RESEARCH TOPICS

Agents

01
  • Artifitial intelligence
  • Knowledge processing
  • Multi-agent cooperation
  • Planning

Agents are programs and models that autonomously gather information on the network on behalf of users and make decisions in a resourceful manner. They can process large amounts of data and respond to unpredictable situations.
Achieving flexibility like human intelligence is the ultimate goal of our research.

Knowledge Web

02
  • Semantic Web
  • Linked Open Data (LOD)
  • Ontology

This research is conducted to analyze the vast amount of data scattered across the Web, extract useful meaning, and connect it to new value.
We are developing technologies to loosely link and cross-analyze disparate data.

Intelligent software engineering

03
  • Self-adaptation
  • Goal-oriented requirements engineering
  • Review mining

The goal of this research is to reduce the cost of developing and operating increasingly large software systems while meeting the ever-changing needs of the marketplace. We aim to develop useful software that makes full use of advanced theory, such as self-adaptive systems that autonomously change their behavior in response to changing conditions to achieve their own ultimate goals.

Data mining

04
  • Machine learinng
  • Text mining
  • Privacy-presreving data mining

We are exploring technologies that collect various types of open data to understand real-world situations in real time. While aiming to provide detailed analysis and appropriate services as needed, we are also developing technologies to analyze large amounts of data while protecting privacy and preventing the unexpected leakage of personal information due to the accumulation and linking of information originating from individuals.
