The software Product Line (SPL) provides software customization by composing several different web services together. When further supported by Service-Oriented Architecture (SOA), SPL offers unprecedented advantages for reusing software artifacts in mass customization of software applications, leading to radically reduced time, cost, and effort of software development. A Petri-Net based visualization system for the software customization has been developed in our research group. This thesis works on enhancement of the prior work by introducing an interactive approach of software visualization for software customization. The proposed approach segregates the users based on their interaction with the system and the best suited visualizations are selected and displayed for the users. In this thesis an interactive framework based on Contextual Control Model has been proposed. A usability study has been conducted to validate the improvements in the usability of the proposed system compared to the existing system. Advisors/Committee Members: Yuan, Xiaobu

Context: The city metaphor is widely used in software visualization to represent complex systems as buildings and structures, providing an intuitive way for developers to understand software components. Various software visualization tools have utilized this approach. Objective: Identify the influence of the city metaphor on software visualization research, determine its state-of-the-art status, and identify derived tools and their main characteristics. Method: Conduct a systematic mapping study of 406 publications that reference the first paper on the use of the city metaphor in software visualization and/or the main paper of the CodeCity tool. Analyze the 168 publications from which valuable information could be extracted, and build a complete categoric analysis. Results: The field has grown considerably, with an increasing number of publications since 2001, and a changing research community with evolving interconnections between groups. Researchers have developed more tools that support the city metaphor, but less than 50% of the tools were referenced in their papers. Moreover, 85% of the tools did not use extended reality environments, indicating an opportunity for further exploration. Conclusion: The study demonstrates the active and continually growing presence of the city metaphor in research and its impact on software visualization and its derivatives.

Collaborative program comprehension via software visualization in extended reality

引用

INFORMATION AND software TECHNOLOGY 2022年 151卷

作者： Krause-Glau, Alexander Hansen, Malte Hasselbring, Wilhelm Univ Kiel Dept Comp Sci Christian Albrechts Pl 4 D-24211 Kiel Germany

Context: In software visualization research, various approaches strive to create immersive environments by employing extended reality devices. In that context, only few research has been conducted on the effect of collaborative, i.e., multi-user, extended reality environments. Objective: We present our journey toward a web-based approach to enable (location-independent) collaborative program comprehension using desktop, virtual reality, and mobile augmented reality devices. Method: We designed and implemented three mull-user modes in our web-based live trace visualization tool ExplorViz. Users can employ desktop, mobile, and virtual reality devices to collaboratively explore software visualizations. We conducted two preliminary user studies in which subjects evaluated our VR and AR modes after solving common program comprehension tasks. Results: The VR and AR environments can be suitable for collaborative work in the context of program comprehension. The analyzed feedback revealed problems regarding the usability, e.g., readability of visualized entities and performance issues. Nonetheless, our approach can be seen as a blueprint for other researchers to replicate or build upon these modes and results. Conclusions: ExplorViz's mull-user modes are our approach to enable heterogeneous collaborative software visualizations. The preliminary results indicate the need for more research regarding effectiveness, usability, and acceptance. Unlike related work, we approach the latter by introducing a mull-user augmented reality environment for software visualizations based on off-the-shelf mobile devices.

Java Code Hierarchical visualization Tool (JCHVT) is a software visualization system oriented to Java source code, which has been designed on the concept of service and with reference to Class diagram and Polymetric view. JCHVT is able to automatically create a hierarchical view of the software system, which can reflect the relationships among classes, structure of the system and even the roles of classes played in the system. Meanwhile, JCHVT provides various methods of human-computer interactions which can help user to understand the graph and identify the useful information in the view.

Starting with a selective retrospective of the history of software visualization, I will identify various trends and paradigms of previous and current research. In particular, I will discuss examples of applying visualization techniques to analyze the past and present state of software as well as to predict its future development. I will argue that prediction is an important task, but that software visualization research has only scratched the surface of it. As a consequence, speculative visualization will be one of the major future challenges identified in this talk.

software Cartography: thematic software visualization with consistent layout

JOURNAL OF software MAINTENANCE AND EVOLUTION-RESEARCH AND PRACTICE 2010年第3期22卷 191-210页

software visualizations can provide a concise overview of a complex software system. Unfortunately, as software has no physical shape, there is no 'natural' mapping of software to a two-dimensional space. As a consequence most visualizations tend to use a layout in which position and distance have no meaning, and consequently layout typically diverges from one visualization to another. We propose an approach to consistent layout for software visualization, called software Cartography, in which the position of a software artifact reflects its vocabulary, and distance corresponds to similarity of vocabulary. We use Latent Semantic Indexing (LSI) to map software artifacts to a vector space, and then use Multidimensional Scaling (MDS) to map this vector space down to two dimensions. The resulting consistent layout allows us to develop a variety of thematic software maps that express very different aspects of software while making it easy to compare them. The approach is especially suitable for comparing views of evolving software, as the vocabulary of software artifacts tends to be stable over time. We present a prototype implementation of software Cartography, and illustrate its use with practical examples from numerous open-source case studies. Copyright (C) 2010 John Wiley & Sons, Ltd.

The paper presents a new 3D representation for visualizing large software systems. The origins of this representation can be directly traced to the SeeSoft metaphor. This work extends these visualization mechanisms by utilizing the third dimension, texture, abstraction mechanism, and by supporting new manipulation techniques and user interfaces. By utilizing a 3D representation we can better represent higher dimensional data than previous 2D views. An overview of our prototype tool and its basic functionality is given. Applications of this method to particular software engineering tasks are also discussed.

In the field of software visualization controlled experiments are an important instrument to investigate the specific reasons, why some software visualizations excel the expectations on providing insights and ease task solving while others fail doing so. Despite this, controlled experiments in software visualization are rare. A reason for this is the fact that performing such evaluations in general, and particularly performing them in a way that minimizes the threats to validity, is hard to accomplish. In this paper, we present a structured approach on how to conduct a series of controlled experiments in order to give empirical evidence for advantages and disadvantages of software visualizations in general and of 2D vs. 3D software visualizations in particular.

INFORMATION AND software TECHNOLOGY 2013年第11期55卷 1860-1883页

作者： Novais, Renato Lima Torres, Andre Mendes, Thiago Souto Mendonca, Manoel Zazworka, Nico Univ Fed Bahia Dept Comp Sci BR-41170290 Salvador BA Brazil Univ Fed Bahia Dept Informat Technol BR-41170290 Salvador BA Brazil

Background: software evolution is an important topic in software engineering. It generally deals with large amounts of data, as one must look at whole project histories as opposed to their current snapshot. software visualization is the field of software engineering that aims to help people to understand software through the use of visual resources. It can be effectively used to analyze and understand the large amount of data produced during software evolution. Objective: This study investigates software Evolution visualization (SEV) approaches, collecting evidence about how SEV research is structured, synthesizing current evidence on the goals of the proposed approaches and identifying key challenges for its use in practice. Methods: A mapping study was conducted to analyze how the SEV area is structured. Selected primary studies were classified and analyzed with respect to nine research questions. Results: SEV has been used for many different purposes, especially for change comprehension, change prediction and contribution analysis. The analysis identified gaps in the studies with respect to their goals, strategies and approaches. It also pointed out to a widespread lack of empirical studies in the area. Conclusion: Researchers have proposed many SEV approaches during the past years, but some have failed to clearly state their goals, tie them back to concrete problems, or formally validate their usefulness. The identified gaps indicate that there still are many opportunities to be explored in the area. (C) 2013 Elsevier B.V. All rights reserved.
