Many existing clone detection approaches produce substantial amounts of clones that are irrelevant to software engineers. These false positives significantly hinder adoption of clone detection in practice and can lead to inaccurate research conclusions. ...

Tool support for code clones can improve software quality and maintainability. While significant research has been done in locating clones in existing source code, there has been less of a research focus on proactively tracking and supporting copy-paste-...

Scripting languages such as Python, Perl, Ruby and PHP are increasingly important in new software systems as web technology becomes a dominant force. These languages are often spoken of as having different properties, in particular with respect to ...

Graphics Processing Unit (GPU) have been around for a while. Although they are primarily used for high-end 3D graphics processing, their use is now acknowledged for general massive parallel computing. This paper presents an original technique based on [...

Despite ongoing research in the field of code duplication, clone research has not yet investigated when and how developers remove clones. We think knowing how developers select candidates for removal and what techniques they use to eliminate duplication ...

Cloning is widespread in today's systems where automated assistance is required to locate cloned code. Although the evolution of clones has been studied for many years, no attempt has been made so far to automatically distinguish the original source ...

When we encounter a defect in one part of a program, it is very important to find other parts of the program that may contain similar defects. In this paper, we propose a novel system to find similar defects in the large collection of source code. This ...

Cloned code is considered harmful for two reasons: (1) multiple, possibly unnecessary, duplicates of code increase maintenance costs and, (2) inconsistent changes to cloned code can create faults and, hence, lead to incorrect program behavior. Likewise, ...

Cloning imprint is the lasting effect of cloning on applications. This paper aims to analyze the clone imprint over time, in terms of the extension of cloning, the persistence of clones in methods, and the stability of cloned methods. Such level of ...

We often find clones in semantically related programs parts. This semantic relationship, not clones, is a prime reason for maintenance problems, as semantically related program parts must be changed in sync no matter of clones.

Only clones resulting ...

To answer the question, "Which kind of code clone has deleterious effects on maintainability?" this paper proposes a classification of code clones with a configuration (or Makefile) that determines which set of source files are compiled and linked.

In this position paper, we describe work-in-progress in detecting source code clones by means of analyzing and comparing the assembler that is produced when the source code is compiled.

Code clone detection has been so far tackled with several approaches (mainly textual, syntactic, and semantic), each performing best w.r.t. specific metrics and against consolidated but specific benchmarks. Hybrid approaches have been recently proposed ...

Code duplication is common in current programming-practice: programmers search for snippets of code, incorporate them into their projects and then modify them to their needs. In today's practice, no automated scheme is in place to inform both parties of ...

While clone detection and classification research for textual source code is well-established, clones in visual dataflow languages have only recently received attention. The accepted existing clone classification framework does not adequately capture ...

Although potential benefits are frequently mentioned in the literature, empirical evidence is missing to concretize the costs and benefits of clone management. Without precise estimation of the expected gain, clone management will hardly ever become a ...

The present paper discusses how clone sets can be generated from an very large amount of source code. The knowledge of clone sets can help to manage software asset. For example, we can figure out the state of the asset easier, or we can build more ...

Finding exact clones in source code can be efficiently handled using classical exact substring or subtree pattern matching techniques inspired from genomics applications. These methods may be wisely employed as a foundation to sketch new techniques ...
