The Department of Library and Information Science was launched in 1967 and is comprised of the three domains of information systems, information media, and information retrieval.

Information systems is a broad concept that includes the entire information infrastructure, and in our Library and Information Science Program we primarily focus on libraries. It includes library-related legal and business issues, service and user community issues, and their cultural and educational impacts on society. Information media refers to scholarly communication research, academic information system research, bibliometrics, and information seeking behaviors with a focus on human cognition and social practices. Keio has a long history of research experience with these fields. Information retrieval takes a holistic perspective of research issues on information retrieval systems and theory, which differs from a traditional engineering approach, and also deals with information organization and databases. Keio also has experience in the advancement of search engines and information resource organization.

Since April 2006, we have offered a PhD program for librarians and other professionals in information service industry. All credits for this program can be fulfilled through evening classes alone.

    Ethnomethodology, Information Behavior, Knowledge Management, Organizational Ethnography

    My central interest is in examining and understanding the practices of people from their perspective, following the interdisciplinary approach of the Ethnomethodology’s Program. More specifically, I am interested in considering issues such as sharing, creating, and handing down knowledge and expertise in organizational settings and communities by examining and understanding how knowledge and expertise is produced and shared in and through visible practices. This has taken on an increasing importance as this expertise sharing often takes place in technology mediated contexts.I have so far conducted fieldwork in a number of organizational settings, including libraries, hospitals, and corporate organizations. A through understanding of an organization's practices allows for a more nuanced view of the important issues which arise from knowledge management efforts and in my research, has resulted in the co-design of services and technology with stakeholders.

    Information Retrieval

    I am interested in the theory and technology of information retrieval, especially statistical techniques for enhancing retrieval performance. More specifically, I have proposed some algorithms for cross-language information retrieval in which the language of a search query is different from that used in the documents being searched. Automatic clustering of documents is another one of my research topics. For example, I have recently conducted experiments using clustering algorithms that generate a tree structure from a large-scale document collection.

    Scholarly Communication, Library and Information Science

    My research subject is scholarly communication in the construction of scientific knowledge through the role of information media. I am especially interested in the transformation of scholarly communication in the digital age, open access movements of research achievement, and the placement of research platforms in the era of open science.

    Information Organization, Information Resource Management

    Pursuing the organization of knowledge and information resources, which aims at organize vast and varied amounts of information resources to be able to satisfy certain requests (or a variety of requests) effectively and efficiently. Cataloging, metadata management, classification, controlled vocabulary (ontology), and retrieval systems are conventional ways to attain such goals in the field, with new approaches and practices also being developed.
