| Outline of Final Research Achievements |
Understanding unfamiliar source code is inherently difficult for a software engineer, despite its importance. It is, however, still hard for a system to help in this activity, for lack of ways of both representing semantic chunks and of preparing a rich dictionary of chunks.
This research proposed an integrated framework for annotating and searching source code. In the framework, each engineer gathers (annotates) semantic chunks that have the same meaning and interactively generalizes them to get a search pattern. As a result, a dictionary of semantic chunks together with their search patterns is incrementally created through engineer collaboration. Two representations are used: a tuple of nodes of an abstract syntax tree (AST) for a semantic chunk and a classifier on generative attribute vectors for search patterns.
