0 likes10,208 views
Refactorhub is a commit annotator designed for analyzing and collecting data on code refactoring, developed by researchers from Tokyo Tech. It facilitates refactoring data collection using tools like RefactoringMiner and offers a structured approach to annotating commit data related to code changes. The document outlines various aspects of the annotation process, including input and output structures for refactor operations.
