As one of the most disruptive technologies of the last decades, the Web was responsible for drastic technological, economical, and even social developments: today it forms the main source of information as well as entertainment anytime, anywhere. It connects people via social platforms, but is also the most influential infrastructure for commerce and business. To facilitate this, the tight integration of information retrieval technology and innovative data management techniques was necessary. Since then, the Web has prospered, diversified and developed into the largest and omnipresent information source and, what is more, a meaningful knowledge space. However, the basic interaction and navigation methods addressing text-based content on the Web as well as in the underlying databases and information systems have been progressing comparatively slowly. Even modern systems mostly rely on techniques for retrieving, finding, and navigating information that were developed decades ago. Techniques like e.g. SQL queries, hierarchical categorization, list browsing, keyword-based filtering, or simple IR-style keyword searches are still predominant as sole method of accessing content or services. Given the semantics behind and the connections between data items on the Web, there is however a wide variety of applicable methods for improving and personalizing access paradigms. Focused information extraction working hand in hand with domain-centered conceptual models for representation is already beginning to change query processing. This talk focuses on such alternative approaches for user-centered information access going beyond categories and keywords. It introduces querying with concepts based on individual user perceptions or sentiments, using crowd-sourcing for query processing, or employing analogical reasoning for the intuitive communication of information needs. 講演者情報： Prof. Dr. Wolf-Tilo Balke Institute for Information Systems (IfIS) Technische Universität Braunschweig http://www.ifis.cs.tu-bs.de/staff/balke Research Interests: Databases, Query Processing, Personalization, Information Systems & Digital Libraries Short CV: Wolf-Tilo Balke currently holds the chair for information systems at Technische Universität Braunschweig, Germany, and serves as a director of L3S Research Center at Leibniz Universität Hannover, Germany. Before, he was the associate research director of L3S and a research fellow at the University of California at Berkeley, USA. His research is in the area of databases and information service provisioning, including personalized query processing, retrieval algorithms, preference-based retrieval and ontology-based discovery and selection of services. Wolf-Tilo Balke is the recipient of two Emmy-Noether-Grants of Excellence by the German Research Foundation (DFG) and the Scientific Award of the University Foundation Augsburg, Germany. He has received his BSc and MSc degree in mathematics and a PhD in computer science from University of Augsburg, Germany. Dr. Christoph Lofi National Institute of Informatics http://www.christoph-lofi.net Research Interests: Information Systems, Semantic Query Processing, Crowd Sourcing, Personalization Short CV: Christoph Lofi is currently a post-doctoral researcher at National Institute of Informatics, Tokyo, Japan. His research focus is on exploring novel database query paradigms, incorporating crowd-sourcing into information systems research, and query personalization. Before his time at NII, he worked as a post-doctoral researcher at Technische Universität Braunschweig, Germany. He is a recipient of a FIT grant by the German Academic Exchange Service (DAAD). 2005 he graduated in computer science at Technische Universität Kaiserslautern, Germany, where he also worked at the Fraunhofer Institute for Experimental Software Engineering (IESE), before moving to the Collaborative Software Development Laboratory at University of Hawaii, Honolulu, USA. In 2006 he started PhD studies at the L3S Research Center, Hannover, Germany and from 2008 worked at Technische Universität Braunschweig, Germany where he received his PhD in 2011. −−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−− 横田 治夫 〒152-8552 東京都目黒区大岡山 2-12-1 東京工業大学 大学院 情報理工学研究科 計算工学専攻 TEL: (03) 5734-3505 (直通)、 FAX: (03) 5734-3504 email: yokota@cs.titech.ac.jp −−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−−
