Dynamic service composition framework for service‐oriented architectures based e‐government in Cameroon

Abstract

E-government has become a strategic tool for managing public administration. It makes it possible to improve interoperability between government's computer systems agencies. Taking profit to technological advances, notably the internet and web services, it has been associated with service-oriented architectures (SOA). Serviceoriented e-government has thus grown rapidly in developed countries. He has also gradually established itself in many projects in developing countries to take advantage to the economic benefits derived from SOA. However, when the activity of stakeholders becomes important in an e-government based on SOA, the scalability becomes a major challenge. This is even more striking in developing countries, which suffer from less robust infrastructures and poor energy supply. The scalability has its origins mainly in dynamic service composition operations. This is why this work proposes to improve the dynamic service composition layer to deal with the scalability in case of service-oriented e-government in developing countries. This makes it possible to construct and dynamically enrich each system with a service composition server, a registry and a library of requests associated with their composite services. Thus, each system checks its ability to process a request locally before sending it to a higherlevel system. The paper demonstrates that using this participatory approach, the latency of the majority of end-user requests is significantly shortened. Beyond this important aspect, our approach can provide with a good solution for Cameroon suffer from infrastructural insufficiency and energy instability. The evaluation of this architecture gave us satisfactory results.

The Adjusting Influence of Social Media’s User-Generated-Knowledge (SMUGK) in Grasping the Contribution of Cognitive and Technological Factors in Citizens' Perceptions of Satisfaction from E-Government Services in the Global South Context: The Case of Oman

“…VD is still important, even if it does not directly impact user satisfaction. VD can help ensure that egovernment services are meeting citizens' needs and being developed sustainably (Célestin Parfait et al, 2022;Maznorbalia & Awalluddin, 2021).…”

“…Moreover, knowledge created by users of egovernment can encourage the creation, sharing, and reuse of knowledge, as well as recognise and reward knowledge contributions and achievements, which can foster a culture of learning and innovation within the public sector (Wu et al, 2020). This issue will establish a digital infrastructure and environment that enables various actors inside and outside the government to access, exchange, and collaborate on knowledge to enhance the offered e. services (Célestin Parfait et al, 2022).…”

“…This approach involves actively engaging with the public to generate, disseminate, and utilise knowledge and seeking their opinions and contributions (Allmann & Radu, 2023). The e ciency and outcomes of knowledge management procedures can be enhanced by leveraging cuttingedge technologies like social media, mobile devices, cloud computing, and arti cial intelligence (Célestin Parfait et al, 2022;Charbaji et al, 2020).…”
