This paper proposes a Semantic Web-based context ontological reasoning service for multimedia conferencing process management. When the chairman enters the basic conference information, the process will automatically select the appropriate means of notifications based on the conference time and the participant contact details. In this system, all types of multimedia conferencing processes are encapsulated...
Web services bring more conveniences for users and developers. However, it makes user face the problem of service information explosion. The personalized service recommendation solves the problem. This paper proposes a method to predicting the system reliability which bases on user context information in mobile computing environment. The method construct user behavior model by formatting user location...
Applications based on micro or web services have had significant growth due to the exponential increase in the use of mobile devices. However, using such kind of loosely coupled interfaces provides almost no guarantees to the developer in terms of evolution. Changes to service interfaces can be introduced at any moment, which may cause the system to fail due to mismatches between communicating parts...
Developing applications with intelligent context access capabilities is challenged by the difficulty of obtaining advanced context information. The complexity of the logic required for processing context information adds another barrier for developing advanced context-aware applications. In this research paper, we propose a solution that allows context information sharing and extension toward the...
Hiking a relevant web service in the current environment full of various options is similar to looking for a needle in a haystack. The best possible web service is the one that completely fulfills the required functions while satisfying the QoS requested by a user. In this paper, we introduce a new context-based solution based on QoS (Quality of Service) exploiting both functional and non-functional...
Much like semantic service specification, semantic specification of tasks in business processes is needed, e.g., for their formal verification. In addition to the specification of the pure effects of some procedural code, however, business context plays a major role for semantic task specification. Open questions are how to include the business context of a task in its semantic specification, and...
Enterprise integration is one of the crucial challenges faced by modern organizations. Existing effort to define Enterprise Integration Patterns (EIPs) helps organizations to build their integration processes. An EIP represents a regularity in mobile agent behavior designs. In a complex distributed environment, such as mobile context, EIPs are a large number of patterns that describes the interactions...
One of the main concerns of Cloud storage solutions is to offer the availability to the end user. Thus, addressing the mobility needs and device's variety has emerged as a major challenge. At first, data should be synchronized automatically and continuously when the user moves from one equipment to another. Secondly, the Cloud service should offer to the owner the possibility to share data with specific...
REST service are generally more appropriate for smartphones than its counterpart, SOAP. However, the flexibility, scalability and performance gained through REST services are never enough to meet the goal of addressing the complex and mobile relationships among people. That is, usability of the REST service must be enhanced for involving none-programmers to compose services on their smartphones thereby...
Privacy is an important issue that has raised particular concerns among many research areas. This issue dramatically increases with the proliferation of the Web services composition paradigm. This is mainly due to the high dynamism and untrustworthiness characteristics of the services to be composed, which impose high levels of risk on the interacting parties. Existing technologies for managing and...
Pervasive computing offers environments in which user needs or tasks are fulfilled without demanding their attention. Context-aware service composition is a central aspect to achieving this, in which services are discovered and composed in response to context to meet user needs. Since pervasive computing environments are inherently dynamic and heterogeneous, context-aware service composition is a...
Nowadays, composite service has led to a new challenge as there are various kinds of users and an increasing number of similar Web services. This challenge is to pick out the most appropriate composition for user requester. However, a composite service is determined by the quality of the involved Web services and some user preferences. Consequently, the best composition optimizes the QoS (Quality...
In this paper we present the results of a study that aims to evaluate the usability of three selected web services, based on eye-tracking and thinking aloud techniques. The gathered comments and observations, recapitulated and supported by particular measures, allow us to discover and describe typical user behavior pertaining to given tasks to solve.
Over the last decades, there has been a growing interest to Service Oriented Computing (SOC) especially in a mobile environement. Web Services are the most common form of services for implementing SOC. Service Composition is to create a new business process by composing several services in order to fulfill business goals that individual services cannot achieve. The massive use of web services in the...
The orientation towards web service technology gives a raise to huge number of functionally similar web services. Hence, quality of service is becoming more important and even essential in web service technology as a distinctive criterion. Generally providers have sufficient information about the really provided quality, however, clients don't. Service level agreements that define the relationship...
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...
the idea of Service-Oriented Computing (SOC) is to understand users' requirements for Service-Based Applications (SBAs). We propose an adaptation-centric approach which allows: (i) modeling users' requirements for Service-Oriented System with the MAP formalism using an Intentional Service Model (ISM); (ii) ontology and the aspect according to the contextual changes in order to inject it in the process...
Companies have increasingly distributed their teams to increase productivity and quality, and to reduce their costs in software development processes. This scenario has brought new challenges to effective collaboration and to enhance communication across peers. Pragmatic interoperability has been considered as one of the key requirements to tackle these challenges. However, there is lack of research...
Protecting (authorizing) access to individual web services has been explored in many research efforts. The focus of such research is to ensure that authorized users with appropriate credentials are able to access resources under controlled and authorized security. However, integrating and/or composing such services, e.g. through workflow environments in collaborative environments, remains an open...
Semantic location-based services (LBS) aims to provide intelligent LBS that can find and integrate various information to better meet user requirements in location-aware context. This paper argues that traditional approaches for semantic GIServices in the Cyberinfrastructure context could be extended into the LBS. After highlighting the distinguished features of semantic LBS, i.e. context semantics...
