Profession:

Tsurumi University

Education:
Ph.D.(Information and System Science)
M.A.(Linguistics)

Career:
Before starting a career at Tsurumi University, worked at a private company as an editor, director, producer, programmer, and consultant for publishing academical materials and their management, including the project of digitizing rare books in Japan National Diet Library.

Research Fields:
  1. Formal Semantics.
    At a master course, studied meanings of Japaneses Language on Situation Semantics, especially, morphemes appearing on a boundary between propositional sentences which have been treated on logic and discourse statements which have been studied independently of meanings of sentences. To do this, have to collect and process data of discourse descriptions, then started research on markup languages.
  2. SGML/XML
    especially study link-based structured data and hierarchy of meta descriptions.
  3. Digitization of materials for humanities.
    believe that digitizing rare books and manuscripts is an academical research field, which is abandoned by researchers of humanities, especially in Japan.
  4. Data-flow-based Models of Organization
    presuppose that organizations can be defined by a boundary of information concealment. If so, can establish organizations based on not traditional rule-based but data-flow-based models, and contribute to make a new management system of digital information like digitized and born-digital documents.
  5. Theory of Markup Languages
    seek a grand theory of markup languages, which is an important elemental technology for the above all.
  6. Theory of Description
    seek a theory that reflects dynamics of generative aspects of language descriptioins, e.g. a hierarchy of description, a model for an information unit on a physical restrictied space such as a sheet of paper, and a pivotal data format for flexivle data conversion(not one-source-multi-use philosophy, but a stance of one source easily converted into multiple formats).
