To recognize various relationships those exist between question and answer pair, measuring semantically is essential. We present study using a match maker algorithm for similarity measurement between question-answer pair. The study compares similarity measurement using match maker algorithm as against semantic similarity measure on Miller-Charles bench marked data set. This paper present study about different types of algorithm used to measure the semantic similarity between the words and those result compare with match maker algorithm.

The experiments on real datasets shows matchmaker algorithm works better than web-based semantic similarity measure. Because of some flaws of previous similarity measurement models, we extend the concept attributes and propose a method to measure the similarity based on the semantic unit. We use semantic units to express the concept meanings, and use the supporting degree to show the different contributions of different semantic units. By introducing the psychological knowledge of the relevance, the resemblance, and the non-symmetry of similarity, we measure the similarity of concepts successfully.

We treat relation as particular concept, and we find a new method to measure the ontology similarity successfully based on semantic units.

Finally, our experiments prove that our results are more reasonable, and it is better than other methods. We should do service scheduling in pervasive environments. By comparing some present resource scheduling methods and discussing the importance of combining the market mechanism with semantic, we propose a model of service scheduling based on market mechanism and semantic Market-Semantic. By designing a new method to measure the similarity between ontology, and by looking on the ratio of capability and cost as the utility functions, we explore a method of service scheduling by which users not only can get the service satisfied, but also the resource can be allocated efficiently, Finally, the experiment proves that our method is better than the methods of Max-Semantic and Semantic-Cost-Max-Min.

A framework for expressing semantic relationships between multiple information systems for cooperation. After many years of information systems development, most private and public organizations are characterized by the presence of multiple information systems, possibly distributed and heterogeneous. Heterogeneity is generally related to representation languages, support technology, and evolution strategies. The result can be a deep disintegration of data and processes spread in several information systems.

Methods and tools for the analysis and comparison of the existing information systems are required, to identify replication, overlapping, bad distribution of data and processes among the existing systems, to set the basis for reengineering activities. This paper proposes computer-based techniques for the analysis of multiple information systems. Following an inherently data-oriented approach, conceptual descriptions of processes are analyzed focusing on characteristics of data manipulated and exchanged and on operations performed by processes.

The proposed techniques rely on similarity criteria and metrics and on a semantic dictionary, where the knowledge on process data and operations is properly organized. Experimental results of applying the analysis techniques to the information systems of the Italian Public Administration are discussed. Ontologies play a relevant role to support service match- making in the discovery process. In fact, the elements used for service capability description refer to concepts that can be properly defined and semantically related in domain ontologies. Semantic relationships be- tween concepts are then exploited to establish the type of matching be- tween advertisements and requests.

Hybrid ontology-based matchmaking for service discovery

In this paper we propose an ontology- based approach to service discovery characterized by a hybrid multimode matching, that is, a deductive capability matching extended with a flex- ible similarity evaluation scheme. In the approach, the semantic service description results from the cooperation of several components: The proposed approach provides service advice at multiple levels of granularity and rates adviced services according to different kinds of comparison strategies. An important objective of the Semantic Web is to make Electronic Commerce interactions more flexible and automated.

To achieve this, standardisation of ontologies, message content and message protocols will be necessary. In this paper we investigate how Semantic and Web Services technologies can be used to support service advertisement and discovery in ecommerce. In particular, we describe the design and implementation of a service matchmaking prototype which uses a DAML-S based ontology and a Description Logic reasoner to compare ontology based service descriptions. By representing the semantics of service descriptions, the matchmaker enables the behaviour of an intelligent agent to approach more closely that of a human user trying to locate suitable web services.
