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 been paid to an intuitive but cri... Read More about Robust query-specific pseudo feedback document selection for query expansion..

A latent variable model for query expansion using the hidden Markov model. (2008)
Presentation / Conference
HUANG, Q. and SONG, D. 2008. A latent variable model for query expansion using the hidden Markov model. In Proceedings of the 17th Association for Computing Machinery (ACM) international conference on information and knowledge management (CIKM'08), 26-30 October 2008, Napa Valley, USA. New York: ACM [online], pages 1417-1418. Available from: https://doi.org/10.1145/1458082.1458310

We propose a novel probabilistic method based on the Hid- den Markov Model (HMM) to learn the structure of a Latent Variable Model (LVM) for query language modeling. In the proposed LVM, the combinations of query terms are viewed as the latent variab... Read More about A latent variable model for query expansion using the hidden Markov model..
