Nontraditional Database Systems is the fifth volume in the Advanced Information Processing Technology series. It brings together the results of research carried out by the Japanese database research community in the field of nontraditional database systems. The book examines nontraditional types of applications, data types, systems and environments together with high-performance architecture to support nontraditional applications, such as web mining, data engineering and object processing.

Provides recent developments of information organization technologies that have become crucial not only for data mining applications and information visualization, but also for treatment of semistructured data, spatio-temporal data and multimedia data that are not necessarily stored in conventional DBMSs. The book presents: semistructured data addressing XML, query languages and integrity constraints, focusing on advanced technologies for organizing web data for effective retrieval; multimedia database organization emphasizing video data organization and data structures for similarity retrieval; technologies for data mining and data warehousing; index organization and efficient query processing issues; spatial data access and indexing; and organizing and retrieval of WWW and hypermedia.

Information Organization and Databases: Foundations of Data Organization is a resource for database practitioners, database researchers, designers and administrators of multimedia information systems, and graduate-level students in the area of information retrieval and/or databases wishing to keep abreast of advances in the information organization technologies.

This book constitutes the proceedings of the 5th International Conference on Social Informatics, SocInfo 2013, held in Kyoto, Japan, in November 2013. The 23 full papers, 15 short papers and three poster papers included in this volume were carefully reviewed and selected from 103 submissions. The papers present original research work on studying the interplay between socially-centric platforms and social phenomena.

This book constitutes the refereed proceedings of the 345h International Conference on Conceptual Modeling, ER 2016, held in Gifu, Japan, in November 2016. The 23 full and 18 short papers presented together with 3 keynotes were carefully reviewed and selected from 113 submissions.

We would like to welcome you to the proceedings of the workshops held in conjunction with the 23rd International Conference on Conceptual Modeling (ER 2004). The objective of the workshops associated with ER 2004 was to give p- ticipants the opportunity to present and discuss emerging hot topics related to conceptual modeling, thereby adding new perspectives to conceptual mod- ing. To meet the objective, we selected six workshops with topics on conceptual modelingforWebinformationintegration,digitalgovernment,GIS,changem- agement, e-business, and agent technology. Some of these workshopswere brand new while others had been held in conjunction with ER conferences as many as ?ve times. They are: 1. 1stInternationalWorkshoponConceptualModel-DirectedWebInformation Integration and Mining (CoMWIM 2004) 2. 1st International Workshop on Digital Government: Systems and Techno- gies (DGOV 2004) 3. 1st International Workshop on Conceptual Modeling for GIS (CoMoGIS 2004) 4. 3rd International Workshop on Evolution and Change in Data Management (ECDM 2004) 5. 1st International Workshop on Conceptual Modelling for Agents (CoMoA 2004) 6.5th International Workshop on Conceptual Modeling Approaches for E-Business (The Model-Driven Design Value Proposition) (eCOMO 2004) These six workshops received 38, 16, 58, 21, 17, and 13 papers, respectively. Following the philosophy of the ER workshops, the selection of contributions was very carefully carried out in order to keep the excellent standard; 13, 6, 16, 8, 7, and 6 papers were accepted by the six workshops, respectively, with acceptance rates 34%, 37%, 27%, 38%, 41%, and 46%, respectively.

This book constitutes the refereed proceedings of the 7th Asia-Pacific Web Conference, APWeb 2005, held in Shanghai, China in March/April 2005.The 71 revised full papers and 22 revised short papers presented together with 6 keynote papers and 22 invited demo papers were carefully reviewed and selected from 420 submissions. The papers are organized in topical sections on classification and clustering, topic and concept discovery, text search and document generation, Web search, mobile computing and P2P, XML, integration and collaboration, data mining and analysis, Web browsing and navigation, spatial data, stream data processing, Web services, ontologies, change management, personalization, performance and optimization, Web caching, data grid, multimedia, object recognition and information extraction, visualization and user interfaces, and delivery and networks.

This volume contains the proceedings of the ThirdInternational Conference on Deductive and Object-OrientedDatabases. Its central tenet is that the object-oriented anddeductive paradigms for modeling, organizing, and processingdata complement each other, rather than competing, and thatproblems involving massive volumes of complex data can bestbe solved by integrating the best of both approaches. Central questions in the area are:- How do we design a tool that presents the best of theobject-oriented and declarative ideas?- How can the users of this tool express their problems in acombination of declarative and procedural features? The volume includes 29 papers that contribute towardsanswering these questions.

This volume contains the proceedings of the Fifth International Conference on Database Systems for Advanced Applications (DASFAA '97). DASFAA '97 focused on advanced database technologies and their applications. The 55 papers in this volume cover a wide range of areas in the field of database systems and applications - including the rapidly emerging areas of the Internet, multimedia, and document database systems - and should be of great interest to all database system researchers and developers, and practitioners.
