Semantic web services : advancement through evaluation
In the bioinformatics community, we can find a great variety of ontologies. However, as most of popular bioinformatics ontologies such as GO Gene Ontology, http: Without the formal logic support, it is also rather difficult, if not impossible, to implement advanced ontology reasoning services in order to support some more efficient usages of ontologies, e. Similar to myGrid http: First of all, we adopt the W3C ontology standard OWL to develop application specific ontologies, which are essentially the subsets of some popular bioinformatics ontologies such as GO and SO but newly provided with the formal logic representation.. This is mostly motivated by the fact that LP reasoners have been well researched in the past years and we have got an excellent LP reasoner OntoBroker http: Second, we adopt a distributed and modularized ontology structure which is one of the key best practices in the SW community, but not yet fully acknowledged in the semantics enabled bioinformatics system design. Besides these principal ontologies, we also plan to reuse some cross-domain ontologies such as vCard, Dublin Core, DAML security and privacy ontology http: As an immediate benefit of such a distributed and modularized ontology structure, the SIMDAT Pharma ontologies can independently be developed and maintained by different project partners. They can also easily be distributed into different repositories independent of specific ontology usages and reasoning services.

This functionality is usually provided by matchmaking capabilities which may themselves be deployed as services, brokers or middle agents that select the services that are closest to a requested service on the basis of a declarative characterization of the capabilities of both service requested and services provided. More generally, resource retrieval extends the notion of service matchmaking to the process of discovering any kind of Web resources ranging from services, data, information, knowledge to networked physical objects, persons and organizations for given application settings and purposes.
It is at the core of several scenarios in the Semantic Web area, spanning from Web services, Grid computing, and Peer-to-Peer computing, to applications such as e-commerce, human resource management, and social networking applications. The primary objective of this workshop is to bring together academic and industry researchers and industry practitioners who tackle semantic service matchmaking and discovery from various points of view.
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.
Or, get it for Kobo Super Points! See if you have enough points for this item. Numerous description languages, frameworks, tools, and matchmaking and composition algorithms have been proposed. Nevertheless, when faced with a real-world problem, it is still very hard to decide which of these different approaches to use. In this book, the editors present an overall overview and comparison of the main current evaluation initiatives for SWS.
The presentation is divided into four parts, each referring to one of the evaluation initiatives. The introduction to each part provides an overview of the evaluation initiative and overall results for its latest evaluation workshops. The following chapters in each part, written by the participants, detail their approaches, solutions and lessons learned. This book is aimed at two different types of readers.
Schema-based Semantic Matching: Algorithms, a System and a Testing Methodology
A service description or capability request that is submitted to some individual or intermediary e. A description of a desired service. Result of a negotiation process if successful? Condition involving predicates on any combination of these states: A description of a service in terms of a what is required by the service in order that it can execute successfully, and b what is generated by the successful execution of the service.
This includes data elements i.
The proposed algorithm is based on semantic distance measuring between the request (R) and the tested semantic web service (S). The output of the algorithm is not a matchmaking decision; it is a number that is called semantic distance measuring between R and S (sdmRS).
To further that effort, today we are introducing similarity search on Flickr. In many ways, photo search is very different from traditional web or text search. First, the goal of web search is usually to satisfy a particular information need, while with photo search the goal is often one of discovery; as such, it should be delightful as well as functional. We have taken this to heart throughout Flickr.
Second, in traditional web search, the goal is usually to match documents to a set of keywords in the query. That is, the query is in the same modality—text—as the documents being searched. Photo search usually matches across modalities: Text querying is a necessary feature of a photo search engine, but, as the saying goes, a picture is worth a thousand words. And beyond saving people the effort of so much typing, many visual concepts genuinely defy accurate description.
The similarity pivot is a significant addition to the Flickr experience because it offers our community an entirely new way to explore and discover the billions of incredible photos and millions of incredible photographers on Flickr. And there are many others that you might imagine as well. What notion of similarity is best suited for a site like Flickr?
This requires a deep understanding of image content for which we employ deep neural networks. We have been using deep neural networks at Flickr for a while for various tasks such as object recognition, NSFW prediction, and even prediction of aesthetic quality.

