The main purpose of OLAP projects is to consolidate and aggregate operational system data, allowing thus measuring, analyzing and help in decision-making. Nevertheless, such systems are rarely linked to their business context, goals or objectives that enterprise wishes to achieve, and metrics such as Key Performance Indicators (KPIs) to evaluate the degree of their satisfaction. Indeed, KPIs are measurements...
Service Composition is playing a pivotal role in diverse industries to approach more cost effective solutions in an efficient manner. Web service selection is playing a key role in the domain of the composition and it considers as the most important last informant of successful Automatic service composition. Since it is growing the web services in tremendous speed due to the innovation of cloud computing...
Quality of Experience has become a significant parameter in evaluating and rating video services. This paper presents the impact of gender on the Quality of Experience for video services. Initial results from subjective tests show that male viewers requested higher video quality compared to female viewers, while female viewers concentrated more on the contents of the video.
Services providers and requestors, in ubiquitous environments, are characterized by the heterogeneity of their devices and the constant changing of the network bandwidth. These characteristics pose a big challenge to service selection methods. This paper describes a new service selection method based on Multiple Linear Regression (MLR) techniques. In order to ensure the selection of the best service...
User mobility has become a key attribute in the design of optimal resource allocation policies for future wireless networks. This has become increasingly apparent in cognitive radio (CR) systems where the licensed, primary users (PU) of the network must be protected from harmful interference by the network's opportunistic, secondary users (SU): here, unpredictability due to mobility requires the implementation...
To improve the inter-working of future 5G systems with existing technologies, this paper proposes a novel context-aware user-driven framework for network selection in multi-RAT environments. It relies on fuzzy logic to cope with the lack of information usually associated with the terminal side and the intrinsic randomness of the radio environment. In particular, a fuzzy logic controller first estimates...
Cloud federation is a group of aggregated providers, who are mutually cooperating and collaborating to share their resources in order to improve each other services. It has lured the attention of commercial industries towards itself for its effective utilization of cloud resources. Effective management of the resource is very much required in order to increase the profits of an individual service...
O2O (Online to Offline) is a new type of e-commerce model. Traditional recommendation methods focus on commodity rather than service, and lack the consideration on customer context and service status. In order to improve the quality of O2O service recommendation, this paper proposes an O2O service recommendation algorithm based on customer context and trust service. The method mainly includes two...
This paper describes a Semantic Version Management method that enables managing consistently digital resources throughout their life cycle. The core notion is that resources are described be means of logical specifications formally expressed using an extensible logical language. A new version is considered certified only if the resource owner is able to formally prove that it satisfies its logical...
In this position paper we identify the design of “wise systems” as an open research problem addressing new technology-based systems. Increasing complexity and sophistication make those systems hard to understand and to master. Human users are very often involved in learning processes that capture all their attention while being of little interest for them. To alleviate human interaction with such...
Trust is the cornerstone of success in any relationship between two or more parties. Current technologies to include cloud computing, social networking, and mobile applications, coupled with the explosion in storage and processing power, are evolving large-scale marketplaces for a wide variety of resources and services. In such marketplaces, users (consumer, provider and broker) are largely autonomous...
For the matching relation between the logistics cloud service and logistics task in cloud logistics systems, the description method of logistics cloud service based on context was proposed. Firstly, build the concept model of logistics cloud service, then designed cloud logistics domain context ontology and analyzed the description of logistics cloud service by introducing the definition of context,...
Learning service selection in context-aware ubiquitous learning systems is affected not only by human errors, those of sensors but also by the dynamic aspect of these systems. The service selection in these systems is based on the learner QoS requirements, needs. However, these latter are based on vague linguistic terms which should be represented by fuzzy set theory. To this end, we have proposed...
Traffic demand increases explosively due to the developed services and it becomes the mobile network's load. One of these services, social networking, generates a large amount of traffic. To solve it, we propose a small cell offloading algorithm using social context. In the proposed algorithm, to satisfy the effective data rate maximally, we estimate the application selection probability using social...
Non functional requirements are very interesting specially in case of business relationships. In fact they are idioms of communication between business environment parties: provider and consumer. In particular in web services context, these requirements and non functional characteristics are also seen as a ranking and selection criteria. Thus, many researchers propose tools to measure the quality...
This paper proposes an eHealth context management and distribution architecture with semantic features and designed for the Future Internet. A formal basis was used for managing both QoC (Quality of Context) and QoS (Quality of Service). Our approach was assessed in an experimental setting by using biomedical and environment sensors. The experiments showed that the context semantic processing detects...
This paper proposes an architecture for managing and distributing context information from an AAL (Ambient Assisted Living) environment to the cloud. The architecture, with semantic features, includes the processing of the sensed data using QoC (Quality of Context) parameters and data transport using SDN (Software-defined Networking). The experiments showed that the semantic context processing allows...
During the last decades, we assisted to what is called “information explosion”. With the advent of the new technologies and new contexts, the volume, velocity and variety of data has increased exponentially, becoming what is known today as big data. Among them, we emphasize telecommunications operators, which gather, using network monitoring equipment, millions of network event records, the Call Detail...
The fast growth of the number of deployed Web services is transforming the enterprises from data-oriented systems into service-oriented systems. In this context, the selection of the best web service that satisfies specific QoS values among a group of web services with similar functionalities is becoming a challenging issue. To this aim, we investigate in this paper a methodology for web service selection...
The trend of grid computing available on the Internet has generated challenges to the allocation of resources provided by this type of environment. Considering the user's satisfaction, many of these challenges can be solved by the quality of experience paradigm that takes into account several context parameters. Considering the resources utilization, the quality of context paradigm can be used to...
