Aims

Our Research Direction

Knowledge and Language Computing Laboratory (KaLC Lab) aims at developing computational models of human knowledge and language and apply them to various real-world problems.

Target: Domain Specific Knowledge

Human knowledge spans across various domains such as medicine, law, and art. We aim to model this knowledge into more than a graph.

Method: Natural Language Processing (NLP)

Fully making use of the cutting-edge NLP techniques, we process a wide range of linguistic data that encode human knowledge.

Data: Multi-modal Text

Linguistic data can be found in various forms such as text, speech, and images. Also, the unit of analysis can be a word, sentence, or document. We handle them all.

Outcome: Real-world Applications

We apply our research to real-world problems and develop human-oriented applications that benefit society.

Projects

PI Message

Welcome to KaLC Lab

Shuntaro Yada, PhD

Thank you for e-visiting the Knowledge and Language Computing Laboratory (KaLC Lab) at the University of Tsukuba. I am Shuntaro Yada, the Principal Investigator (PI) of the KaLC Lab. I warmly welcome students interested in tackling real-world problems. This challenge always involves understanding human knowledge, and such professional knowledge is often encoded in language. Making use of the latest Natural Language Processing (NLP) techniques, we aim to model human knowledge and apply it to various domains, such as medicine, law, and art.

Students can freely explore their research topics while assisting with the lab's projects. See the How to Join page for prospective students. We also welcome collaborative research with other research groups and companies. Feel free to submit your inquiry via the contact form.
