Medical information systems are in perpetual evolution which makes them different from each other in each hospital. These different systems compose a heterogeneous, distributed system with high complexity. Thus interoperability of medical information systems is one of the main challenges of the IT society. Semantic interoperability in healthcare is especially important when all the varying types of data need to interact.A lot of works tried to solve even partially this problem of interoperability. This paper highlights the most relevant of them and presents a comparative study between new technologies and research trends to resolve heterogeneity issues of medical information systems.
Abstract-Web services are considered as one of the best and most widespread solution for handling the interoperability problem and the challenge of integration. The proliferation of Web services over the Internet becomes more and more significant. They are henceforth playing an important role in several fields such as ehealth, e-commerce and e-learning. Thus, one important question arises: how to manage Web services more efficiently? It is a key problem to the Web services based-applications at present especially that the need to enhance the Quality of Services (QoS) is constantly growing: the better the QoS are, the more the users are satisfied. This has spurred the study of scheduling algorithms for providing QoS guarantees.In this paper we put the light on the Web services requests scheduling strategies on the server side. In fact, we present a brief overview and a comparative evaluation of three queuing scheduling disciplines for Web services, which are: First in First out (FIFO), Priority Queuing (PQ) and Weighted Fair Queuing (WFQ). Then, we put forward a new scheduling strategy based on two wellknown strategies namely:Priority Queuing and Weighted Fair Queuing. The experimental results highlight the merits and shortcomings of each scheduling discipline in addition to its performance in terms of: execution time, communication time and response time.
This article describes how Web services play an important role in several fields such as e-commerce and e-health. As the number of Web services is increasing rapidly, finding the best Web service according to users' requirements becomes more challenging. The traditional method of Web service discovery is based on keyword match. Due to this, many Web services which are most relevant to the user request are left undiscoverable. Some other emergent approaches are based on semantics to improve the quality of the discovered Web services in terms of relevance and satisfaction of user's need. In this paper, the authors present a survey of existing semantic Web services discovery approaches giving priority to relevant ones. Furthermore, this paper provides a critical and comparative analysis of the studied approaches and stands out major challenges to be addressed to substantially enhance the semantic Web service discovery.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
