Takashi Kobayashi Lab
Machine-translated · View original
The lab analyzes software artifacts and development histories to support software development.

AboutAbout the lab
Putting reusable experience to work in development.
The Takashi Kobayashi Lab studies software engineering, particularly software maintenance and design support.
It takes an approach of analyzing large amounts of software artifacts to discover information that is useful for supporting development.
The analysis targets include not only source code and execution histories, but also the histories of development activities.
The lab builds support methods and tools by combining static and dynamic analysis techniques with natural language processing, data mining, and machine learning.
Key terms
- Software maintenance
- The ongoing work of modifying software after it has been completed, in order to fix defects and add features
- Static analysis and dynamic analysis
- Two ways of examining a program: by reading it without running it, and by actually running it
- Data mining
- A set of techniques for extracting useful rules and trends from large amounts of data

The lab conducts research on software engineering, particularly software maintenance and design support. It is interested in the approach of analyzing large amounts of software artifacts to inductively discover information that is useful for supporting development.
*Illustrative imageSoftware Maintenance and Design Support
Within software engineering, the lab focuses on maintenance, the work of continuing to fix software after it has been built, and on mechanisms that support design. It aims to apply reusable experience gained in one development effort to the next.
