Software clones are considered harmful in software maintenance and evolution. However, despite a decade of active research, there is a marked lack of work in the detection and analysis of near-miss software clones, those where minor to extensive modifications have been made to the copied fragments. In this thesis, we advance the state-of-the-art in clone detection and analysis in several ways. First, we develop a hybrid clone detection method. Second, we address the decade of vagueness in clone definition by proposing a metamodel of clone types. Third, we conduct a scenario-based comparison and evaluation of all of the currently available clone detection techniques and tools. Fourth, in order to evaluate and compare the available tools in a realistic setting, we develop a mutation-based framework that automatically and efficiently measures (and compares) the recall and precision of clone detection tools. Fifth, we conduct a large scale empirical study of cloning in open source systems.

Source code examples are valuable to developers needing to use an unfamiliar application programming interface (API). Numerous approaches exist to help developers locate source code examples; while some of these help the developer to select the most promising examples, none help the developer to reuse the example itself. Without explicit tool support for the complete end-to-end task, the developer can waste time and energy on examples that ultimately fail to be appropriate; as a result, the overhead required to reuse an example can restrict a developer's willingness to investigate multiple examples to find the “best” one for their situation. This paper outlines four case studies involving the end-to-end use of source code examples: we investigate the overhead and pitfalls involved in combining a few state-of-the-art techniques to support the end-to-end use of source code examples.
