In this work, we describe an approach for maintaining self-adapting personalized ontologies. We motivate this work with the observation that users are often interested in only small parts of larger domain ontologies; however, we also observe that users are frequently unaware of concepts that may be of interest given their past preferences. As such, we suggest that personalized ontologies should be...
Despite the evident benefits of semantic Web services, their widespread adoption by the industry is hindered by practicality issues. We see great promise in using proven Web 2.0 techniques to enable semantic Web services technologies to rise to their potential. We propose the social service network (SSN) - a framework integrating Web 2.0 social aspects to automatically enrich Web services with semantic...
Service-oriented architecture (SOA) has emerged as a promising paradigm for the inter-organizational sharing of domain-specific capabilities. Perhaps an equally important emergence is the use of SOA to manage the sharing of disparate information within a distributed environment. SOA provides a platform for organizations to enable the user-driven advertisement, discovery, and retrieval of data. A major...
This paper describes essential service and ontology design considerations for a multi-agent system. We will establish a context of basic information sharing and discovery for a combat search and rescue vignette. FIPA protocols and the OWL-S Task Model will be presented along with the associated work flow processes for our range of service options. A Protege-based ontology will convey our semantic...
An experimental prototype system was created and used to investigate how information relevant to analyst queries, and constrained by a contextual model, can be found over a large information space. Agents employing the ant model sift through documents quickly using a transductive support machine classifier and return those meeting a classifier which is constantly refined through feedback from semantic...
We present ISENS, a distributed, end-to-end, ontology-based information integration system. In response to a user's query, our system is capable of retrieving facts from data sources that are found in the surface semantic Web as well as inthe semantic Deep Web. Furthermore, it retrieves facts from sources where the data is not directly described in terms of the query ontology. Instead, its ontology...
IntegraL is a digital library system demonstrating a lightweight system integration technique for digital library collections and services. Digital library systems generally require integration with minimal or no changes to their code. IntegraL users see a totally integrated environment. They use their digital library system just as before. They also see extra link anchors. Selecting one generates...
In this experience report we present Business Process Illustration, a technique supporting experience-grounded validation of new business processes by subject matter experts.
Creating a service-oriented architecture requires the identification of services to be composed together in order to solve a given need. Currently, software engineers perform this design task by hand by identifying services and how to compose them. In this paper, we propose RuGCo a system to automatically compose Web services coming from a static large repository, according to a domain ontology expressed...
In this paper, we recognize the shortcomings of the current search engines that do not index and search the deep Web. We present requirements of a deep Web service search engine, that will lead to the query objects in the deep data sources. In order to realize the DWS search engine, we propose semantic metadata and annotation of deep Web services (DWS), a reasoning component to assess the relevance...
Ontologies could play an important role in assisting users in their search for Web pages. This paper considers the problem of constructing domain ontologies that support users in their Web search efforts and that increase the number of relevant Web pages that are returned. To achieve this goal, this paper suggests combining Deep Web information, which consists of dynamically generated Web pages, which...
The increasing competition in the mobile marketing market indicates that Mobile Marketing platform providers will be forced to integrate identity- and context information offered by the mobile network, in order to improve the efficiency of their applications. However, existing concepts/implementations only unassertively exploit available opportunities as well as insufficiently address emerging impacts...
The distribution of services spanning across organizational boundaries raises problems related to intellectual value that are less explored in current service oriented research. Being a way to manage the intellectual rights between service consumers and service providers, licenses are critical to be considered in services. A service license describes the terms and conditions for the use and access...
Web service is essential in achieving dynamic business process. With the dramatically increased number of Web services advertised in UDDI, Web Portal or Internet, how to locate the best Web service according to a user's requirement is becoming more and more important, which calls for efficient and effective Web service discovery mechanism. Considerable efforts have been attained in solving this problem...
Service-Oriented Architecture (SOA) is an effective paradigm for publishing common features as services and reusing the published services in building applications. Therefore, reusability of services is a key criterion for evaluating the quality of services. The evaluation target for reusability in our model is the service, applied to both atomic and composite service. Reusability models for conventional...
Internet systems are a typical scenario where sequences of interactions arise. Modeling the factors that drive the dynamics of an online auction, for example, is complex, since successive interactions become a loop-feedback mechanism, that we call reactivity, that is, the user behavior affects the auction negotiation and vice-versa. In this paper we briefly describes our methodology for characterizing...
We consider the problem of managing advertisements (or ads for short) for ad-hoc online videos, such as those generated by end users. We propose a novel ad selection approach based on video tags. We first compute intrinsic values of individual video tags to each ad, called ad-specific weights of tags. The computed weight of a tag indicates the relevance of the tag to a given ad. Then based on the...
Electronic commerce mechanisms are mainly investigated in two independent research areas: service-oriented computing (SOC) and multi-agent systems. The former as a means to deliver electronic services of various granularity and the latter as a testbed of electronic negotiation mechanisms. However, both research areas heavily rely on each other. On the one hand, service-oriented architectures need...
The goal of the Web Service Composition (WSC) problem is to find an optimal "composition" of web services to satisfy a given request using their syntactic and/or semantic features, when no single service satisfies it. In this paper, in particular, we study the WSC problem from semantic aspects, exploiting the supertype-subtype relationship among parameters, and propose a novel solutionbased...
As SOC and Web service technology become more widely used, large amounts of services need to be efficiently and effectively composed to meet complex businesses. In this paper, we proposed an approach to resolve the composition problem over large-scale services. We used an inverted table as index for a quick service discovery, and applied a service dependency graph (SDG) and an AND/OR graph as the...
