Respecify is a new web-based requirements authoring tool using constrained natural language (CNL) to guide the authoring process and drive the creation of alternative views that elucidate the complexity of specifications, thus reducing the occurrence of certain types of requirements quality defects. This tool demo motivates Respecify's existence, its key features, and evaluates its current use in...
Let G be a graph with minimum degree at least 2. A vertex subset S is a 2-tuple total dominating set of G if every vertex is adjacent to at least two vertices in S. The 2-tuple total domination number of G is the minimum size of a 2-tuple total dominating set. In this paper, we are concerned with the 2-tuple total domination number of a Harary graph H2m+1, 2n+1 with 2n+1 = (2m+1)l. For m = 1 and m...
Eliminating or reducing skill gaps in the job market is critical to putting people back to work, reducing the unemployment rate, and increasing the labor market participation rate. A key element in closing the skills gap is accurately identifying the mismatch between the skills expected by employers and those possessed by job seekers. In this study, our goal was to profile job titles by effectively...
Results of development and practical introduction of advanced professional English training course into a higher school educational process for masters of sciences in electro-mechanics at polytechnic university's electrical engineering department are introduced.
Relatively little research has addressed the role of LI in the perception of English speech contrasts by Chinese learners of English as L3. The present study investigates the role of LI in the perception of the English alveolar-velar nasal coda contrast (/n/ vs. /η/) after the vowels /i Λ æ/ by bilingual Changsha Chinese speakers, whose LI is Changsha Chinese and L2 is Standard Mandarin. Changsha...
The publication of Guidance for College English Teaching is the symbol for a new round of college English teaching reformation in China. And one of the new directions it set for the reformation is to set up English for Specific Purposes (ESP) courses, as a response to the new requirements for talents by the development of China's society and economy. No reformation of teaching can be successful without...
Today’s businesses increasingly rely on cloud computing, which brings both great opportunities and challenges. One of the critical challenges is resiliency: disruptions due to failures (either accidental or because of disasters or attacks) may entail significant revenue losses (e.g., US$ 25.5 billion in 2010 for North America). Such failures may originate at any of the major components in a cloud...
Companies lost a lot of money owing to data quality problems. This because bad decisions based on incorrect information, breach of rules or the failure to deal with customer problems in a timely manner. Currently data have become one of the most important assets for the organizations. Thus, data quality is a concern that involves both information technology people and business people. In the context...
This paper discusses an integrated methodology to structure and formalize business requirements in large dataintensive projects, e.g. data warehouses implementations, turning them into precise and unambiguous data definitions suitable to facilitate harmonization and assignment of data governance responsibilities. We place a business information model in the center — used end-to-end from analysis,...
Process utilised in service organisations are justly regarded as crucial resources. Each process utilised in rendering a service appreciably play a role in the cost of managing the organisation. Processes impacts on the service levels customers expects and experience from the service provider. Higher Education providers are not immune from poor performing and costly processes. The researched institution...
In component based software engineering, quality of service (QoS) of component is getting more attention. So, how to define and describe QoS of components is a problem to be solved. In the paper, a model driven QoS modeling method is proposed called two level domain modeling based on MDA, declaring a generic QoS meta-model. The QoS meta-model can be applied in different business domains to generate...
A body of knowledge is a term used to represent the complete set of concepts, terms and activities that make up a professional domain. It encompasses the core teachings, skills and research in a field or industry. So far, the discipline of RE is lacking an official Requirements Engineering Body of Knowledge (REBoK). This working session brings together researchers and practitioners to elaborate the...
Despite the success of orchestration and choreography for Web services composition, there are still challenges to be overcome such as the difficulty for management of complex control-flow executions, the communication cost associated with service interactions, knowledge of the business process by services and even their compatibility in compositions. As an alternative to traditional approaches, in...
The emergence of Systems of Systems Engineering (SoSE) poses challenges to the consistent use of terminology within and/or across heterogeneous sectors such as transport, energy and defence. In preparation for Horizon 2020, an €80 billion financial instrument running from 2014 to 2020 to implement the Europe 2020 strategy, the European Commission funded T-AREA-SoS project to formulate a strategic...
The knowledge-intensive nature of business innovation paradigms requires advanced method for managing the informative resources in the scope of an enterprise, especially in a virtual enterprise. In this context, a challenging task is to support the participation of workers to elicit/codify their tacit domain knowledge, providing the means to convert it into a more explicit and processable one. To...
The telecommunications sector has experienced significant changes over the past few years. The advent and rise of new applications and services, together with a competitive market, has led to a complex scenario in which quality of service (QoS) plays a major role. Under this condition, novel QoS regulation and standardization initiatives are required. During the last few years new terms and concepts,...
Service Networks (SNs) are open systems accommodating the co-production of new knowledge and services through organic peer-to-peer interactions. Key to broad success of SNs in practice is their ability to foster and ensure a high performance. By performance we mean the joint effort of tremendous interdisciplinary collaboration, cooperation and coordination among the network participants. However,...
Requirements Engineering (RE) is about achieving a shared understanding about the software system to be built. No withstanding the importance of other RE activities, requirements specification deserves special attention due to its documentation purposes: to communicate requirements, someone has to write them down. In this paper we present RSLingo, a linguistic approach for improving the quality of...
Today, enterprises to be efficient and competitive within their business environments should seamlessly adapt, collaborate and interoperate with each other. However, the diversity in the way they organize their knowledge through ontologies, brings about the crucial need for establishing semantic interoperability between all communicating parties. One approach to solve this problem is the use of MENTOR,...
Closeness in meaning of the terms in the information systems and software engineering may result in discussion of using proper affiliated terms while covering the scope of research. An example is touched in this exploratory study, which discusses flexibility and its affiliated terms: changeability, adaptability, compatibility, flexibility, expandability, extendibility, extensibility and portability...
