A very selective summary 4. Mashup is not simply about the AJAX technologies, rather, it is typically related to reuse the data and other services from other web side and web applications. There are many ways to build up the mashup. This half-day tutorial will focus on using XML and JSON format of data and service and will introduce the following to the participants: What Mashup is about. The existing Mashup web sites and applications. The Mashup design and architecture which include the client-side mashups and server-side mashups. The existing mashup technologies. At the completion of this tutorial, participants will learn the latest mashup trends and how to architecture, build and manage the Mashup by using the existing tools, data and services for their applications.

A Similarity

The AWSCS is a system to implement different approaches for automatic composition of Web services and also to execute the resulting flows from these approaches. Aiming at demonstrating the results of this paper, a scenario was developed, where empirical flows were built to demonstrate the operation of AWSCS, since algorithms for automatic composition are not readily available to test. The results allow us to study the behaviour of running composite Web services, when flows with the same functionality but different problem-solving strategies were compared.

Furthermore, we observed that the influence of the load applied on the running system as the type of load submitted to the system is an important factor to define which approach for the Web service composition can achieve the best performance in production.

Therefore, enhancing web service discovery WSD method will improve the searching performance. In this paper, we firstly discuss and review some existing web service discovery approaches and identify their limitations. Subsequently, we propose a web service discovery method for cloud-based mobile application by using multi-level clustering technique to improve performance by reducing the searching scope. Our web service discovery architecture is able to increase the discoverability of more accurate web services based on user’s preferences.

Meanwhile, user preference Quality of Services QoS attributes are also used for ranking procedure to allow user to decide the quality of the mobile application. The experimental results show that our approach is able to increase the searching performance and provide a reliable list of selection for users.

Abstract Service matching aims to find the information similar to a given query, which has numerous applications in web search. Although existing methods yield promising results, they are not applicable for transportation.

In this paper, we propose a multilevel matching method based on semantic technology, towards efficiently searching the traffic information requested.

It determines three kinds of semantic service similarity with a given service request, that are logic-based, text-based and structural similarity. Among others, one goal of these additional descriptions is to support intelligent agents in automated service selection, a task which is hard to accomplish using pure syntactic information of service profiles based mainly on XML-Schema definitions. Typical application scenarios that require or benefit from a service matchmaking component include for example negotiation and coalition forming among agents and automated or assisted service composition.

This is taken into account by the WSDL-Analyzer tool presented in [12] by means of measuring 1 2 http: It applies five logical matching filters and ranks service offers that share the same logical matching degree with respect to a given request according to their text similarity value. In addition, it learns the optimal aggregation of these different types of semantic matching to decide on the semantic relevance of a service to a given request.

The results of our experiments shows that all hybrid matchmaker variants outperform the single matching type variants logic-based or text or structural only in terms of precision, while the performance of all three hybrid variants do not significantly differ with respect to SAWSDL-TC1. The remainder of the paper is structured as follows.

Hierarchical Matching of Traffic Information Services Using Semantic Similarity

Semantic matching represents a fundamental technique in many applications in areas such as resource discovery, data integration, data migration, query translation, peer to peer networks, agent communication, schema and ontology merging. It using is also being investigated in other areas such as event processing.

In fact, it has been proposed as a valid solution to the semantic heterogeneity problem, namely managing the diversity in knowledge. Interoperability among people of different cultures and languages, having different viewpoints and using different terminology has always been a huge problem. Especially with the advent of the Web and the consequential information explosion, the problem seems to be emphasized.

People face the concrete problem to retrieve, disambiguate and integrate information coming from a wide variety of sources.

A Web Service Discovery Scheme Based In the second step, the matching for semantic Web Service is modeled using bipartite graph of the nodes defined based on the ontology. The scheme is evaluated in terms of speed and accuracy represented by preci-sion, recall rate, and F-measure.

UDDI provides limited search facilities allowing only a keyword-based search of businesses, services, and the so called tModels based on names and identifiers. This category-based keyword-browsing method is clearly insufficient. This improvement enables software agents or search engines to automatically find appropriate Web services via ontologies and reasoning algorithm enriched methods. However, the high cost of formally defining to the heavy and complicated services makes this improvement widespread adoption unlikely.

To cope with these limitations, we have developed a suite of methods which assesses the similarity of Web services to achieve matchmaking. In particular, we present a conceptual model which classifies properties of Web services into four categories. For each category, a similarity assessment method has been given.


This paper shows a matchmaking algorithm to discover Semantic Web Services that are satisfying client requirements. At least fifty percent average gain in search relevancy is obtained when our matchmaking algorithm is applied to WSs that are actually matching the chosen fuzzy semantic theme. Introduction One of the crucial steps in an efficient Web service search is to understand what users mean in their request.

The search request is usually in the form of natural language. The current popular search engines literally take the search input without much semantic interpretation and attempt to find WS that may contain all or some of the keywords in the input query. The idea of adding machineprocessable semantics to data, that lets computer to understand the information and therefore process it instead of the human user, was behind the evolution of Semantic Web SW.

It enhances the improved bipartite graph based web s ervice matching. But the different matcher may semantic web service composition using clustering and ant colony optimization. This novel architecture solved the It improves the improved Bipartite graph based matching by considering multiple similarity metric.

At the heart of most service discovery mechanisms is a matchmaking algorithm that matches a semantic query to a set of compatible web service advertisements. These advertisements also describe service semantics as a set of OWL-S terms. Most current matchmaking algorithms are based on semantic matching of input and output terms alone. However, a complete description of the service profile also includes preconditions and effects and in order to find a true match the matchmaker needs to match on these aspects of the advertisement as well.

In this paper, we make the case for augmenting existing matchmaking algorithms with preconditions and effects in the context of Web Services. Further, we propose an algorithm for condition matching that is layered on the top of input-output term matching that overcomes the limitations of existing work. Although the problem of condition matching is NP-Complete, we can overcome this limitation by using a set of heuristics that gives us results in polynomial time.

The matched response interface instance and Web service name that are stored in the matched Response column family can be obtained from column family response interface in ontology table. The last column family Request Inteface stores the request that belongs to the Web service producing the response interface in the matched Response. The Request Inteface can be obtained from the table, which mainly manages the interface information.

After fetching all matched interfaces, the next step is to find the matching relation among Web services by using Web service match algorithm called SBMWS as shown in Algorithm 1. Function Mapper key,value 2. Ouput wsn, matched Interface ; 3.

Each service advertisement is a direct instance of Service Profile,.Therefore, web service discovery based on service profile includes expression of profile instance and matching of user requirement and service advertisement.

Therefore, they cannot satisfy the requirements of automatic discovery, implementation, synthesis, monitoring and recovery of Web services. An XML based language which contains semantic information to describe Web services is required, so that Web services can understand each other on respective contents, functions and attributes.
