This paper discusses the engineering of communities of Web services with emphasis on the social interactions that arise between these Web services and hence, can put some restrictions on their behaviors. Like service parks, communities gather Web services ...
Trust Assessment for Web Services Collaboration
Found in: Web Services, IEEE International Conference on
By Hamdi Yahyaoui
Issue Date:July 2010
pp. 315-320
We present in this paper a trust-based game theoretical model for Web services collaboration. The devised model is an application of the generic model about tasks allocation for agents, which is presented in [13]. We consider that a collaboration between W...
On the Synchronization of Web Services Interactions

Issue Date:May 2009
pp. 644-651
Examining interactions between Web services is of paramount importance to the success of service composition. We have previously proposed a 2-layer framework for modeling, analyzing, and managing these interactions. Interactions are assigned to two layers:...
A New Approach to Model Web Services' Behaviors Based on Synchronization
Found in: Advanced Information Networking and Applications Workshops, International Conference on
By Zakaria Maamar, Quan Z. Sheng, Hamdi Yahyaoui, Jamal Bentahar, Khouloud Boukadi
Issue Date:May 2009
pp. 43-49
This paper introduces a novel approach for modelling and specifying behaviors of Web services. This approach excludes Web services from any composition scenario and sheds the light on two types of behaviors: control and operational. The control behavior il...
Towards a BPEL model-driven approach for Web services security
Found in: 2012 Tenth Annual International Conference on Privacy, Security and Trust (PST)

By Mohammed Almulla,Hamdi Yahyaoui,Kawthar Almatori
Issue Date:June 2012
pp. 330-335
This paper investigates techniques for supporting individual users in choosing appropriate Web services according to their specific needs, and accessing their favorite Web services. It also examines the provision of visualization of Web services that can b...
A QoS-Based Fuzzy Model for Ranking Real World Web Services
Found in: Web Services, IEEE International Conference on
By Mohamed Almulla,Kawthar Almatori,Hamdi Yahyaoui
Issue Date:July 2011
pp. 203-210
With the increasing popularity of using Web services, Quality of Service (QoS) is becoming a significant concern for both service consumers and providers. Several models for considering functional and non-functional QoS requirements for the purpose of Web ...
Separating Operational and Control Behaviors: A New Approach to Web Services Modeling
Found in: IEEE Internet Computing
By Quan Z. Sheng, Zakaria Maamar, Hamdi Yahyaoui, Jamal Bentahar, Khouloud Boukadi
Issue Date:May 2010
pp. 68-76
The ability to develop flexible business applications is one of the ultimate objectives behind the use of Web services. Before taking part in such applications, each Web service should be modeled so that service engineers can monitor its execution and iden...
Reputation of Communities of Web Services - Preliminary Investigation

By Said Elnaffar, Zakaria Maamar, Hamdi Yahyaoui, Jamal Bentahar, Philippe Thiran
Issue Date:March 2008
pp. 1603-1608
Web services communities can be seen as virtual clusters that agglomerate Web services with the same functionality (e.g., FlightBooking). However, selecting a community to deal with is a challenging task to users and providers. Reputation, besides other se...
On Checking the Compatibility of Web Services? Policies
Found in: Parallel and Distributed Computing Applications and Technologies, International Conference on
By Zakaria Maamar, Quan Z. Sheng, Hamdi Yahyaoui, Djamal Benslimane, Fenglin Liu
Issue Date:December 2007
pp. 125-130
This paper discusses the compatibility issue between policies of Web services, which could refrain the auto- matic composition of these Web services from smoothly progressing. Policies regulate/constrain the functioning of Web services at three levels iden...
