Modeling, Matching and Ranking Services Based on Constraint Hardness [chapter]

Claudia d'Amato, Steffen Staab
2006 Lecture Notes in Computer Science  
A framework for modeling Semantic Web Service is proposed.  ...  Hard and Soft Constraints. Semantic service discovery can be performed by matching DL descriptions, expressing both Hard and Soft constraints, and exploiting DL inferences.  ...  By reusing a common vocabulary, service modelers can produce semantic service descriptions that can be shared and understood on the Web.  ...

Web Service Discovery Based on Unified View on Functional and Non-functional Properties

Martin Junghans, Sudhir Agarwal
2010 2010 IEEE Fourth International Conference on Semantic Computing  
We present how desired combinations of properties are specified and interpreted as a set of desired service descriptions and show how service descriptions that fulfill such constraints are discovered.  ...  In our formal model of Web services, we have a unified view on properties that characterize functional as well as non-functional aspects.  ...  In Section II we present our extended formal model of Web services and a syntax for describing Web services together with its semantic as a mapping to the formal model.  ...

Requirements for QoS-Based Web Service Description and Discovery

Kyriakos Kritikos, Dimitris Plexousakis
2009 IEEE Transactions on Services Computing  
Automatic discovery of Web Services (WSs) can be achieved by incorporating semantics into a richer WS description model (WSDM) and the use of Semantic Web (SW) technologies in the WS matchmaking and selection  ...  The goal of Service Oriented Architectures is to enable the creation of business applications through the automatic discovery and composition of independently developed and deployed (Web) services.  ...  ; • perfect matches are the QoS offers that satisfy all the requester's QoS hard and soft constraints; • partial matches are the QoS offers that satisfy all the hard constraints and zero or more soft constraints  ...

Semantics enhanced Services: METEOR-S, SAWSDL and SA-REST

Amit P. Sheth, Karthik Gomadam, Ajith Ranabahu
2008 IEEE Data Engineering Bulletin  
Adopting to the SOA and semantic Web evolution, METEOR evolved into METEOR-S where S stands for services (or Service oriented Architecture) and semantics.  ...  Our third phase recognizes emergence of Web2.0 and the People Web along with use of microformats for associating metadata to Web resources, and so called light weight web services (RESTful services and  ...  Kunal Verma and other members of the METEOR-S project at LSDIS lab.  ...

Optimizing QoS-Aware Semantic Web Service Composition [chapter]

Freddy Lécué
2009 Lecture Notes in Computer Science  
For this we propose to use the semantic similarities between output and input parameters of web services.  ...  Ranking and optimization of web service compositions are some of the most interesting challenges at present.  ...  Maximizing the quality of service composition using this model is essentially a multi-objective optimization problem with constraints on quality of services and semantic links, which is known to be NP-hard  ...

2006 IEEE European Conference on Web Services  
Discovering Web Services based on logical matching of capabilities is a new requirement for Semantic Web Services which cannot be solved with traditional information retrieval (IR) techniques.  ...  This approach performs well in finding matches of intersection type, and it also provides possibilities to compare, rank and explain these matches.  ...  With its indexes OM helps the creators of Semantic Web Services to find relevant or similar information for the semantic modelling of web services.  ...
