This publication constitutes the refereed lawsuits of the thirty third annual ecu convention on info Retrieval examine, ECIR 2011, held in Dublin, eire, in April 2010. The forty five revised complete papers provided including 24 poster papers, 17 brief papers, and six software demonstrations have been rigorously reviewed and chosen from 223 complete learn paper submissions and sixty four poster/demo submissions. The papers are geared up in topical sections on textual content categorization, recommender structures, internet IR, IR evaluate, IR for Social Networks, cross-language IR, IR idea, multimedia IR, IR functions, interactive IR, and query answering /NLP.

The sixteenth-century Reformation is still a desirable and fascinating region of research. The revised version of this unusual quantity explores the highbrow origins of the Reformation and examines the significance of rules within the shaping of background. presents an up-to-date and extended model of the unique, highly-acclaimed version.
This booklet constitutes the refereed court cases of the seventh eu convention on Symbolic and Quantitative methods to Reasoning with Uncertainty, ECSQARU 2003, held in Aalborg, Denmark in July 2003. The forty seven revised complete papers awarded including 2 invited survey articles have been rigorously reviewed and chosen for inclusion within the e-book.

Moreover, they found that using tags alone achieves better performance on topic-speciﬁc and densely labeled document collections. In their experiments, each document had 1,307 tag tokens on average. Motivated by their observation, we are attempting to answer the following question in this work: can we extend the advantage of using only tags on document clustering to more general and large-scale web pages? It turns out the tag-based web document clustering is challenging because most web pages have few annotations.
He developed one of the most commonly used datasets for computing semantic relatedness of words, as well as formulated a methodology for parameterized generation of labeled datasets for text categorization. Evgeniy taught multiple tutorials on computational advertising and organized a number of workshops at top conferences, including a workshop on feature generation and selection for information retrieval at SIGIR, and workshops on the synergy between user-contributed knowledge and research in AI at IJCAI and AAAI.
