SAM: Semantic Advanced Matchmaker

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.

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.

With the increasing adoption of Web Services and service-oriented computing paradigm, matchmaking of web services with the request has become a significant task. This warrants the need to establish an effective and reliable Web Service discovery. Here reducing the service discovery time and increasing the quality of discovery are key issues. This paper proposes a new semantic Web Service discovery scheme where the similarity between the query and service is decided using the WSDL specification and ontology, and the improved Hungarian algorithm is applied to quickly find the maximum match.

The proposed approach utilizes the structure of datatype and operation, and natural language description used for information retrieval. Computer simulation reveals that the proposed scheme substantially increases the quality of service discovery compared to the existing schemes in terms of precision, recall rate, and F-measure. Moreover, the proposed scheme allows consistently smaller discovery time, while the improvement gets more significant as the number of compared parameters increases.

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.

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.

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.. DOI: Semantic Web service discovery: state-of-the-art and research challenges.

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.

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.
