By ChengXiang Zhai (auth.), Giambattista Amati, Fabio Crestani (eds.)

This booklet constitutes the refereed complaints of the 3rd foreign convention at the conception of knowledge Retrieval, ICTIR 2011, held in Bertinoro, Italy, in September 2011. The 25 revised complete papers and thirteen brief papers awarded including the abstracts of 2 invited talks have been conscientiously reviewed and chosen from sixty five submissions. The papers disguise issues starting from question growth, co-occurence research, consumer and interactive modelling, approach functionality prediction and comparability, and probabilistic ways for rating and modelling IR to subject matters on the topic of interdisciplinary techniques or functions. they're prepared into the next topical sections: predicting question functionality; latent semantic research and observe co-occurrence research; question growth and re-ranking; comparability of knowledge retrieval platforms and approximate seek; likelihood score precept and choices; interdisciplinary methods; consumer and relevance; consequence diversification and question disambiguation; and logical operators and descriptive approaches.

Example text

All predictors discussed above are based on a single retrieval (if at all) used to create a pseudo (in)effective ranking. Alternatively, fusion of multiple rankings can be used to produce a pseudo effective ranking [8]. Indeed, the merits of fusion, in terms of retrieval effectiveness, have been acknowledged [9]. Pearson’s correlation between the given result list and that produced by fusion served for query-performance prediction [8]. Clearly, this prediction approach is a specific instance of our framework (with α(q) = 1 and β(q) = 0).
