Contributions of Language Modeling to the Theory and Practice of Information Retrieval, We describe a simulation environment which has been developed for the study of theoretical issues in information retrieval. Results obtained from the simulation are presented, which show quantitatively how variance reduction techniques applied to parameter estimation can improve performance for the ad-hoc retrieval task.

Language Models for Topic Tracking,kelihood, likelihood ratio, normalized likelihood ratio, and the related Kullback-Leibler divergence are evaluated in two orientations. Best performance is achieved by the models based on a normalized log-likelihood ratio. Key component of these models is the a-priori probability of a story with respect to a common reference distribution.
