His thesis described probabilistic models for the retrieval, organization, and exploration of large information collections, casting this tasks as statistical queries. The abstract of his thesis ca be found here and the thesis itself here.

Evaluation consistency in iGAs: User contradictions as cycles in partial-ordering graphs

by Francesc Alías, Xavier Llorà, Lluís Formiga, Kumara Sastry, and David E. Goldberg (2006, accepted). IEEE International Conference on Acoustics, Speech, and Signal Processing (ICASSP 2006). May 14-19, 2006. Also as IlliGAL TR No 2005022. Link to the PDF. Abstract Active interactive genetic algorithms (aiGAs) rely on actively optimizing synthetic fitness functions. In interactive genetic algorithms (iGAs) framework, user evaluations provide the necessary input for synthesizing a reasonably accurate surrogate fitness function that models user evaluations or, in other words, his/her decision preferences....
