The historical records of mechanical fault contain great amount of important information which is useful to identify the similar fault, but the structural representation and the knowledge reasoning problem are troubled that we use the historical records effectively. Aiming at the problem, the fault knowledge representation based on ontology is put forward out. Firstly, the knowledge characteristics, the ontology building significance and principle of fault are analyzed. Secondly, the fault ontology is defined and described. The case study shows that the fault knowledge representation based on ontology is very intuitive and efficient; it can provide us a novel way to deal with the fault diagnosis problem. At the moment, the flexibility of the workflow definition language is not enough, various products lack operation quality between each other, and the compatibility is bad. Aiming at this situation, this thesis defines one kind of workflow model with component based on XPDL, which causes pattern description and process definition to be simply, and enables the separation between process definition and performing to become possible, so that it can truly realize the universal process definition, communication and interpretation. This paper introduces a new method for the communication between human and product model entity definition processes. As product definition is moving into modeling in industrial product lifecycle management PLM systems, and built-in knowledge and intelligent computing content of product models increase, development of product modeling faces new challenges. More often, knowledge content is not in accordance with authorized human intent and different intents of different authorized humans for the same task are not in harmony.

The description of the behavior of the requested web service and the description of the behavior of the computing service conform to a description logic. Based on logical rules of the description logic, it is determined that the description of the behavior of the existing computing service is subsumed by the description of the behavior of the requested web service. For example, users may implement or access a software application to obtain a stock quote or an airline reservation, or to manage aspects of a business enterprise.
Particular functions of software applications may be implemented as more or less discrete components, and may thereby be used in a variety of contexts.

In this article, we propose a semantic service matchmaking algorithm that ﬁnds AEs offering the requested management functions based on the subsumption relationships of inputs, outputs, preconditions and effects (IOPEs) of the service has long been a topic of interest in the context of the semantic web, and more speciﬁcally semantic web.
Nowadays, many tourists plan their trips in advance using the information that is available on web pages. Cities compete against each other to offer the most attractive and complete information and services through the tourism section of their web sites. However, this often leads to information-bloated and multimedia-rich web sites which are similar to digital versions of printed brochures.
Everyone receives the same information, regardless of their interests. This is unlike when they visit a tourism office, and receive customized information and recommendations based on their profile and desires. CRUZAR is a web application that uses expert knowledge in the form of rules and ontologies and a comprehensive repository of relevant data instances to build a custom route for each visitor profile.
There are a number of reasons that make this city an excellent test bed for such as project. Zaragoza is one of the biggest cities in Spain, and it enjoys a very dynamic cultural agenda, as well as frequent top-level sport events. Finally, the city council has extensive databases with all the aforesaid information, including content in five languages. Technical details of the solution The first challenge of our use case in the eTourism domain was to collect the required data from existing relational databases which are used to feed the content of the Official Website of Zaragoza.
A Semantic Model for Matchmaking of Web Services Based on Description Logics
Di Noia , E. Di Sciascio , F. Donini Submitted on 12 Oct Abstract: Matchmaking arises when supply and demand meet in an electronic marketplace, or when agents search for a web service to perform some task, or even when recruiting agencies match curricula and job profiles. In such open environments, the objective of a matchmaking process is to discover best available offers to a given request.
Semantic Web Services, which is the method purported to provide services for the convenience of users in the Semantic Web environment, is composed of SOAP, WSDL, UDDI and DAML-S. SOAP, used for calling Web Services, is a quantitative protocol for sending data that is structuralized and.

Abstract With smartphone distribution becoming common and robotic applications on the rise, social tagging services for various applications including robotic domains have advanced significantly.
Though social tagging plays an important role when users are finding the exact information through web search, reliability and semantic relation between web contents and tags are not considered. Spams are making ill use of this aspect and put irrelevant tags deliberately on contents and induce users to advertise contents when they click items of search results. Therefore, this study proposes a detection method for tag-ranking manipulation to solve the problem of the existing methods which cannot guarantee the reliability of tagging.
Similarity is measured for ranking the grade of registered tag on the contents, and weighted values of each tag are measured by means of synonym relevance, frequency, and semantic distances between tags. Lastly, experimental evaluation results are provided and its efficiency and accuracy are verified through them. Introduction As social networking services are becoming common and robotic technology has advanced, the number of social tagging services for various applications including robotic domainsis also rising.
A tagging service allows a user to enter a description of the contents of a resource using a simple term or an annotation.

