8th International Workshop on
Information Filtering and Retrieval
10 December 2014
Post Proceedings Call for Chapter is here
Proceedings are now online here
With the increasing availability of data, it becomes more important to have automatic methods to manage data and retrieve information. Data processing, especially in the era of Social Media, is changing users behaviors. Users are ever more interested in information rather than in mere raw data. Considering that the large amount of accessible data sources is growing, novel systems providing effective means of searching and retrieving information are required. Therefore the fundamental goal is making information exploitable by humans and machines.
DART 2014 intends to provide a more interactive and focused platform for researchers and practitioners for presenting and discussing new and emerging ideas. It is focused on researching and studying new challenges in intelligent information filtering and retrieval. In particular, DART aims to investigate novel systems and tools to web scenarios and semantic computing. In so doing, DART will contribute to discuss and compare suitable novel solutions based on intelligent techniques and applied in real-world applications.
Information Retrieval attempts to address similar filtering and ranking problems for pieces of information such as links, pages, and documents. Information Retrieval systems generally focus on the development of global retrieval techniques, often neglecting individual user needs and preferences.
Information Filtering has drastically changed the way information seekers find what they are searching for. In fact, they effectively prune large information spaces and help users in selecting items that best meet their needs, interests, preferences, and tastes. These systems rely strongly on the use of various machine learning tools and algorithms for learning how to rank items and predict user evaluation.
Oral presentations will be 25 minutes long and consist of a 20-minute talk followed by a 5-minute discussion.

In recent years there has been a growing interest in text quantification, the task of estimating the prevalence (or “relative frequency”) of a class in a set of objects whose membership in the class is unknown. Quantification may be seen as a variant of classification, a variant in which the estimation of accuracy should be carried out at the aggregate level rather than, as customary, at the individual level. In this talk I will discuss recent efforts in applying explicit loss minimization to the quantification task. These efforts, which involve the optimization of an inherently non-linear, multivariate loss function, have recently shown to deliver state-of-the-art performance.
Fabrizio Sebastiani has been a Principal Scientist at QCRI-QF since June 2014; from 2006 to then he has been a Senior Researcher at Istituto di Scienza e Tecnologie dell'Informnazione, Consiglio Nazionale delle Ricerche, Italy, from which he is currently on leave; before 2006 he was an Associate Professor at the Department of Pure and Applied Mathematics of the University of Padova, Italy. His main current research interests are at the intersection of information retrieval, machine learning, and human language technologies, with particular emphasis on text classification, information extraction, opinion mining, and their applications. He is an Associate Editor for ACM Transactions on Information Systems (ACM Press) and AI Communications (IOS Press), and a member of the Editorial Boards of Information Retrieval (Kluwer) and Foundations and Trends in Information Retrieval (Now Publishers); of the latter he is also a past co-Editor-in-Chief. He is also a past member of the Editorial Boards of the Journal of the American Society for Information Science and Technology (Wiley), Information Processing and Management (Elsevier), and ACM Computing Reviews (ACM Press). He is the Editor for Europe, Middle East, and Africa, of Springer's “Information Retrieval” book series. He has been the General Chair of ECIR 2003 and SPIRE 2011, and a Program co-Chair of SIGIR 2008 and ECDL 2010; he is the appointed General co-Chair of SIGIR 2016. From 2003 to 2007 he has been the Vice-Chair of ACM SIGIR. He has given several tutorials at international conferences (ECDL 1997, ECDL 1998, ER 1998, WWW 1999, ECDL 2000, COLING 2000, IJCAI 2001, ECDL 2001, ECIR 2014) and summer schools (among which ESSLLI 2003 and ESSIR 2005) on themes at the intersection of machine learning and information retrieval. |
