Mobile applications today face the challenges of increasing information, diversity of users and user contexts, and ever-increasing variations in mobile computing platforms. They need to continue being a successful business model for service providers and useful to their user community in the light of these challenges. An appropriate representation of information is crucial for the agility, sustainability, and maintainability of the information architecture of mobile applications. This article discusses the potential of the Semantic Web (Hendler, Lassila, & Berners- Lee, 2001) framework to that regard. The organization of the article is as follows. We first outline the background necessary for the discussion that follows and state our position. This is followed by the introduction of a knowledge representation framework for integrating Semantic Web and mobile applications, and we deal with both social prospects and technical concerns. Next, challenges and directions for future research are outlined. Finally, concluding remarks are given.

The Web

Purpose The success of web services involved the adoption of this technology by different service providers through the web, which increased the number of web services, as a result making their discovery a tedious task. The UDDI standard has been proposed for web service publication and discovery. However, it lacks sufficient semantic description in the content of web services, which makes it difficult to find and compose suitable web services during the analysis, search, and matching processes. In addition, few works on semantic web services discovery take into account the user’s profile. The purpose of this paper is to optimize the web services discovery by reducing the search space and increasing the number of relevant services. Design/methodology/approach The authors propose a new approach for the semantic web services discovery based on the mobile agent, user profile and metadata catalog. In the approach, each user can be described by a profile which is represented in two dimensions: personal dimension and preferences dimension. The description of web service is based on two levels: metadata catalog and WSDL. Findings First, the semantic web services discovery reduces the number of relevant services through the application of matching algorithm “semantic match”. The result of this first matching restricts the search space at the level of UDDI registry, which allows the users to have good results for the “functional match”. Second, the use of mobile agents as a communication entity reduces the traffic on the network and the quantity of exchanged information. Finally, the integration of user profile in the service discovery process facilitates the expression of the user needs and makes intelligible the selected service. Originality/value To the best knowledge of the authors, this is the first attempt at implementing the mobile agent technology with the semantic web service technology.

Semantic Web Services (SWS) aim at the automated discovery, selection and orchestration of Web services based on comprehensive, machine-interpretable semantic descriptions. The latter are, in principle, deployed by multiple possible actors (i.e., service providers and service consumers); thus, a high level of heterogeneity between distinct SWS annotations is expected. Therefore, mediation between concurrent semantic representations of services is a key requirement to fully implement the SWS vision. In this paper, the authors argue that “semantic-level mediation” is necessary to identify semantic similarities across distinct SWS representations. The authors formalize and implement a mediation approach based on “Mediation Spaces” (MS), which enables the implicit representation of semantic similarities among distinct SWS descriptions. As a result, given a specific SWS approach and the proposed MS, a general purpose algorithm is implemented to empower SWS selection with the automatic computation of semantic similarities between a given SWS request and a set of SWS offers. A prototypical application illustrates the approach and highlights the benefits w.r.t. current mediation approaches.

Stream Reasoning

State-of-the-art security frameworks have been extensively addressing security issues for web resources, agents and services in the Semantic Web. The provision of Stream Reasoning as a new area spanning Semantic Web and Data Stream Management Systems has eventually opened up new challenges. Namely, their decentralized nature, the metadata descriptions, the number of users, agents, and services, make securing Stream Reasoning systems difficult to handle. Thus, there is an inherent need of developing new security models which will handle security and automate security mechanisms to a more autonomous system that supports complex and dynamic relationships between data, clients and service providers. We plan to validate our approach on a typical application of stream data, on Wireless Sensor Networks (WSNs). In particular, WSNs for water quality monitoring will serve as a case study. The paper describes the initial findings and research plan for building a consistent security model for stream reasoning systems.

Semantic Web Service Composition

At present, more and more service providers carry on their business as a Web type. However, the function of individual Web services is very limited and the lack of semantic information, only can meet the needs for a single customer. In this paper, making Web services become an entities understood by the computer through introducing the concept of the Ontology. A framework of Semantic Web Service composition also is proposed based on Ontology for assembling basic Web services coming from different service providers and a solution is provided for to achieve value-added services based on a single service.

