VISSOFT 2020 – Call for Papers

======================================

8th IEEE Working Conference on Software Visualization (VISSOFT 2020)

September 28-29, 2020, Adelaide, Australia

http://vissoft20.dcc.uchile.cl/

======================================

CALL FOR SUBMISSIONS

Software visualization is a broad research area whose general goal is
to enhance and promote the theory, realization, and evaluation of
approaches to visually encode and analyze software systems, including
software development practices, evolution, structure, and software
runtime behavior. Software visualization is inherently
interdisciplinary, drawing on theories and techniques from information
visualization and computer graphics and applying these in the software
engineering domain.

The VISSOFT conference is a venue for publishing and discussing
research related to software visualization. VISSOFT brings together a
community of researchers from software engineering, information
visualization, computer graphics, human-computer interaction, and data
science to discuss theoretical foundations, algorithms, techniques,
tools, and applications related to the visualization of software.

VISSOFT 2020, co-held with ICSME 2020, encourages a variety of
submissions that address outstanding challenges in software systems
using visualization. This includes technical papers, empirical
studies, applications, case studies, and papers that present novel
ideas and tools.

======================================

TOPICS OF INTEREST

– Innovative visualization and visual analytics techniques for
analysis of software engineering data. This includes source code,
dependencies, repositories, developer social networks such as
StackOverflow and GitHub, mobile app reviews, documentation,
runtime logs, and DevOps data.

– Visualization to support software development activities,
including design, requirements engineering, program comprehension,
software testing, and debugging.

– Interaction techniques and algorithms for software visualization.

– Visualization-based techniques in software engineering education.

– Integration of software visualization tools with development
environments.

– Empirical evaluation of software visualizations, including eye
tracking.

– Industrial experience with using software visualization.

– Applications of new technologies to enhance software
visualization, including virtual reality, augmented/mixed reality,
gamification, and artificial intelligence.

– Analytical approaches to understand software-related aspects based
on data science concepts.

We solicit papers that present original, unpublished research results.
Papers will be rigorously reviewed by an international program
committee. In addition to technical papers, VISSOFT features a New
Ideas or Emerging Results (NIER) track and a Tool Demonstrations (TD)
track. All accepted submissions will appear in the conference
proceedings and the IEEE Digital Library.

======================================

SUBMISSION TYPES

**Technical papers**:

A technical paper contribution must describe an in-depth and mature
research result relevant to software visualization. The content of a
technical paper can be at a maximum 10 pages long (including all
figures, tables, and appendices). However, the 10 page limit does not
include the bibliography, which is limited by two additional pages.

The submission of a video (up to 5 minutes in length) to accompany the
paper is highly encouraged to show interaction possibilities. Authors
who wish to submit a video can submit the video together with their
paper if the size of the video is smaller than 50 MB, otherwise a URL
to the video should be provided.

After the notification, authors can also submit an artifact (tool,
data, model, etc.)

Submission link: https://easychair.org/conferences/?conf=vissoft2020

**NIER/TD Track**:

The NIER/TD Track of VISSOFT accepts two types of contributions: New
Ideas and Emerging Results (NIER) and Tool Demonstrations (TD). Both
NIER and TD contributions have a page limit of 5 (including
bibliography).

NIER contributions describe work-in-progress and preliminary exciting
results. Authors are encouraged to include open questions and even
provocative hypotheses to get early feedback on their research ideas.
A sound evaluation is not required for NIER contributions. One of the
goals of the NIER Track is to foster collaboration among different
research groups.

Tool Demonstrations describe the design or actual utilization of
software visualization tools, with a focus on the architecture of the
tool or its use to gain new insights. During the conference, we will
organize an informal tool demonstration session where authors of TD
papers are requested to demonstrate their tools. The submission may
also contain a link to a screencast (e.g., YouTube or Vimeo) to show
the interaction possibilities offered by the tool.

VISSOFT 2019 – Summary

The IEEE Working Conference on Software Visualization (VISSOFT) is the main conference on Software Visualization. This year, the conference was held in Cleveland, OH, USA, co-located with ICSME between September 30th and October 1st, 2019. VISSOFT took place at the Hyatt Regency Cleveland at the Arcade. The program included two keynotes, one of them shared with SCAM’19, and the presentation of 8 full technical papers and 5 new ideas and emerging results / tool (NIER) demo papers (TD). As usual, the conference promoted lots of discussion and demos of visualizations. The shared keynote speech with SCAM was titled: “Visualization of Software-Clone Data: A Comprehensive Survey” and given by Rainer Koschke, who elaborated on the results of a survey of 68 papers of clone visualization techniques.

