The 27th International Conference on Information Modelling and Knowledge Bases (EJC2017) continues the series of events that originally started as a co-operation initiative between Japan and Finland since 1982. Later, in 1991, the geographical scope of these conferences expanded to cover the whole Europe and other countries in the region. To bring the interest on information modelling and knowledge bases for the region outside Europe and Japan, the EJC2017 conference was for the first time to be organized in Thailand.
In the recent years, information modelling and knowledge bases have become more and more essential because of the drastic growth of data on cyber space. The machine to machine communication in IoT (Internet of Things) implementation can generate unexpectedly large amounts of raw data. The issue has already attracted many research communities in the area of big data storage and analytics. The EJC2017 conference provided a communication place for information exchange and updating the results.
The EJC conferences constitute a world-wide research forum for the exchange of scientific results and experiences achieved in computer science and other related disciplines using innovative methods and progressive approaches. Accordingly, a platform has been established to bring together researchers as well as practitioners to concern information modelling and knowledge bases. The main topics of EJC conferences are focused in the multidisciplinary research of information modelling, conceptual analysis, design and specification of information systems, multimedia information modelling, multimedia systems, ontology, software engineering, knowledge and process management, knowledge bases, cross-cultural communication and context modelling. We also aim at applying new progressive theories. To this end, much attention is paid also to theoretical disciplines including cognitive science, artificial intelligence, logic, linguistics and analytical philosophy.
In order to achieve EJC targets, the international program committee selected 29 papers of 42 submissions for publishing in this book. The selected papers cover the wide range of information modelling, namely the theory of concepts, semantic computing, data mining, context-based information retrieval, ontological technology, image databases, temporal and spatial databases, document data management, software engineering, cross-cultural computing, environmental analysis, social networks, WWW information management, and many others.
The conference could not be a success without the efforts from our colleagues and organizations. In the program committee, reputable researchers devoted a lot of efforts in the review process to select the best papers and create the EJC2017 program. We would like to express our sincere gratitude to their great efforts. Yasushi Kiyoki and Benhard Thalheim conducted the co-chairs of the program committee. Naofumi Yoshida in program coordination managed the review process and the conference program. Virach Sornlertlamvanich, Petchporn Chawakitchareon, Aran Hansuebsai, and their colleagues managed the conference venue and the local arrangement. Professor Hannu Jaakkola took care of general organizational matters necessary for annually organizing the conference series and, moreover, arranging the conference proceedings in the form of a book to be printed by IOS Press Amsterdam. The conference was supported by the SIIT at Thammasat University, Chulalongkorn University, Khon Kaen University, Burapha University, Keio University, the Tampere University of Technology and Christian Albrechts University at Kiel. We gratefully appreciate the efforts of all the supporters
