This book contains the proceedings of the International Conference on Knowledge Engineering and Ontology Development – KEOD 2012, which was sponsored by the Institute for Systems and Technologies of Information, Control and Communication (INSTICC) and held in Barcelona, Spain. KEOD 2012 was organized in cooperation with the Association for the Advancement of Artificial Intelligence (AAAI). The main objective of the International Conference on Knowledge Engineering and Ontology Development 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 Engineering and Ontology Development both theoretically and in a broad range of application fields. Knowledge Engineering (KE) refers to all technical, scientific and social aspects involved in building, maintaining and using knowledge-based systems. KE is a multidisciplinary field, bringing in concepts and methods from
several computer science domains such as artificial intelligence, databases, expert systems, decision support systems and geographic information systems. From the software development point of view, KE uses principles that are strongly related to software engineering. KE is also related to mathematical logic, as well as cognitive science and socio-cognitive engineering where the knowledge is produced by humans and is structured according to our understanding of how human reasoning and logic works. Currently, KE is gradually more related to the construction of shared conceptual frameworks, often designated as ontologies. Ontology Development (OD) aims at building reusable semantic structures that can be informal vocabularies, catalogs, glossaries as well as more complex finite formal structures representing the entities within a domain and the relationships between those entities. Ontologies, have been gaining interest and acceptance in computational audiences: formal ontologies are a form of software, thus software development methodologies can be adapted to serve ontology development. A wide range of applications is emerging, especially given the current web emphasis, including library science, ontology-enhanced search, e-commerce and business process management. As always KEOD 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 KDIR - International Conference on Knowledge Discovery and Information Retrieval and KMIS - International Conference on Knowledge Management and Information Sharing. The joint conference, IC3K received 347 paper submissions from 59 countries, which demonstrates the success and global dimension of this conference. From these, 44 papers were published as full papers, 88 were accepted for short presentation and another 60 for poster presentation. These numbers, leading to a “full-paper” acceptance ratio of about 13% and an oral paper acceptance ratio close to 38%, show the intention of preserving a high quality forum for the next editions of this conference. 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 KEOD topic areas. Moreover, the conferences also featured a number of keynote lectures delivered by internationally well known experts, namely Daniel O'Leary (University of Southern California, United States), Sophia Ananiadou (University of Manchester, United Kingdom), Alfred Inselberg (Tel Aviv University, Israel), Peter F. Patel-Schneider (United States) and Florian Michahelles (ETH Zürich, Switzerland), thus contributing to increase the overall quality of the conferences and to provide a deeper understanding of the conferences interest fields. Workshops provide interactive forae 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 2012 namely: 3rd International Workshop on Software Knowledge – SKY (chaired by Iaakov Exman, Juan Llorens and Anabel Fraga). The conference was also complemented with a special session, the Special Session on Enterprise Ontology – SSEO (chaired by Jan Dietz). 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. We trust that you will find these proceedings interesting and to be a helpful reference in the future. All presented papers will be submitted for indexation by Thomson Reuters Conference Proceedings Citation Index (ISI), INSPEC, DBLP and EI (Elsevier Index), 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. Also, a post-conference special issue of the Wiley Journal "Intelligent Systems in Accounting, Finance and Management" is planned for publication of an extended version of a restricted number of original high quality papers presented during the KEOD 2012. 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, also 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.
