In this paper, the research activities of the "Network Technology as Context of Society and as Methodology of Social Science" research group, which consists of three teams, the "Construction and Management of Information Platforms" Team, "Language Policy as a 'Basis of Human Security'" Team, and "Web Social Research Methodology Development: Socio-Semantics" Team, are illustrated. The key concept that the three teams have in common is “language space." "Language space" is a place where messages are exchanged, and also a place where networks are created by language. With regard to the transmission of information, we mean not only face-to-face communication, but also communication that is not face-to-face, where the sender and the receiver are located far apart from each other. The latter has been made possible by the development of IT technology. Based on the idea that "networks involving people, language, and information technology contribute to the building of human security," our group addresses the policy management studies theme of how context should be formed to cultivate practical knowledge.