The phrase “Web Services (WSs)” are emerging as a creative scheme for furnishing the services to various immanent devices over the World Wide Web. The hasty intensification of the WSs applications and the availability of the vast count of the Service Providers create the certainty of selecting the “efficient” Service Provider by the consumers. The scenario Deduplication and Quality-of-Service (QoS) swears out as an objective to distinguish various Service Providers (SPs). The process of selecting proficient WSs / SPs, positioning and optimization of WSs Compositions are exigent dimensions of research with momentous entailments for the fruition of the “Web of Services” revelation. The term “Semantic WSs” follows appropriate semantic descriptions of WS functionality and a medium to facilitate programmed cogitating over WS Compositions (WSCs). The persisting model of the Semantic Web Services (SWSs) deals with the intriguing emerges like wretched forecast of best WSs and gemination of services with effective SPs, which heads to Quality level degradation on the Semantic Web. To deal the above identified issues, the anticipated research is planned to construct a model to manipulative the content similarities (semantic), consumption of a mixture of WSs and its corresponding SPs. After assessing these params, all the WSs are stratified on the basis of its consumption. Ultimately, the nominated scheme, selects the best and non duplicated copy of the WSs on the basis of its rating and placed it in the WSC. The process of detecting the duplicate copy would be performed by the Cryptographic Hash value of the Services. From the experimental annotations, it is recognized that our anticipated design amends the functionality of the SWSs in terms of Processor Utilization, Accessing Time, and its Space optimizations

Rdf Data

Semantic Web technologies are widely used for storing RDF data and making them available on the Web through SPARQL endpoints, queryable using the SPARQL query language. While the use of SPARQL endpoints is strongly supported by Semantic Web experts, it hinders broader use of RDF data by common Web users, engineers and developers unfamiliar with Semantic Web technologies, who normally rely on Web RESTful APIs for querying Web-available data and creating applications over them. To solve this problem, we have developed RAMOSE, a generic tool developed in Python to create REST APIs over SPARQL endpoints. Through the creation of source-specific textual configuration files, RAMOSE enables the querying of SPARQL endpoints via simple Web RESTful API calls that return either JSON or CSV-formatted data, thus hiding all the intrinsic complexities of SPARQL and RDF from common Web users. We provide evidence that the use of RAMOSE to provide REST API access to RDF data within OpenCitations triplestores is beneficial in terms of the number of queries made by external users of such RDF data using the RAMOSE API, compared with the direct access via the SPARQL endpoint. Our findings show the importance for suppliers of RDF data of having an alternative API access service, which enables its use by those with no (or little) experience in Semantic Web technologies and the SPARQL query language. RAMOSE can be used both to query any SPARQL endpoint and to query any other Web API, and thus it represents an easy generic technical solution for service providers who wish to create an API service to access Linked Data stored as RDF in a triplestore.

Ontology evaluation has become an important aspect for selecting suitable ontology to be used within a system. User such as services provider has been proposed with variety of methodology to help in selecting ontology from the Web. Ontology has been used by service providers to describe the semantic part of their web services profile. Evaluating domain ontology for semantic Web services descriptions is currently in its early phase. Moreover the building of domain ontology itself requires greater attention because the ontological element for semantic web services description is not standardized in the current knowledge and thus requiring further refinement. There are studies conducted on transforming Web Services Description Language (WSDL) format into Ontology Web Language for Services (OWL-S) types of ontology to improve the services discovery. But since then, the ontologies were stored and retrieve locally, as well as ranked based on its history of selection or popularity. Criteria for ontology evaluation were then proposed to help users to select the suitable ontology to describe their web services description by achieving certain criteria measurement. By far, the users have problems because the current WSDL description does not signify the services profile. Hence, our study proposes an ontology called OntoUji, which will be used within the process of domain ontology evaluation to suit the required description of semantic web services.

New Situation

The North Atlantic Treaty Organisation (NATO) is shifting towards Net-centric operations paradigms driven by the nature of the new missions that the Alliance will likely be facing in the coming years. This new situation has forced the Alliance to pursue the achievement of the so-called NATO Network-Enabled Capability (NNEC). In this framework, the concept of a system of systems should give way to the new paradigm of federation of services, where any capability needs to be seen as a loosely-couple service. From the perspective of any of these services, one of the biggest issues will be to discover available services and, more importantly, the information provided for such services can be consumed. For this purpose, we present in this chapter the use of Semantic Web as a technology that will facilitate the explicit description of the services available on the Net that will eventually help in selecting the right services. The technology will also mediate between service consumers and service providers, so information is given a well-defined meaning and is comprehensible. Based on the foundations of the Semantic Web, we propose a concept demonstrator called SISearch, where well defined vocabularies from apparently different domains are defined by using ontology languages. Then, these different vocabularies are interpreted with respect to the vocabulary defined by a potential service consumer. Assisted by this interpretation and by inference services, the SISearch will translate both consumer-based queries to service provider specific-queries (using different vocabularies), and aggregating and interpreting the results with respect to the service consumer vocabulary. This approach will allow extending to new potential service consumer or service providers without having to develop specific modules or components.
