The ongoing trend towards distributed development activities causes a growing need for specification activities and techniques. Each component leads to a large number of specification documents being exchanged, change managed and committed. The quality of the specifications influences the timing, costs and success of the development task. However, the quality of such specifications is often far from...
Requirements are the keystone of complex systems development. In order to reduce inconsistencies, requirements analysis is an important issue of systems engineering. In this context, there is a need for conciliating views of several stakeholders from different domains and for tracing these requirements from specification to realization. The computerization of analysis, with the help of a clearly defined...
Any reasonable implementation of privacy requirements can not be made through legal compliance alone. The belief that a software system can be developed without privacy being an integral concept, or that a privacy policy is sufficient as requirements or compliance check is at best dangerous for the users, customers and business involved. While requirements frameworks exist, the specialisation of these...
Unified Modeling Language (UML) is the most popular modeling language for analysis, design and development of the software system. There has been a lot of research interest in generating these UML models, especially class diagrams, automatically from Natural Language requirements. The interest in class diagrams can be attributed to the fact that classes represent the abstractions present in the system...
Ambiguity in natural language requirements has long been recognized as an inevitable challenge in requirements engineering (RE). Various initiatives have been taken by RE researchers to address the challenges of ambiguity. In this paper the results of a mapping study are presented that focus on the application of Natural Language Processing (NLP) techniques for addressing ambiguity in requirements...
The design of modern hardware systems is a very complex and time consuming process. At the beginning of the design process, requirements need to be specified. Errors in that early design stage derived by misinterpretation of the requirements can be hard to detect and require significant effort and costs to get fixed. To prevent errors, requirements should be written in a comprehensive and unambiguous...
Requirements are usually presented as Natural Language based documents. In the conceptual modeling phase, requirements are collected from different stakeholders and analyzed by requirement engineers. However, the size of the requirements documents can become very large, and the modeling process is quite time consuming and resource consuming. In order to solve this problem, much has been written on...
This paper describes the evolution of REQcollect (Requirements Collection). REQcollect was developed through several iterations of agile development and the transition of other projects. Multiple federal agencies have sponsored the work as well as transitioned the technologies into use. The parents of REQcollect are REQdb (Requirements Database) and DART3 (Department of Homeland Security Assistant...
Simulation technologies are imperative for embedded systems development. They enable the evaluation of decisions already early in development processes. Simulators are focused on a subset of effects that affect the operation of embedded systems. Accurate prediction of embedded system behavior on system level, however, requires the consideration of multiple effects, e.g. communication behavior, system...
Cyber security systems are comprised of a wide variety of interconnected systems. If these individual systems are not sufficiently designed and implemented to work well when integrated, additional opportunities for adversaries to hide and attack are created. To better enable researchers to broaden their scope and work together, they must be able to explore research in other areas and work across disciplines...
The advantage of textual use-cases is that they can be easily understood by stakeholders and domain experts. However, since use-cases typically rely on a natural language, they cannot be directly subject to a formal verification. In this paper, we present the FOAM method which features simple user-definable annotations, inserted into a use-case to make its semantics more suitable for verification...
Cloud computing is a promising IT paradigm which enables the Internet¢s evolution into a global market of collaborating services. Cloud computing semantic interoperability plays a key role in making this a reality. Towards this direction, a comprehensive and systematic survey of Cloud computing interoperability efforts by standardization groups, industry and research community is carried out. The...
In this article, the authors provide an example workflow-and a simple classification of user questions on the workflow's data products-to combine and interchange contextual metadata through a semantic data model and infrastructure. They also analyze their approach's potential to support enhanced semantic provenance applications.
Service oriented architecture (SOA) promotes highly standardized, loosely coupled and Web-enabled services to foster rapid, low-cost and easy composition of distribute applications. Critical to SOA software development is to acquire users' requirements and to provide service analysis and design techniques for identifying, conceptualizing, profiling, and rationalising service-enable applications. Semantic-enabled...
The goal of aspect-oriented requirements engineering (AORE) is to identify possible crosscutting concerns, and to develop composition specifications around those concerns. These compositions can be used to reason about potential conflicts in the requirements and to relate requirements to architecture in semantically meaningful ways. Recent work in AORE has moved from a syntactic approach to composition,...
