Semantic Web Service Composition using Planning and Ontology Concept Relevance
Ourania Hatzi
A planning approach to compose services… very similar to our work: OWL-S to describe services, Pellet as semantic reasoner for OWL and a planner to compose services. The most interesting thing is not about services, but about semantic awareness when the planner fails.
Improving Web services adaptability thanks to a synergy between aspect programming and a multi-agent middleware
Flavien Balbo and Valérie Monfort
About enterprise IS. They add «aspects» to ws and use a middleware (agent-based) to improve adaptability. I don’t understand why all these mess: AOP to add dynamically new behavior to web services and agents just to coordinate (by communication) ws… I guess that using just one technology will be easier.
QoSS Policies Operating for Web Services within SOA
David Allison
QoSS: Quality of Security Service. Metadata includes information about authentication, authorization and privacy, embedded inside the SOAP message. I don’t know why to modify SOAP is needed instead of use the WS-Auth, WS-Privacy and so on, most of them provided by the service platforms. This can be useful for «private» service (inside an intranet, or for enterprise services), but not for public ones.
Building Blocks: Layered Components Approach for Accumulating High-Demand Web Services
Satoshi Morimoto, Satoshi Sakai, Masaki Gotou, Heeryon Cho, Toru Ishida, and Yohei Murakami
They use web services as language resources that can be combined to create new tools (A Language Grid). For example, multiple dictionaries. Building blocks for simple components programed in PHP or Java are encapsulated inside web services. This is used to create new systems (I assume that it’s used by programmers) faster than without them.
A framework to guarantee time-bounded composed services
Elena del Val.
Well, these is our paper, so I have no things to say…. it’s perfect :-D Ok, ok… I tell you something about that. The idea is to guarantee service execution time (soft real-time). Commitment Manager reach agreements with providers to get a temporal windows in which is ensured that the service will be provided. WS-Agreement protocol is used to do that.
Supporting Web Service Protocol Changes by Propagation
Ahmed Azough
About business protocols. They consider them as FSM and allow add and delete state, transitions and the final state.
Reasoning about Web Services with Local Closed World Assumption
Limin Chen, Hong Hu, and Zhongzhi Shi
Ups, no one for this paper, so we’ve finished
