The task abstraction and aggregation in a business process can help to (1) obtain customized descriptions of a business process for different users, and (2) derive user interfaces of a business process related to the participating users. This paper proposes an approach for task abstraction and aggregation of a business process based on a role-enriched business process model. For each user role, tasks...
User profiling is a typical big data service created and utilized by an increasing number of Internet venders, which maintains a customized model of interests or essential attributes of their existing users by looking for insights into their behaviors. The Internet industry's best practices indicate that user profiles can help venders much more sufficiently understand their customers. As a result,...
Although working in teams is an effective method for students to learn skills necessary for information systems, the optimal combination of team members to maximize the learning effectiveness has yet to be clarified. This study investigates the relationship between the combination of students' personality characteristics and learning effectiveness in three information system lecture courses. Two Five...
In this paper we propose a new internationalization model for databases. This model is intended to enable the internationalization (i18n) in a database, thus facilitating the work of both the database developer as well as the translator which performs its localization (l10n). The use of this model should reduce the developer's effort and allow the translator not to worry about application implementation...
The increasing rate of the smart technology implementations in the energy sector brings new control solutions for distributed renewable energy sources (DRES) to tackle the additional challenges on the distribution network that arise from increased integration of renewable energy sources (RES). With these new control solutions, a possibility of new services that could be offered on electricity and...
Nowadays, gamification elements have been applied beyond of traditional games that we know, an example is their application in academic area in software engineering, where them have been supported the students' learning and the accomplishment of activities in projects. In this context, gamification elements have been applied in very few investigation studies to improve the integration of team work...
The speed of development of the IT industry as well as the computational power which are increasing exponentially, create great competitiveness in the process of development but also in the launching of software products on the market. Automated testing comes to help with these challenges by trying to increase the speed of development by offering fast feedback and trustworthy quality by means of repeated...
Internet of Things, IoT, connects physical objects and the cyberspace, which provides potentials to leverage city-scale merits of IT services. It covers complicated integration of hardware, software, deployment and operation in both of time and spatial dimensions. It presents a broad challenge in design and operation processes. An IoT-empowered city platform is required to accommodate a wide spectrum...
Residential broadband consumption is growing rapidly, increasing the gap between Internet service provider (ISP) costs and revenues. Meanwhile, proliferation of Internet-enabled devices is congesting access networks, degrading end-user experience, and affecting content provider monetization. In this paper, we propose a new model whereby the content provider explicitly signals fast- and slow-lane requirements...
Software Product Line (SPL) consists in an approach that enables software reuse by allowing the creation of software applications through the features composition to address a particular domain. Framework Product Line (FPL) is an extension of SPL, whose features composition result in targeted frameworks, which are used to address subdomains of applications. Model-Driven Engineering is a promising...
The Internet can be considered as the most important infrastructure for modern society and businesses. A loss of Internet connectivity has strong negative financial impacts for businesses and economies. Therefore, assessing Internet connectivity, in particular beyond their own premises and area of direct control, is of growing importance in the face of potential failures, accidents, and malicious...
The most recent trends in the electronic commerce research have suggested that forming an ecosystem around a platform would create a winning solution. The ecosystem, consisting of vendors and external actors, would create competitive advantage for the platform owner. Furthermore, the sheer number of the actors has been used as the measure of the ecosystem's well-being against competing ecosystems...
Research has shown that gender diversity correlates positively with innovation and productivity in many professional engineering and technology domains. Yet, software development teams are dominated by males. In this paper, we aim at understanding whether female software professionals, compared to male, have different perceptions on a) team performance and dynamics, b) their own personal performance,...
GitHub is the largest collaborative source code hosting site built on top of the Git version control system. The availability of a comprehensive API has made GitHub a target for many software engineering and online collaboration research efforts. In our work, we have discovered that a) obtaining data from GitHub is not trivial, b) the data may not be suitable for all types of research, and c) improper...
Presents the research results in efficiency assessment of contactless technologies of fare payment implementation on public transport. The project effectiveness assessment methodology has been developed on the synthesis method basis of expert assessments and prof. A. Egorshin's methods. The methodology allows to evaluate several effect types from the project implementation and to perform calculations...
Software startups can be subject to extreme money and time constraints while hoping for delivering reliable software. In a harsh startup environment, software may face quality downgrade either by improper process management or incapable human resources. Among the many, security is a fragile software quality characteristic responsible for severe negative consequences such as jeopardizing a startup's...
Nowadays, in the period of the digitalization and knowledge economy development, majority of activities result in the increase of data that should be captured. In each area of business, there is an increasing urge to extract the knowledge from data in a timely manner in order to be able to make shifts that ensure a competitive advantage. Thus, the knowledge of methods and techniques of big data processing...
The recent upsurge of Apps, APIs and Cloud platforms, combined with the perpetual need of shorter time to market, motivates the need for approaches for rapid software engineering to compose applications quickly. In this paper, we propose a portal based approach to intelligently assist in creating composite applications. We discuss the underlying concepts and the techniques proposed in our approach,...
Context - Software engineering practices are chal-lenging activities in the startups' context due their limited resources and need to create high-tech and innovative products. The challenge becomes even bigger when taking into consideration the startups' search for highly scalable business models. Problem - Since they cannot rely on such a heavyweight software processes they need to resort to alternative...
As security incidents continue to impact organisations, there is a growing demand for systems to be ‘forensic-ready’ - to maximise the potential use of evidence whilst minimising the costs of an investigation. Researchers have supported organisational forensic readiness efforts by proposing the use of policies and processes, aligning systems with forensics objectives and training employees. However,...
