This book contains the proceedings of the International Conference on Knowledge Discovery and Information Retrieval (KDIR 2011). This conference is sponsored by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) and this year it is hosted by the University PARIS-EST Créteil (UPEC) at the campus of Sénart. KDIR 2011 was held in cooperation with the Association for the Advancement of Artificial Intelligence (AAAI), the ACM Special Interest Group on Management Information Systems (ACM SIGMIS), the LISSI Laboratory and the Information & Knowledge Management Society (IKMS). The primary focus of KDIR is to provide a major forum for the scientific and technical advancement of knowledge discovery and information retrieval. Knowledge Discovery is an interdisciplinary area focusing upon methodologies for identifying valid, novel, potentially useful and meaningful patterns from data, often based on underlying large data sets. A major aspect of
Knowledge Discovery is data mining, i.e. applying data analysis and discovery algorithms that produce a particular enumeration of patterns (or models) over the data. Knowledge Discovery also includes the evaluation of patterns and identification of which add to knowledge. This has proven to be a promising approach for enhancing the intelligence of software systems and services. The ongoing rapid growth of online data due to the Internet and the widespread use of large databases have created an important need for knowledge discovery methodologies. The challenge of extracting knowledge from data draws upon research in a large number of disciplines including statistics, databases, pattern recognition, machine learning, data visualization, optimization, and high-performance computing, to deliver advanced business intelligence and web discovery solutions. Information retrieval (IR) is concerned with gathering relevant information from unstructured and semantically fuzzy data in texts and other media, searching for information within documents and for metadata about documents, as well as searching relational databases and the Web. Automation of information retrieval enables the reduction of what has been called "information overload". Information retrieval can be combined with knowledge discovery to create software tools that empower users of decision support systems to better understand and use the knowledge underlying large data sets. KDIR is integrated in IC3K (International Joint Conference on Knowledge Discovery, Knowledge Engineering and Knowledge Management) a conference formed by three complementary conferences, namely: KMIS (International Conference on Knowledge Management and Information Sharing), KEOD (International Conference on Knowledge Engineering and Ontology Development) and KDIR. The KDIR program includes a special session, on Text Mining (SSTM). The joint conference, IC3K received 429 paper submissions from 59 countries in all continents. To evaluate each submission, a double blind paper review was performed by the Program Committee. After a stringent selection process, 47 papers were accepted to be published and presented as full papers, i.e. completed work, 94 papers reflecting work-in-progress or position papers were accepted for short presentation, and another 81 contributions were accepted for poster presentation. These numbers, leading to a “full-paper” acceptance ratio of about 11% and a total oral paper presentations acceptance ratio close to 33%, show the intention of preserving a high quality forum for the next editions of this conference. IC3K’s program includes panels and five invited talks delivered by internationally distinguished speakers, namely: Jay Liebowitz (University of Maryland University College, U.S.A.), Carole Goble (University of Manchester, U.K.), Mayer Aladjem (Ben-Gurion University of the Negev, Israel), Guus Schreiber (VU University Amsterdam, The Netherlands) and Jan L. G. Dietz (Delft University of Technology, The Netherlands). As in previous editions of the Conference, based on the reviewers’ evaluations and on the quality of presentations, a short list of authors will be selected and invited to submit extended revised versions of their papers for a book that will be published by Springer with the best papers of IC3K 2011. We would like to express our thanks to all participants. First of all, to the authors, whose quality work is the essence of this Conference. Next, we thank to all the members of the program committee and the auxiliary reviewers for their diligence and expert reviewing. We would also like to deeply thank the invited speakers for their excellent contribution in sharing their knowledge and vision. Fourthly, we thank the program chair, Ana Fred, whose collaboration was much appreciated. Finally, special thanks to all the members of the INSTICC team whose collaboration was fundamental for the success of this conference. We wish you all an exciting conference and an unforgettable stay in the city of Paris and we hope to meet you again next year for the 4th KDIR, details of which will shortly be made available at http://www.kdir.ic3k.org.
