Requirements engineering (RE) for self-adaptive systems (SAS) is an emerging research area. The key features of such systems are to be aware of the changes in both their operating and external environments, while simultaneously remaining aware of their users' goals and preferences. This is accomplished by evaluating such changes and adapting to a suitable alternative that can satisfy those changes...
In cognitive gameplay, players must identify inputs, classify and integrate them in a contextually appropriate manner, then draw conclusions and provide feedback to the game engine to demonstrate their mastery of the challenge. Established requirements practices do not exist for this domain and game development teams rely upon ad hoc approaches to specification and iterative requirements-through-implementation-and-test...
Rationale and rationale management have been playing an increasingly prominent role in software system development mainly due to the knowledge demand during system evaluation, maintenance, and evolution, especially for large and complex systems. The rationale management for requirements engineering, as a commencing and critical phase in software development life cycle, is still under-exploited. In...
While goals models can visually present alternate ways for achieving goals and how actors depend on each other, it can be challenging to follow the reasoning through complex paths in the model. In earlier studies which tested the utility of procedures for guiding analysts to perform interactive forward and backward reasoning through i* models, we uncovered several difficulties faced by study participants...
The impact of non-functional requirements (NFRs) over software systems has been widely documented. Consequently, cost-effective software production method shall provide means to integrate this type of requirements into the development process. In this vision paper we analyze this assumption over a particular type of software production paradigm: model-driven development (MDD). We report first the...
This paper reports on work that is investigating the application of ontology engineering and natural language processing to software engineering. Our focus is the transition from requirements to design which remains one of the main challenges in software engineering. A key reason for why this is so challenging is that the vast majority of requirements documents are informal, written in natural language,...
Today, software systems are moving towards online deployment as collaborative composite services, the operating environments and users' needs for which are continuously changing. Thus, it is important to understand how to cope with run-time requirements by dynamic adaption at different levels. This paper aims to summarize our general position and understanding of this problem. In particular, we introduce...
The paper describes the quotations gathered during interviews and focus groups during a consulting engagement to help the client improve its requirements engineering (RE) process. The paper describes also a model of the software lifecycle derived from a Michael Jackson quotation, a model that explains about 95% of the quotations that we gathered. In particular, it explains why basic requirements determination...
This paper describes the application of a UML profile in the requirements modeling of a multi-agent system project. The profile at issue was designed with the purpose of modeling reactive and cognitive agents, as well as actions, perceptions, goals and plans for those agents in a collecting and analysing requirements level. In this paper we will describe the developed profile as well as its application...
Requirements are commonly vague and ambiguous. In this paper, we describe an automated Inconsistency Checker called MaramaAI for checking for high-level inconsistency between textual requirements, abstract interactions and Essential Use Cases. We use concepts of phrase extraction and essential interaction patterns to carry out these checks. We provide further support for checking of requirements quality...
The identification of abstractions, i.e. terms that have a particular significance in a given domain, and such that they can indirectly characterize the most salient features of the document in which they appear, has often been recognized as a useful tool in the analysis of domain descriptions and requirements documents in software development. In this paper we propose a new technique for the identification...
Peer reviews have been identified as one of the best practices in requirements engineering. The most formal peer review technique - inspection - has been found to be effective for the discovery of defects in documents. Nonetheless, many software companies practice inspections infrequently or not at all. For instance, some engineers consider inspections to be uncreative work that adds costs. This paper...
We posit that swarm intelligence can be applied to effectively address requirements engineering problems. Specifically, this paper demonstrates the applicability of swarm intelligence to the requirements tracing problem using a simple ant colony algorithm. The technique has been validated using two real-world datasets from two problem domains. The technique can generate requirements traceability matrices...
Non-functional requirements are emerging as one of the most crucial factors for successful information system development in service-oriented organizations. Non-functional requirements involve not only software characteristics but also numerous organizational elements. This study proposes a conflict analysis method for non-functional requirements of information systems. This method includes ontologies,...
We investigate distributed requirements development through a series of in-depth interviews, and document the practices as process-patterns showing stakeholder roles, locations, interactions, and tool support.
Requirements engineering is the foundation of software engineering, and quality of requirements engineering determines the quality of projects, while the traditional approaches do not meet the changing needs of the environment, it is difficult to describe by the unified and standardized form, but the ontology is a formal description of the concept of sharing, stressing the link between real entities,...
Requirements verification for complex software system has become more and more important in requirements engineering and it is one of the most helpful strategies for improving the quality of software system. Related work shows that requirement elicitation and analysis can be facilitated by semantic technologies and domain ontology. A new methodology for verifying software requirements with structural...
Design rationale in software engineering fills in the gaps between the original requirements of a system and the finished product encompassing decisions, constraints and other information that influenced the outcome. Existing research corroborates the importance of design rationale to capture knowledge assets, particularly in the context of the global enterprise, with its increased risk of knowledge...
Large-scale and complex system exhibits adaptive feature, and evolutionary emergence of collective behaviors is its fundamental phenomena. Considering service oriented requirements engineering (SORE), this paper explores requirements semantics acquisition technique and analyzes its adaptive feature. The strategy of evolutionary growth to gain domain specific requirements semantics model is proposed...
