Abstract

In this paper, we present an approach to improve source code retrieval using the structure of control statements. We develop a lexical parser that extracts structural information for each method including control statements and method identifiers. We present a source code retrieval model, named “derived structure retrieval model,” in which a retrieval conditions are defined as a sequence of control statements and/or method identifiers, and meaningful search conditions are derived from the given sequence. Experiments on the source code of Struts 2 Core show that the derived structure retrieval model outperforms the vector space retrieval model.