Add to basket Add to wishlist Description Over the last decade, a great amount of effort and resources have been invested in the development of Semantic Web Service SWS frameworks. Numerous description languages, frameworks, tools, and matchmaking and composition algorithms have been proposed. Nevertheless, when faced with a real-world problem, it is still very hard to decide which of these different approaches to use. In this book, the editors present an overall overview and comparison of the main current evaluation initiatives for SWS.
Abstract: In this paper, we mainly propose some matchmaking algorithms of Semantic Web service based on OWL-S to facilitate the comparison of input and output within service requestor and service provider, and thus lead to more accurate matchmaking.
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.
As expected, SW had also its effect on WS technologies and theory. These technologies provide means of describing in detail the service capabilities, execution flows, policies and other related information. Moreover, these technologies have given a new boost to service discovery and service composition research as new fields for experimentation have emerged .
Matchmaking of semantic service descriptions is a key technique for realizing discovery that aims at judging whether a located service is relevant compared to a given request . Many impediments face efficiency of any matchmaking algorithm. Here a common universal ontology, such as Word Net , should be used by matchmaking algorithm to discover WS.

Most commonly, it occurs when the new readers stop utilizing the eBooks as they are unable to use all of them with the proper and effective style of reading these books. There present variety of reasons behind it due to which the readers quit reading the eBooks at their first most effort to utilize them. Nonetheless, there exist some techniques that may help the readers to truly have a nice and successful reading encounter. A person ought to adjust the proper brightness of display before reading the eBook.
It is a most common problem that almost all of the folks generally bear while using an eBook.
Based on the Semantic Web Service framework, semantic matchmaker, specification matching and probabilistic matching, this paper proposes a fuzzy matchmaking approach for Semantic Web Services to support a more automated and veracious service discovery process in collaborative manufacturing environments.
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.

Look up in Google Scholar Abstract Semantic Web Services SWS aim at the automated discovery, selection and orchestration of Web services on the basis of comprehensive, machine-interpretable semantic descriptions. However, heterogeneities between distinct SWS representations pose strong limitations w. Hence, semantic-level mediation, i. In that, semantic-level mediation requires to identify similarities across distinct SWS representations.
Since current approaches to mediate between distinct service annotations rely either on manual one-to-one mappings or on semiautomatic mappings based on the exploitation of linguistic or structural similarities, these are perceived to be costly and error-prone. We propose a mediation approach enabling the implicit representation of similarities across distinct SWS by grounding these in so-called Mediation Spaces MS.

This work aims to resolve issues related to Web Service retrieval, also known as Service Selection, Discovery or essentially Matching, in two directions. The algorithm is hybrid in nature, combining novel and known concepts, such as a logic-based strategy and syntactic text-similarity measures on semantic annotations and textual descriptions. A plugin for the S3 contest environment was developed, in order to position Tomaco amongst state-of-the-art in an objective, reproducible manner.

Annotations can be exported in OWL-S. ASSAM is still under development and should be seen as a “technology preview”, not an industrial-strength application. Download and detailed instructions on http: Jaeger, Technische Universitaet Berlin The matcher demonstrates another algorithm that outputs different degrees of matching for individual elements of DAML-S descriptions. In detail, the algorithm considers elements of the service profile. With ranking a criterion is available to select a service among a large set of results.
Consider the result of flat matchmaking that consists of a set of matching and another set of non-matching services. If an autonomous system must still choose one of the set of matching services. An ordered list of services provides a decision support to autonomously choose the best servicepossible. Rama Akkiraju, IBM Research As the set of available Web Services expands, it becomes increasingly important to have automated tools to help identify services that match a requester’s requirements.
Finding suitable Web Services depends on the facilities available for service providers to describe the capabilities of their services and on the facilities available for service requesters to describe their requirements in an unambiguous and machine-interpretable form.
