Istella Learning to Rank dataset

Exciting news!!! From the istella tech blog (here): “istella is glad to release the Istella Learning to Rank (LETOR) dataset to the public, used in the past to learn one of the stages of the Istella production ranking pipeline. To the best of our knowledge, this is the largest publicly available LETOR dataset, particularly useful for large-scale experiments on the efficiency and scalability of LETOR solutions.”

International Workshop on Tourism Facilities (TF’12)

Hi all,

together with Ranieri Baraglia and Rossano Venturini, two colleagues at ISTI-CNR, we are organizing the first International Workshop on Tourism Facilities 2012  (TF’12).
It will focus on advances in systems and techniques enabling tourism facilities. The workshop is co-located with the 2012 IEEE/WIC/ACM International Conference on Web Intelligence (WI 2012) and it will be held the December 4th, 2012 in Macau, (China). It would be an interactive forum for researchers ranging from data mining, information retrieval, natural language processing, machine learning to interface engineering to discuss common problems and to identify new solutions of this emerging scenario.

Are you interested!? Here the link: http://tf.isti.cnr.it