Software Evolution. The first session focused on software evolution and included the presentation of 2 full papers and 2 NIER/TD papers. In it, Juan Pablo Sandoval presented his work with Fabian Beck and Alexandre Bergel [1]. The paper elaborates on the use of the matrix visualization technique for the analysis of performance variations along various versions of a software system. Next, Carol V. Alexandru presented Evo-Clocks [2], a visualization that employs a node-link diagram for the analysis of the evolution of software metrics. In the diagram, nodes are depicted by circular pie chart visualizations. Then, a short paper [3] was presented, which introduces the Macaw visualization tool. The tool provides users a visualization of program evolution to support automated program repair tools that use genetic algorithms, which is integrated to kGenProg. Finally, the last presentation of the session was given by Alexandre Bergel. He presented a short paper [4] that introduces a lightweight visualization technique to examine source code variations and memory consumption.
Picture2

Meta-Analysis of Software Visualization. The second session was about meta-analyses of software visualization and included the presentation of 3 full papers. The first presentation was given by Fabio Petrillo, who presented a tertiary systematic literature review of software visualization [5]. The survey includes the analysis of 48 papers and confirmed a lack of rigorous evaluations and the need for empirical studies as well as found a lack of collaboration amongst software visualization researchers. Next, I presented a paper [6] that introduces an ontology, called VISON, that encapsulates the main concepts that characterize software visualization. The paper also links 70 software visualization tools that are publicly available. Finally, there was a presentation of a paper [7] that reports on a user study that involved 5 software engineers of a large company and 4 researchers to examine the usefulness of visualization for requirements monitoring.
Picture3

Eye Tracking, VR/AR. This year, I was invited to chair the last session of the first day that focused on the use of eye tracking and VR/AR in the context of software visualization. The session included the presentation of 1 full paper and 2 NIER/TD. The first presentation corresponded to a paper [8] that reports on the use of two linked views: one with a hierarchical edge bundling technique for context space and a graph visualization for embedded space, to visualize eye tracking data of source code exploration. Then, Sivasurya Santhanam from DLR presented a paper [9] that introduces an
architecture and an implementation of conversational interfaces for the Microsoft HoloLens device. In it, conversation interfaces are used for the exploration of visualizations of OSGi-based software architectures. Finally, the session ended with the presentation of a paper [10] that introduces CodeHouse, VR Code Visualization Tool.
Picture4

Demo and Posters. At the end of the day, we had a Demo and Poster Session, in which we enjoyed to test some awesome visualizations. An especial interest got the ones displayed in immersive virtual and augmented reality.
Picture5

Banquet. The traditional banquet was organized at The Butcher and The Brewer. The food and conversation was excellent. Many thanks to the organization!
Picture6

Keynote. On the second day, we had a keynote speech titled “Algorithms and Metaphors for Graph Visualization” by Stephen Kobourov. In it, he presented his work using map metaphors, which shown to be intuitive, for visualizing relational data sets. He demoed the GMap framework, and discussed applications and experimental results.
Picture7

Code Clones, Metrics, and Maintenance. Next, we had a session that included the presentation of 2 full papers and 1 NIERT/TD paper. The presenter of the first paper [11] introduced CloneCompass that uses combined views of a treemap matrix and an adjacency matrix to support the exploration of assembly code clones. Next, Craig Anslow presented a paper [12] to which I had the opportunity to contribute. In it, Craig introduced CorpusVis, a widget-based visualization to explore software metrics of systems in the Qualitas Corpus. The last presentation corresponded to a paper [13] that proposes using visualizations for exploring software maintenance activities.
Picture8

Paper Awards. In 2019, the paper “Performance Evolution Matrix: Visualizing Performance Variations along Software Versions” [1] by Juan Pablo Sandoval Alcocer, Fabian Beck and Alexandre Bergel received the Best Paper Award. Excellent work!
Picture9

Most Influential Paper Award. Finally, the conference concluded with the Most Influential Paper Award that went to
“A System for Graph-Based Visualization of the Evolution of Software” [14] by Collberg, C., Kobourov, S., Nagra, J., Pitts, J., & Wampler, K. The paper was presented by Christian Collberg.

Survey on Code Smell Detection and Use of Visualization Techniques

Dear Software Visualization and Code Smell Researchers,

We believe that you share with us the recognition on the important role that software visualization may play in software quality improvement initiatives. Software refactoring opportunities can be provided by detecting code smells. However, especially in large and complex legacy systems, many code smells can be detected and their influence can be local or spread across the whole system. That is where software visualization can be a great helper, for instance by providing a view of that spreadness, to help decision making on refactoring prioritization.

For over a year, we have been producing a systematic literature review (SLR), that has allowed us to draw some conclusions on the current state of the art in code smells detection and visualization techniques. We are now willing to share those conclusions with you. We would sincerely appreciate if you accept participating in a short online survey (it will take around 15m) to validate these conclusions. In recognition for your effort in fully completing this survey, we will provide you free first-hand access to our SLR. This is the anonymous link to the survey or https://iscteiul.co1.qualtrics.com/jfe/form/SV_a2Tc5wsRHaolcA5

Yours sincerely,
