This volume contains the proceedings of the International Conference on Knowledge Discovery and Information Retrieval (KDIR 2010), sponsored by the Institute for Systems and Technologies of Information Control and Communication (INSTICC) in cooperation with the Association for the Advancement of Artificial Intelligence (AAAI) and the Workflow Management Coalition (WfMC). The purpose of the International Conference on Knowledge Discovery and Information Retrieval 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. 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. 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 one of three integrated conferences that are co-located and constitute the International Joint Conference on Knowledge Discovery, Knowledge Engineering and Knowledge Management (IC3K). The other two component conferences are KEOD (International Conference on Knowledge Engineering and Ontology Development) and KMIS (International Conference on Knowledge Management and Information Sharing). The joint conference, IC3K, has received 369 paper submissions from more than 42 countries in all continents. 38 papers were published and presented as full papers, i.e. completed work, 89 papers reflecting work-in-progress or position papers were accepted for short presentation, and another 86 contributions were accepted for poster presentation. These numbers, leading to a “full-paper” acceptance ratio of about 10% and a total oral paper presentations acceptance ratio close to 34%, show the intention of preserving a high quality forum for the next editions of this conference. The technical program of the joint conference includes a panel and five invited talks delivered by internationally distinguished speakers, namely: Edwin Diday (CEREMADE, Université Paris Dauphine, France), Rudi Studer (Karlsruhe Institute of Technology (KIT), Germany), Joydeep Ghosh (University of Texas at Austin, U.S.A.), Oscar Pastor (Universidad Politécnica de Valencia, Spain) and Alain Bernard (Ecole Centrale de Nantes, France). Their participation has positively contributed to reinforce the overall quality of the Conference and to provide a deeper understanding of the field of Knowledge Discovery, Knowledge Engineering and Knowledge Management. The proceedings of the conference will be submitted for indexation by DBLP, INSPEC, Thomson-Reuters Conference Proceedings Citation Index and EI. A book with extended and revised versions of a short list of the selected best papers from the conference will be published by Springer-Verlag in the series of Communications in Computer and Information Science (CCIS). A selection of a few papers will be published in a special issue in the International Journal of Speech Technology (IJST). The program for this conference required the dedicated effort of many people. Firstly, we must thank the authors, whose research and development efforts are recorded here. Secondly, we thank the members of the program committee and the additional reviewers for their diligence and expert reviewing. Thirdly, we thank the keynote speakers for their invaluable contribution and for taking the time to synthesise and prepare their talks. 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. This year, the organization will distribute two paper awards at the conference closing session: the best paper award and the best student paper award. The decision was mainly based on the paper classifications provided by the Program Committee. We wish you all an exciting conference and an unforgettable stay in the city of Valencia and we hope to meet you again next year for the 3rd KDIR, details of which will soon be available at http://www.kdir.ic3k.org.
