Foreword: This volume contains the proceedings of the Sixth International Conference on Knowledge Discovery and Information Retrieval (KDIR 2014) which was sponsored by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) and held in Rome, Italy. KDIR was organized in cooperation with the AAAI - Association for the Advancement of Artificial Intelligence, iKMS - Information & Knowledge Management Society, ERCIM - European Research Consortium for Informatics and Mathematics, ACM SIGMIS - ACM Special Interest Group on Management Information Systems and ACM SIGART - ACM Special Interest Group on Artificial Intelligence. The main objective of the International Conference on Knowledge Discovery and Information Retrieval is to provide a point of contact for scientists, engineers and practitioners interested in the scientific and technical advancement of methodologies and technologies for Knowledge Discovery and Information Retrieval both theoretically and in a broad range of application fields. 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. The primary focus of KDIR is to provide a major forum for the scientific and technical advancement of knowledge discovery and information retrieval. As always KDIR is one of the 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 are KEOD - International Conference on Knowledge Engineering and Ontology Development and KMIS - International Conference on Knowledge Management and Information Sharing. KDIR 2014 received 100 paper submissions from 37 countries in all continents, of which 14% were presented as full papers. The high quality of the papers received imposed difficult choices in the review process. To evaluate each submission, a double blind paper review was performed by the Program Committee, whose members are highly qualified independent researchers in the KDIR topic areas. Moreover, the conference also featured a number of keynote lectures delivered by internationally well known experts, namely Domenico Talia (University of Calabria and ICAR-CNR, Italy), Sonia Bergamaschi (DIEF - University of Modena and Reggio Emilia, Italy), Michele Missikoff (CNR and Polytechnic University of Marche, Italy), Wil Van Der Aalst (Technische Universiteit Eindhoven, Netherlands), Wim Van Grembergen (University of Antwerp, Belgium) and Marie-Jeanne Lesot (Université Pierre et Marie Curie - LIP6, France), thus contributing to increase the overall quality of the conferences and to provide a deeper understanding of the conferences interest fields. Workshops provide interactive fora that allow for a more in-depth discussion of particular areas within the scope of the conference. We would like to thank the workshop chairs for their collaboration in providing this added-value satellite event of IC3K 2014 namely: 5th International Workshop on Software Knowledge – SKY (chaired by Iaakov Exman, Juan Llorens, Anabel Fraga and Juan Miguel Gómez). The conference was also complemented with a special session, the Special Session on Text Mining - SSTM (chaired by Ana Fred) To recognize the best submissions and the best student contributions, awards based on the best combined marks of paper reviewing, as assessed by the Program Committee, and the quality of the presentation, as assessed by session chairs at the conference venue, were conferred at the closing session of the conference. All presented papers will be submitted for indexation by Thomson Reuters Conference Proceedings Citation Index (ISI), INSPEC, DBLP, EI (Elsevier Index) and Scopus, as well as being made available at the SCITEPRESS Digital Library. Additionally, a short list of presented papers will be selected to be expanded into a forthcoming book of IC3K Selected Papers to be published by Springer Verlag. Building an interesting and successful program for the conference required the dedicated effort of many people. We would like to express our thanks, first of all, to all authors including those whose papers were not included in the program. We would also like to express our gratitude to all members of the Program Committee and auxiliary reviewers, who helped us with their expertise and valuable time. Furthermore, we thank the invited speakers for their invaluable contribution and for taking the time to synthesize and prepare their talks. Moreover, we thank the workshop and special session chairs whose contribution to the diversity of the program was decisive. Finally, we gratefully acknowledge the professional support of the INSTICC team for all organizational processes. (More)
