Takaku Laboratory†

Takaku Laboratory is a research group affiliated to College of Knowledge and Library Sciences and Master's and Doctoral Programs in Informatics, its former name was Graduate School of Library, Information and Media Studies, at University of Tsukuba. Takaku Laboratory has been established in 2013.

The laboratory's research spans the fields of information-seeking behavior, information organization, digital libraries, and information retrieval. A key focus is on modeling information systems that intelligently support the mediation between users' information needs and documents. The laboratory employs advanced methodologies, such as the use of semantic web and knowledge graph technology, in the structuring and data modeling of knowledge information. Other areas of research include the development of information access methods, and the process and evaluation of human information search results.

In recent years, the laboratory has been conducting research in a wide range of areas, including methods for understanding the knowledge transformation of searchers in information-seeking behavior, metadata information systems based on Linked Open Data (LOD), and the state of academic information distribution in the web age. For more information, please see the list of publications.
