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...
It is accepted that domain based development is playing an important role on IT projects today. Following such idea, this paper presents preliminary study results of a prototype architecture created with the purpose of using a domain-driven approach to shorten the development of software projects. Our discussion presents a way of sharing business domain models, developed in different project sites,...
Some of the characteristics that make service-oriented architectures appealing for enterprise applications also make them vulnerable to security breaches. The vulnerabilities are primarily due to the openness of the service-execution environment, to the dynamic run-time selection and composition of services, and to the autonomy of the individual services. In this paper, we describe these vulnerabilities...
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...
This paper addresses a methodology for developing the various user interfaces (UI) of a workflow information system (WIS), which are advocated to automate business processes, following a model-centric approach based on the requirements and processes of the organization. The methodology applies to: 1) integrate human and machines based activities, in particular those involving interaction with IT applications...
A critical success factor for enterprise application development is to get the systems specifications validated early in the planning and development process. Specification errors that are identified early on in the process are easier and less costly to fix. However, all too frequently business users only discover the impact of specifications once a system is deployed. It is therefore important to...
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...
There is a need for specialized search engines focused on specific disciplines that can use domain knowledge to guide the user to find exactly the resources they are searching for. In addition, these engines should be able search multiple and heterogeneous resource catalogs simultaneously and aggregate results from these catalogs. Noesis, a customizable search engine with semantic and resource aggregation...
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...
One of the challenges in SOA is to provide an efficient and effective way to select compatible Web service(s) and compose them into a functional service process that satisfies a user's needs. Moreover, the Web services(s) selected may be integrated with structures such as branches and merges to fulfill a task. This paper describes our system architecture and strategies on Web services composition...
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...
