Accessibility of Public Web Services: A Distant Dream?
2013
Part 1: Long and Short Papers; International audience; Today, many public services are available online through Web sites. The accessibility of the sites, also to people with disabilities, is important because the accessibility concerns equality of citizens, a cornerstone of democracy. In the current study we carried out a meta-analysis of 17 studies concerning the accessibility of the Web sites of public administration. Furthermore, we assessed the accessibility of Web pages of 12 ministries of the Finnish government. The assessments were based on the Web Content Accessibility Guidelines (WCAG). The results showed that in terms of the WCAG guidelines, the average accessibility of public We…
Semantic web technologies for facilities management
2007
Facility management is the practice of coordinating the physical workplace with the people and work of the organization. It integrates the principles of business administration, architecture and the behavioral and engineering sciences. To deal with these requirements, we have developed a framework based on Semantic Web technologies: RDF, OWL, SWRL and named graph. This framework, called C-DMF, allows facilities manager to organize all knowledge generating during building lifecycle in end-user contextual graphs.
Ontology languages for the semantic web: A never completely updated review
2006
This paper gives a never completely account of approaches that have been used for the research community for representing knowledge. After underlining the importance of a layered approach and the use of standards, it starts with early efforts used for artificial intelligence researchers. Then recent approaches, aimed mainly at the semantic web, are described. Coding examples from the literature are presented in both sections. Finally, the semantic web ontology creation process, as we envision it, is introduced.
OGC-to-W3C Services: A Wrapper-Based Solution for Geospatial Metadata Exchange
2018
When trying to compose services that are developed according to different standards, interoperability issues arise that are often faced by developing ad-hoc solutions. A typical example is represented by the composition of W3C and OGC services, which were developed more or less concurrently by independent organizations. In such a context, developing a wrapper that abstracts as much as possible the inner details and logic of a wrapped service well embraces the low-coupled nature of the general Service Oriented Computing paradigm. This paper focuses on the proper management of geospatial metadata into a W3C-based environment and is based on the development of a wrapper that exposes OGC functi…
A web search methodology for health consumers
2014
Nowadays, many people use the World Wide Web to seek medical and health information but different users, such as providers (e.g., physicians) and consumers (e.g., patients), have different needs and bring different levels of reading ability and prior knowledge. Generic and specific search engines and specialized health sites either do not exploit the whole web or overload users with information. This creates difficulties mainly to consumers who often do not exactly know how to find the desired information. Thus, an information retrieval system for the web that 'drives' the user in finding the relevant information would be very beneficial. This paper describes a web search methodology for he…
Monitoring Accessibility of Governmental Web Sites in Europe
2008
Web accessibility is an important goal of the European i2010 strategy. Several one-off surveys of eAccessibility have been conducted in the past few years. In this paper, we describe an approach to supplement the results of such surveys with automated assessments, that can easily be repeated at regular intervals. The software basis is provided by the European Internet Accessibility Observatory (EIAO). We analyse how the data collected by EIAO can be compared to other surveys.
Semantic to intelligent web era
2013
International audience; The Web has known a very fast evolution: going from the Web 1.0, known as Web of Documents where users are merely consumers of static information, to the more dynamic Web 2.0, known as social or collaborative Web where users produce and consume information simultaneously, and entering the more sophisticated Web 3.0, known as the Semantic Web by giving information a well-defined meaning so that it becomes more easily accessible by human users and automated processes. Fostering service intelligence and atomicity (the ability of autonomous services to interact automatically), remains one of the most upcoming challenges of the Semantic Web. This promotes the dawn of a ne…
Ontology-based Semantic Web Service platform in Mobile Environments
2006
The number of mobile terminals is continuously increasing in the world, although in many developed countries the market has saturated. Thus, the market can only grow if new service types are offered to the mobile terminals. One emerging technology that might make this possible is semantic web services. At the core of this technology are ontologies that are necessary for automatic discovery and composition of the services. In this paper we discuss how mobility affects the architectural considerations of semantic web service platform and particularly ontology management. We rely on reference architecture for Semantic Web Services in our work.
Semantic Multi-agent Architecture to Road Traffic Information Retrieval on the Web of Data
2013
In this paper, we describe a system based on FIPA standards to help the process of advertisement, discovery, invocation and reuse of traffic information on the web of data. The use of semantic web services (SWS) can be exploited to improve the outcomes in the discovery process, allowing end users to specify their need using concepts not keywords. Most of the traffic information is generally recovered by end users through web forms that specify their requirements, and must refill each time the same parameters to obtain the updated value from the web sites. Using agents besides Service Oriented Architecture (SOA), we will achieve interoperability between systems and also automatize the proces…
Natural Language Processing Agents and Document Clustering in Knowledge Management
2008
While HTML provides the Web with a standard format for information presentation, XML has been made a standard for information structuring on the Web. The mission of the Semantic Web now is to provide meaning to the Web. Apart from building on the existing Web technologies, we need other tools from other areas of science to do that. This chapter shows how natural language processing methods and technologies, together with ontologies and a neural algorithm, can be used to help in the task of adding meaning to the Web, thus making the Web a better platform for knowledge management in general.
