UltiMatch-NL applies two filters namely Signature-based and Description-based on different abstraction levels of a service profile to achieve more accurate results. More specifically, the proposed filters rely on semantic knowledge to extract the similarity between a given pair of service descriptions. Thus it is a further step towards fully automated Web service discovery via making this process more semantic-aware. In addition, a new technique is proposed to weight and combine the results of different filters of UltiMatch-NL, automatically. Moreover, an innovative approach is introduced to predict the relevance of requests and Web services and eliminate the need for setting a threshold value of similarity. The performance evaluation based on standard measures from the information retrieval field shows that semantic matching of OWL-S services can be significantly improved by incorporating designed matching filters.

SAM: Semantic Advanced Matchmaker
The original algorithm used in literature was proposed by Paolucci et al. Some research works, propose an extension or an improvement of this algorithm to correct the matchmaking used. In this paper we present an algorithm of matchmaking that resolves the problems of Paolucci algorithm by using the shortest path algorithm which determines the optimal matching between user query and provider service.
Bellur, U. and R. Kulkarni, Improved matchmaking algorithm for semantic web services based on bipartite graph matching.
A key challenge in building the Semantic Web is integrating heterogeneous data sources. This paper presents an incremental algorithm for maintaining integration in evolving ontologies. For example, an increased number of smaller, task oriented ontologies, are emerging across the Bioinformatics domain to represent domain knowledge; integrating these heterogeneous ontologies is crucial for applications utilizing multiple ontologies.
Most ontologies share a core of common knowledge allowing them to communicate, but no single ontology contains complete domain knowledge. Recent papers examined integrating ontologies using bipartite graph matching techniques. However, they do not address the issue of incrementally maintaining the matching in evolving ontologies. In this paper we present an incremental algorithm, OntoMaintain, which incrementally calculates the perfect matching among evolving ontologies and simultaneously updates the labels of the concepts of ontologies.
We show that our algorithm has a complexity of O n2 compared to complexity O n3 of traditional matching algorithms.

Improved Bipartite graph in the pre-processing and service discovery a graph-based method for discovering semantic web services via matching Matchmaking is then algorithm called as user preference based web service ranking.
As the number of available Web services increase finding appropriate Web services to fulfill a given request becomes an important task. Most of the current solutions and approaches in Web service discovery are limited in the sense that they are strictly defined, and they do not use the full power of semantic and ontological representation. Service matchmaking, which deals with similarity between service definitions, is highly important for an effective discovery.
Studies have shown that use of semantic Web technologies improves the efficiency and accuracy of matchmaking process. In this research we focus on one of the most challenging tasks in service discovery and composition: Service matchmaking. We introduce an efficient matchmaking algorithm based on bipartite graphs. We have seen that bipartite matchmaking has advantages over other approaches in the literature for parameter pairing problem, which deals with finding the semantically matching parameters in a service pair.
Our proposed algorithm ranks the services in a candidate set according to their semantic similarity to a certain request. Our matchmaker performs the semantic similarity assignment implementing the following approaches: Subsumption-based similarity, propertylevel similarity, similarity distance annotations and WordNet-based similarity.
Our results show that the proposed matchmaker enhances the captured semantic similarity, providing a finegrained approach in semantic matchmaking. Springer Professional.
Improved Matchmaking Algorithm For Semantic Web Services Based On Bipartite Graph Matching
Web service discovery has always been a hot issue in the research field of Web services. In this study, services are grouped into functionally similar service clusters through calculating semantic similarity with WordNet. A Concept Position Vector model of service clusters is proposed, which can sharply cuts in the number of services that do not completely match the service requests, thus can quickly build up the set of candidate services.

Clients search the registry to locate providers of the desired service. Today, in most cases,. As a result service discovery becomes an important task. Large number of services made discovery of web services is a critical one and also discovery process has the scalability issues when the number of services increases. In this work, we address the issue of scalability in web service discovery process by adding a preprocessing stage.
Our approach to preprocessing stage involves filtering the services by checking the details of descriptions; semantic- based web service discovery involves Bipartite Matching and semantic enhancement of the service request. Our approach proposes a preprocessing stage based on the details of descriptions that filter service repositories with enhanced service request.
We propose a solution for achieving functional level Bipartite Matching based on an Ontology framework. The semantic enhancement of the service request achieves a better matching with relevant services. The service request enhancement involves expansion of additional terms retrieved from WordNet that are deemed relevant for the requested functionality. An efficient matching of the enhanced service request with the filtered services is achieved utilizing Bipartite Matching.
Our Experimental results validate the effectiveness and feasibility of the proposed work. Loose coupling is an important principle underlying Service Oriented Architecture. One aspect of loose coupling is the ability to invoke a service with little or no knowledge about it.
