Web services synchronization health care application
With the advance of Web Services technologies and the emergence of Web
Services into the information space, tremendous opportunities for empowering
users and organizations appear in various application domains including
electronic commerce, travel, intelligence information gathering and analysis,
health care, digital government, etc. In fact, Web services appear to be s
solution for integrating distributed, autonomous and heterogeneous information
sources. However, as Web services evolve in a dynamic environment which is the
Internet many changes can occur and affect them. A Web service is affected when
one or more of its associated information sources is affected by schema
changes. Changes can alter the information sources contents but also their
schemas which may render Web services partially or totally undefined. In this
paper, we propose a solution for integrating information sources into Web
services. Then we tackle the Web service synchronization problem by
substituting the affected information sources. Our work is illustrated with a
healthcare case study.Comment: 18 pages, 12 figure
A Data Warehouse Assistant Design System Based on Clover Model
Nowadays, Data Warehouse (DW) plays a crucial role in the process of decision
making. However, their design remains a very delicate and difficult task either
for expert or users. The goal of this paper is to propose a new approach based
on the clover model, destined to assist users to design a DW. The proposed
approach is based on two main steps. The first one aims to guide users in their
choice of DW schema model. The second one aims to finalize the chosen model by
offering to the designer views related to former successful DW design
experiences.Comment: 15 Pages, IJDM
A Model Based Metaheuristic for Hybrid Hierarchical Community Structure in Social Networks
In recent years, the study of community detection
in social networks has received great attention. The hierarchical
structure of the network leads to the emergence of the convergence
to a locally optimal community structure. In this paper, we aim
to avoid this local optimum in the introduced hybrid hierarchical
method. To achieve this purpose, we present an objective function
where we incorporate the value of structural and semantic similarity
based modularity and a metaheuristic namely bees colonies algorithm
to optimize our objective function on both hierarchical level divisive
and agglomerative. In order to assess the efficiency and the accuracy
of the introduced hybrid bee colony model, we perform an extensive
experimental evaluation on both synthetic and real networks
Ontologies for location based services quality enhancement: the case of emergency services
A good health rescue system is primarily based on a good emergency management. Therefore, physicians in general and mobile ones in particular have to react promptly and efficiently to save human lives and help people with serious or life-threatening conditions especially if they are called to treat them far from medical institutions. Taking effective and swift actions to reach the patient and/or the medical institution in time may help to reduce serious problems, and consequently improve the chances of patient cure and/or survival that present the primary concern of the physician. To overcome the emergency management limits of nowadays, this paper propose a medical assistance system based on ontologies that manage and exploit the large and rapidly growing volume of medical data in order to facilitate the on road decision making for the mobile physician. This work, more than determining the nearest health care institution, answers to the physician needs to distinguish whether the closest health care institution have the necessary medical resources (Equipments, services, staff etc.) and whether these resources are available to fulfill the patient needs
