Welcome to IWoR 2018!

We are pleased to announce IWoR 2018, the 2nd edition of the international workshop dedicated to software refactoring.

The goal of the 2nd International Workshop on Refactoring (IWoR 2018) is to provide an informal interactive forum for researchers and practitioners to exchange ideas and experiences, streamline and foster research on software refactoring, identify some common ground of their work, share lessons and challenges, thereby articulating a vision for the future of software refactoring.

Workshop Overview

Successful software products evolve through a process of continuous changes as bugs are fixed, new features added, and quality issues addressed. Refactoring supports the volatile software lifecycle by providing better ways to reduce and manage the growing complexity of software systems while improving developer productivity. Refactoring can be performed at all levels from requirement specification down to source code level, and, in essence, involves improving the internal structure of a software artefact without altering its functionality. In spite of the popularity of refactoring both in practice and as a research topic, many open questions remain, particularly in terms of understanding how refactoring is performed, measuring the impact of refactoring, and improving tool support in all areas of refactoring.

Workshop Themes

We invite submissions from both academia and industry on any topic that is refactoring related, including, but not limited to:

• Source code refactoring
• Requirement, design and architectural refactoring
• Refactoring of mobile, web and cloud applications
• Refactoring opportunities detection and recommendation
• Tool support for refactoring
• Mining refactoring changes from software repositories
• Evaluation and benchmarking of refactoring methods
• Refactoring in Model Driven Engineering
• Code smell detection and correction
• Search based refactoring
• Effect of refactoring on system complexity and quality
• Empirical studies and experience reports
• Software remodularization
• Model transformation
• Introduction of design patterns through refactoring
• Machine learning applied to software refactoring
• Role of refactoring in evolution and migration
• Refactoring in the software lifecycle
• Refactoring and testing

Important Dates

• June 17 June 22: Deadline for submissions ( Extended deadline!)
• July 15: Notification of authors
• July 31: Camera-ready
• Sept 04: Workshop date.

Submission

We solicit four types of submission:

• Full research papers (max 8 pages)
• Position papers (max 4 pages)
• Tool demo papers (max 4 pages)
• Industrial presentation (max 2 pages)

These different categories offer researchers who are at different stages in their research maturity the opportunity to benefit from workshop participation. Page limits include references.

All paper submissions will be reviewed by three program committee members. The authors of accepted submissions will be asked to join the workshop. We will encourage all participants to submit a paper of any of the four categories, but the workshop will be open. All interested parties are welcome to register, even without an accepted paper.

Papers must be submitted electronically through the ASE 2018 submission site. All submissions must come in PDF format and conform, at time of submission, to the ACM Proceedings Template (LaTEX users must use\documentclass[sigconf,review,anonymous]{acmart}).

Proceedings and Special Issue

Accepted papers will be published in the workshop proceedings in the IEEE digital library.

A selection of the best papers will be invited to submit extended versions for tentative publication in a Special Issue of a journal (to be confirmed).
