Caesar : a social code review tool for programming education

[摘要] Caesar is a distributed, social code review tool designed for the specific constraints and goals of a programming course. Caesar is capable of scaling to a large and diverse reviewer population, provides automated tools for increasing reviewer efficiency, and implements a social web interface for reviewing that encourages discussion and participation. Our system is implemented in three loosely-coupled components: a language-specific code preprocessor that partitions code into small pieces, filters out uninteresting ones, runs static analysis, and detects clusters of similar code; an incremental task router that dynamically assigns reviewers to tasks; and a language-agnostic web interface for reviewing code. Our evaluation using actual student code and a user study indicate that Caesar provides a significant improvement over existing code review workflows and interfaces. We also believe that this work contributes a modular framework for code reviewing systems that can be easily extended and improved.
