Model Approach

A software pattern describes the core of the solution to a problem that tends to (re-)occur in a particular environment. Such patterns are commonly used as a means to facilitate the creation of an architectural design satisfying the desired quality goals. In this chapter, the practical challenges of efficient usage of patterns in domain-specific software development are presented. The specific domain considered here is the mobile domain, for which is given a sample collection of potentially useful patterns. After that, a novel generic architectural model approach for organizing patterns is presented. In this approach, the identification of relevant patterns is considered as the process of reducing the set of candidate patterns by domain-implied constraints. These constraints can be incorporated in a domain-specific generic architectural model that reflects the commonalities in the solutions of the particular domain. This approach has been validated with a real company application development case.

Important Challenge

An important challenge in software development is to have efficient tools for creating, debugging, and testing software components developed for specific business domains. This is more imperative if it is considered that a large number of users are not familiar with popular programming languages. Hence, Application Creation Environments (ACEs) based on specific Domain-Specific Languages (DSLs) can provide an efficient way for creating applications for a specific domain of interest. The provided ACEs should incorporate all the functionality needed by developers to build, debug, and test applications. In this chapter, the authors present their contribution in this domain based on the experience of the IPAC system. The IPAC system provides a middleware and an ACE for developing and using intelligent, context-aware services in mobile nodes. The chapter fully describes the ACE, which is a key part of the overall architecture. The ACE provides two editors (textual, visual), a wide functionality spectrum, as well as a debugger and an application emulator. The ACE is based on an Application Description Language (ADL) developed for IPAC. The ADL provides elements for the description of an application workflow for embedded systems. Through such functionality, developers are capable of efficiently creating and testing applications that will be deployed on mobile nodes.

To provide junior researchers with domain-specific concepts efficiently, an automatic approach for academic profiling is needed. First, to obtain personal records of a given scholar, typical supervised approaches often utilise structured data like infobox in Wikipedia as training dataset, but it may lead to a severe mis-labelling problem when they are utilised to train a model directly. To address this problem, a new relation embedding method is proposed for fine-grained entity typing, in which the initial vector of entities and a new penalty scheme are considered, based on the semantic distance of entities and relations. Also, to highlight critical concepts relevant to renowned scholars, scholars’ selective bibliographies which contain massive academic terms are analysed by a newly proposed extraction method based on logistic regression, AdaBoost algorithm and learning-to-rank techniques. It bridges the gap that conventional supervised methods only return binary classification results and fail to help researchers understand the relative importance of selected concepts. Categories of experiments on academic profiling and corresponding benchmark datasets demonstrate that proposed approaches outperform existing methods notably. The proposed techniques provide an automatic way for junior researchers to obtain organised knowledge in a specific domain, including scholars’ background information and domain-specific concepts.

Modeling Techniques

Core-periphery structure, the arrangement of a network into a dense core and sparse periphery, is a versatile descriptor of various social, biological, and technological networks. In practice, different core-periphery algorithms are often applied interchangeably despite the fact that they can yield inconsistent descriptions of core-periphery structure. For example, two of the most widely used algorithms, the k-cores decomposition and the classic two-block model of Borgatti and Everett, extract fundamentally different structures: The latter partitions a network into a binary hub-and-spoke layout, while the former divides it into a layered hierarchy. We introduce a core-periphery typology to clarify these differences, along with Bayesian stochastic block modeling techniques to classify networks in accordance with this typology. Empirically, we find a rich diversity of core-periphery structure among networks. Through a detailed case study, we demonstrate the importance of acknowledging this diversity and situating networks within the core-periphery typology when conducting domain-specific analyses.

This article describes how the enormous potential benefits provided by the cloud services, made enterprises to show huge interest in adopting cloud computing. As the service provider has control over the entire data of an organization stored onto the cloud, a malicious activity, whether internal or external can tamper with the data and computation. This causes enterprises to lack trust in adopting services due to privacy, security and trust issues. Despite of having such issues, the consumer has no root level access right to secure and check the integrity of procured resources. To establish a trust between the consumer and the provider, it is desirable to let the consumer to check the procured platform hosted at provider side for safety and security. This article proposes an architectural design of a trusted platform for the IaaS cloud computing by the means of which the consumer can check the integrity of a guest platform. TCG's TPM is deployed and used on the consumer side as the core component of the proposed architecture and it is distributed between the service provider and the consumer.

In view of unclear previous findings about the validity of self-assessed creativity, the hypothesis guiding the present study was that validity would be proven if self-assessed creativity was examined with respect to a specific domain, specific product, specific aspects of creativity, and in terms of specific criteria. The participants were 52 architecture students. The experimental task was to design a small museum in a described context. After completing the task, the students self-assessed their creativity in designing with seven open-ended questions, the Self-Assessment of Creative Design questionnaire, and a list of seven items tapping affective metacognitive aspects of the designing process. Thus, 21 creativity indicators were formed. Four expert architects, working independently, assessed the designs on nine creativity indicators: fluency, flexibility, elaboration, functionality, innovation, fulfilling specified design requirements, considering context, mastery of skills concerning the esthetics of the design representation, and overall creativity. The agreement among the architects’ evaluations was very high. The correlations between the nine corresponding indicators in students’ assessment of their design and those of the experts were positive and significant with respect to three indicators: fluency, flexibility, and overall creativity. On the contrary, the correlations of the rest noncorresponding indicators with those of the experts were not significant. The findings support the validity of self-assessed creativity with specific restrictions.

This paper introduces the process of developing web application of farm management information system (FMIS) for smallholder farmers in Malaysia by using rapid application development (RAD) prototyping methodology in information system research design. FMIS is important ICT solution to assist smallholder farmer to be more competitive in agriculture. The web application requirement determined through extraction process using physical data-driven design system from Malaysia Good Agriculture Practise (MyGAP) physical forms. Additionally, the functions and features of the system were determined through several questionnaires which were distributed to 209 smallholder farmers located in Taman Kekal Pengeluaran Makanan (TKPM) in Selangor. Selangor agricultural area together with smallholders farmers were chosen as respondents because Selangor is the highest internet penetration state in Malaysia. Subsequently, the design and analysis of FMIS are constructed by us including the database design, data flow design, system flow design and software development which was validated by two other experienced system analysts. The software development process were using PHP web development tool called Scriptcase version 8 which were taking less than 2 months to be completed. Furthermore, we also made a comparative study of an existing system available in the market to give additional competitive value to the new development of FMIS in Malaysia. The final developed FMIS is accessible through the official MyAgris website.

Model-Driven Engineering (MDE) is an approach to software development that uses models as primary artifacts, from which code, documentation and tests are derived. One way of assessing quality assurance in a given domain is to define domain metrics. We show that some of these metrics are supported by models. As text documents, models can be considered from a syntactic point of view i.e., thought of as graphs. We can readily apply graph-based metrics to them, such as the number of nodes, the number of edges or the fan-in/fan-out distributions. However, these metrics cannot leverage the semantic structuring enforced by each specific metamodel to give domain specific information. Contrary to graph-based metrics, more specific metrics do exist for given domains (such as LOC for programs), but they lack genericity. Our contribution is to propose one metric, called s, that is generic over metamodels and allows the easy specification of an open-ended wide range of model metrics.
