Knowledge Information Systems Course

SATOH Tetsuji (Professor)  Best Faculty Member 2014 (Research)

Theme : Information Access, Mapping the Knowledge and Community Analysis, and Contents Engineering

The spread of the Internet has accelerated the transmission of personal information transmission and created a new environment where we can access the information anytime. In this environment, content is composed of fragmentary information written by many writers and related mutually. I study the field of data engineering; examples are Information Access Technology, which describes the structure of the intricately related information network as knowledge and accesses it easily, component technologies to build participatory digital libraries or map technology of knowledge space adapted to individuals and situations, and the elucidation of formation and a change of the author community.

MATSUMOTO Makoto (Professor)  Chancellor, Faculty of Library, Information and Media Science

Theme : Computational Physics, and Scientific Visualization

The focus is on the theoretical study of condensed matter physics and development of the band calculation systems. For example, following subjects are studied:
1)Computer simulations for magnetic materials
2)Scientific visualization for the theoretical results
3)Theoretical study of the magnetic Compton profile and the positron annihilation radiation

MIDORIKAWA Nobuyuki (Professor)  

Theme : Organization of Knowledge,Organization of the Resources of Knowledge, and Classification

When people communicate knowledge to others, they organize the information in some manner. For instance, when people write a book or create Web pages, they consider the component. To be able to search for targets among knowledge resources, the resources must be organized. For example, it is easy to search if the knowledge is classified and arranged. I study the methods of organizing knowledge and knowledge resources.

MIZUSHIMA Eiji (Professor)  

Theme : Museology, Museum Informatics, Digital Archival Studies

Firstly, one of my research themes is the information analysis of museum data, archival data, and collection of libraries, including architectural heritages, world heritages and intangible heritages. Through these researches, secondly, my central theme goes to the new theme of the digitalization of description and documentation. The aim of study is the systematization of the knowledge resources in the classification methodology, visualization, the details of description of the cultural heritage in the historical context and the metadata of the electronic catalog.

MORITSUGU Shuichi (Professor)  

Theme : Computer Algebra System, Algorithms, and Mathematical Knowledge

Algorithms and the applications of computer algebra are studied. Computer algebra is that part of computer science that designs, analyzes, implements, and applies algebraic algorithms. For example, the following subjects are studied: (1) Solving systems of algebraic equations; (2) Symbolic computation of linear algebra; and (3) Implementing modular method algorithms

UDA Norihiko (Associate Professor)  

Theme : Digital Library, Sharing of Information Resources, and Elucidation of Knowledge Phenomena

The objective of the College of Knowledge and Library Sciences, School of Informatics is “The elucidation of a knowledge phenomenon.” We acquire knowledge from teachers or books, although there are many things that seem natural but are not comprehended. An example is the mechanism of communicating knowledge—what kind of “knowledge” we share when we use the “records” saved in the library or the Web. I study the technology directly linked to a knowledge phenomenon through the construction of the information system for sharing information resources. The digital library is the advanced social framework that manages the transfer and sharing of knowledge.

SAKAGUCHI Tetsuo (Associate Professor)  Chief, Knowledge Information Systems Course

Theme : Anti-spam Technologies for E-mail, Technologies of Applications on the Next-Generation Internet, and the Development of Systems which Boost the Storing and Sharing of Information

On the Internet, the opportunities and methods of getting and transmitting information are increasing but people have not yet been able to master most of them. In e-mail communication, it is essential to sift out spam from important e-mail messages. We can also use the Internet for wide-ranging purposes, not only in accessing the next-generation WWW such as WEB2.0. Thus, I study technical developments that enable humans to store and share information easily for proper purposes through the Internet.

SEKI Yohei (Associate Professor)  

Theme : Information Access, Natural Language Processing, and Communication Support

My research interests lie in the area of information access technologies (IAT) from texts, such as news, the Web, etc.—in particular, sentiment analysis, summarization, and multilingual application. My recent work includes collaborative annotation technologies based on collective intelligence, cross-media (or cross-document genre) IAT, and evaluations on IAT.

SUZUKI Nobutaka (Associate Professor)  

Theme : XML, Structured Documents,and Algorithms

Structured documents, such as XML and HTML, have become the de facto standard data format on the Web and have been spreading rapidly. On the other hand, a number of important problems on schema languages (e.g., DTD, W3C XML Schema) and query languages (e.g., XPath) have been shown to be intractable. One of my research interests is to find efficient algorithms for solving such intractable problems (e.g., identifying subclasses of problems that can be solved efficiently).

TAKAKU Masao (Associate Professor)  

Theme : Information Retrieval, Information Behavior, and Digital Library

My research area is information retrieval and information integration systems. Recent research explores an effective methodology on creating, disseminating, managing and providing digital documents, and develops an user study based approach on how people seek documents and learn from them.

TEZUKA Taro (Associate Professor)  

Theme : Information Retrieval, and Statistical Language Models

I am working on statistical language models that uncover the semantic structure of a large document set by applying machine learning techniques. Such information can be utilized to improve information retrieval and text analysis systems. I am also working on creating new probabilistic models and machine learning methods.

TOKII Maki (Assistant Professor)  

Theme : Computational Physics, and Computer Simulation

“Magnetic materials” are applied to various aspects. An example is the “storage medium,” which records various data (information), such as letters, numeral values, images and sound, and the parts of the machine. My research interest is the theoretical calculation of magnetic materials.

MATSUMURA Atsushi (Assistant Professor)  

Theme : Knowledge Information Retrieval System, The Knowledge Excavation from Information, Analysis of Users Demand

The bigger the volume of information, the more important it is to be able to cull what is useful. I thus study the methods of finding and organizing knowledge from various sources, the relationship between situations and the demand, and the aim of utilizing the knowledge information retrieval systems that connect the people’s demand and the knowledge that is omnipresent in society.

WAKABAYASHI Kei (Assistant Professor)  

Theme : Statistical Machine Learning, Dialogue System, Social Media Analysis

My main research interest is theory and fundamental algorithms of Bayesian statistical models that propel advanced machine learning technologies. I also work on the applications of the Bayesian models, including dialogue systems that correctly recognize user's intent, and social media analysis to automatically discover knowledge about events in real-world.

BARYSHEV Eduard (Assistant Professor)  

Theme : History of International Relations, Comparative Social History, Archival Studies

My research interests concern primarily the history of international relations, the history of Eurasia and the history of the East Asia in modern times. At the same time I continue to study about different archival collections of the world, from the viewpoint of archival science. The research topic I am especially interested in is ‘archives and historical consciousness in different cultures in the Information Age’.