Matchmaking Support for Mathematical Web Services Simone A. Ludwig1, William Naylor 2, Julian Padget and Omer F. Rana1 1School of Computer Science/Welsh eScience Centre, Cardiff University 2Department of Computer Science, University of Bath Abstract Matchmaking is one crucial tasks in agent-based systems and describes locating and identifying the most suitable services.
By adding constraints over aspects that the Seeker is interested in, the query can be used to filter out irrelevant advertisements. There are two kinds of queries that can be defined: The persistent query is a query that will remain valid for a length of time defined by the Seeker itself. The Host immediately returns matched advertisements that are currently present in the repository.
Within the validity period of the query, whenever a matching advertisement is added to the repository or an advertisement is modified so that it becomes a match , the Host will notify the Seeker with a new set of matched advertisements including those that have been changed or have been added. The persistent query is automatically removed when the validity period is ended. After the advertiser published his advertisement to the Host, the Host notifies an ID indicating the advertisement to the advertiser.
Later on, this ID is used between the Host and the advertiser to specify which advertisement is to be modified or withdrawn. There is an obvious security issue involved, but we simply assume that all the partners in this framework are trusted. It maintains an advertisement repository, where published advertisements are stored. In finding out about advertised services, browsing parties can make use of this information to tune the advertisements that they will submit in turn, so as to maximize the likelihood of matching.
The benefit of JADE is that we can concentrate on the agent functionalities and leave other things, like communication between agents, to the platform. Three kinds of agents have been implemented:

As a result, the motivation to develop a powerful and customizable matchmaking engine becomes a very important criterion. Using semantic information for the matchmaking process achieves better results than syntactic type matchmaking. In this paper an ontologybased service discovery tool, called OntoServiceMatchmaker, is presented which performs flexible semantic matches of customized service requests.
This engine utilizes current semantic matchmaking techniques to perform the service discovery. The description properties and functional attributes of the ontology are properties for the matching values. These properties found by the ontology parser and reasoned by the inference engine serve for the matchmaking process as input variables.
explored to make Web services ubiquitous with open plug-in interfaces. Automatic Web service discovery and matchmaking is the principal aspect for the dynamic service composition. The accuracy of the matchmaking process enhances the possibility of successful composition, eventually satisfying the user and application requirements.
The World Wide Web is changing. While once conceived of and implemented as a collection of static pages for browsing, it now promises to become a web of services–a dynamic aggregate of interactive, automated, and intelligent services that interoperate via the Internet. Multiple web services will interoperate to perform tasks, provide information, transact business, and generally take action for users, dynamically and on demand.
Such prospects are especially important for the e-business community, providing opportunities for conducting business faster, more efficiently, and with greater ease than ever before. For instance, the opportunity to manage supply chains dynamically, to achieve market advantage, is expected to increase productivity and add value to products.
On the other hand, automatic management of supply chains presents new challenges. In these pages, we present our Semantic Matchmaker, an entity that will allow web services to locate other services, provide a solution to the problem of matching, and allow for full implementation of interoperative service providers on the web. We show how semantic matching between advertisements and requests is performed.
Semantic Matchmaking for Web Services Discovery First, we focus on the problem of locating web services on the basis of the capabilities that they provide. The solution to this problem requires a language to express the capabilities of services, and the specification of a matching algorithm between service advertisements and service requests, one that recognizes when a request matches an advertisement. We adopt OWL-S as a service description language, because it provides a semantically-based view of of web services, including the abstract description of the capabilities of the service, the specification of the service interaction protocol, and the actual messages that it exchanges with other web services.
