As service oriented architecture SOA matures, service consumption demand leads to an urgent requirement for service discovery. In this paper, we introduce the concept of service context which is used to represent service usage. In query processing, both service content and service context are examined to identify services. We propose to represent service context by a weighted bipartite graph model. Based on the bipartite graph model, we reduce the gap between query space and service space by query expansion to improve recall. We also design an iteration algorithm for result ranking by considering service context-usefulness as well as content-relevance to improve precision.
Improved Matchmaking Algorithm for Semantic Web Services Based on Bipartite Graph Matching
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.
This approach is validated within a framework proposed at the end of this paper and compared with the greedy approach and the bipartite graph based matching..

In order to overcome the limitations of a syntax-based search, matchmaking algorithms based on semantic techniques have been proposed. Most of them are based on an algorithm originally proposed by M. Paolucci, et al. In this paper, we analyze this original algorithm and identify some correctness issues with it. We illustrate how these issues are an outcome of the greedy approach adopted by the algorithm.
INCREMENTAL MAINTENANCE OF ONTOLOGIES 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.
Therefore, the time efficiency of the service discovery can be improved compared with the general cluster-based method of service discovery. Nowadays, as SOA Service-oriented Architecture has been the main driving force for web application development, the types and number of web services grow rapidly.

Multi-Strategy Web Service Discovery for Smart Government
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.

“Improved Matchmaking Algorithm for Semantic Web Services Based on …”
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.

Semantic Web Service technology is the solution to system integration and business collaboration for smart government which is cross-border and heterogeneous on a large scale. However the tremendous Web services search space caused by the wide range, large scale and complex e-government business systems is one of the great challenges for smart government. The paper focuses on researches about service discovery in e-government business integration for smart government.
In accordance with the application environment and the current technical status of e-government, the author proposes a multi-strategy Web service discovery method on the basis of the proposed semantic model. The discovery process comprises three stages: keyword query with semantic enhancement, IO semantic matching and PE semantic matching. Finally similarity calculating method is proposed to evaluate the matching degree of each candidate service for service selection as well as the conclusions.
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.
Web Service Invocation: OWL-S along with the domain ontology specifies the invocation matching mechanism provided by UDDI and WSDL is no better than a simple string Notion of Flexible matching The semantic matchmaking algorithm should promote the Bipartite graph based matching.

UltiMatch-NL: A Web Service Matchmaker Based on Multiple Semantic Filters
An important component of the discovery process is the matchmaking algorithm itself. In order to overcome the limitations of a syntax-based search, matchmaking algorithms based on semantic techniques have been proposed. As a greater number of Web Services are made available, support for service discovery mechanisms become essential. So we have use the semantic matchmaking using the greedy approach, that work on the greedy concept.
