Many clone detection tools have been proposed in the literature. However, our knowledge of
their performance in real software systems is limited, particularly their recall. In this paper …

Most previous work on code-clone detection has focused on finding identical clones, or
clones that are identical up to identifiers and literal values. However, it is often important to …

Code duplication or copying a code fragment and then reuse by pasting with or without any
modifications is a well known code smell in software maintenance. Several studies show …

In previous work, we introduced the concept of structural clone as recurring configurations of
simple clones (ie, similar code fragments). We also described a technique for detection of …

Cloned code often complicates code maintenance and evolution and must therefore be
effectively detected. One of the biggest challenges for clone detectors is to reduce the …

Over the last decade many techniques and tools for software clone detection have been
proposed. In this paper, we provide a qualitative comparison and evaluation of the current …

Although numerous different clone detection approaches have been proposed to date, not a
single one is both incremental and scalable to very large code bases. They thus cannot …

Despite the conventional wisdom concerning the risks related to the use of source code
cloning as a software development strategy, several studies appeared in literature indicated …

Clone detector results can be better understood with tools that support visualization and
facilitate in-depth analysis. In this tool demo paper we present VisCad, a comprehensive …

Unnecessary repeated codes (clones) have not been well documented and are difficult to
maintain. Code clones may become an important problem in software development cycle …
