: Springer. pp. 547- 554
    In document retrieval using pseudo relevance feedback, after initial ranking, a fixed number of top-ranked documents are selected as feedback to build a new expansion query model. However, very little at- tention has ...
  • Towards a belief-revision-based adaptive and context-sensitive information retrieval system. 

    Lau, Raymond Y. K.; Bruza, Peter D.; Song, Dawei (ACM http://doi.acm.org/10.1145/1344411.1344414, 2008-03)
    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 ...

    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.
