Agile software development methods have become increasingly popular in the last years. Despite their popularity, they have been criticized for focusing on delivering functional requirements and neglecting the quality requirements. Several studies have reported this shortcoming. However, there is little known about the challenges organizations currently face when dealing with quality requirements....
[Background] Software inspections are extensively used for requirements verification. Our research uses the perspective of human cognitive failures (i.e., human errors) to improve the fault detection effectiveness of traditional fault-checklist based inspections. Our previous evaluations of a formal human error based inspection technique called Error Abstraction and Inspection (EAI) have shown encouraging...
[Background]: Developing conceptual models is an integral part of the requirements engineering (RE) process. Goal models are requirements engineering conceptual models that allow diagrammatic representation of stakeholder intentions and how they affect each other. A specific goal modeling language construct, the contribution of goal satisfaction of one goal to another, plays a central role in supporting...
The value of a software product diminishes due to emerging new requirements and gradual changes in system usage patterns over its lifespan, including other direct or indirect impacts from the surrounding environment. Often new requirements or changes cannot be addressed instantly; therefore, the system becomes less effective with incompatible or unused features, gradually degrading the overall value...
In this paper, we present an empirical study of 1,156 open source virtual reality (VR) projects from Unity List. Our study shows that the number of open source VR software projects are steadily growing, and some large projects attracting many developers are emerging. The most popular topic of VR software is still games. We also found that VR developers often face miss-commit of automatically generated...
[Background]: Conceptual modeling languages have been widely studied in requirements engineering as tools for capturing, representing and reasoning about domain problems. One of these languages, goal models, has been proposed for representing the structure of stakeholder intentions. Like most other conceptual modeling languages, goal models are visualized using box-and-line diagrammatic notations...
Sentiment Analysis (SA) in Software Engineering (SE) texts suffers from low accuracies primarily due to the lack of an effective dictionary. The use of a domain-specific dictionary can improve the accuracy of SA in a particular domain. Building a domain dictionary is not a trivial task. The performance of lexical SA also varies based on the method applied to develop the dictionary. This paper includes...
Background: research synthesis is still challenge in Software Engineering due to the heterogeneity of primary studies in the area. Also, it generates a significant volume of information which is complex to manage. Aims: to provide support to this kind of studies in SE. Method: we present the Evidence Factory, a tool designed to support the Structured Synthesis Method (SSM). SSM is a research synthesis...
