Bad smells are sub-optimal code structures that may represent problems needing attention.
We conduct an extensive literature review on bad smells relying on a large body of …

Predictive models are one of the most important techniques that are widely applied in many
areas of software engineering. There have been a large number of primary studies that …

Many companies develop software product lines-collections of similar products-by cloning
and adapting artifacts of existing product variants. Transforming such cloned product …

We investigate the relationship between faults and five of Fowler et al.'s least-studied smells
in code: Data Clumps, Switch Statements, Speculative Generality, Message Chains, and …

Duplicated code or code clones are a kind of code smell that have both positive and
negative impacts on the development and maintenance of software systems. Software clone …

Clones are generally considered bad programming practice in software engineering
folklore. They are identified as a bad smell (Fowler et al. 1999) and a major contributor to …

Context: Identifying defects in code early is important. A wide range of static code metrics
have been evaluated as potential defect indicators. Most of these metrics offer only high …

Modern code review is a critical and indispensable practice in a pull-request development
paradigm that prevails in Open Source Software (OSS) development. Finding a suitable …

Two similar code segments, or clones, form a clone pair within a software system. The
changes to the clones over time create a clone evolution history. In this work we study late …

As software becomes more and more complex due to increased number of module size,
procedure size, and branching complexity, software maintenance costs are often on the …
