Failure analysis expands into forensics engineering for it aims not only to identify individual and symptomatic reasons of failure but to assess and understand repetitive failure patterns, which could be related to underlying material faults, design mistakes or maintenance omissions. NAVMAT approach utilizes a focused common-cause failure methodology for the naval and marine environment, to begin with. It will eventually support decision making through appropriate Artificial Intelligence and Natural Language Processing methods. The presented work describes the design of a knowledge based system dedicated to effective recording, efficient indexing, easy and accurate retrieval of information, history of maintenance and secure operation concerning failure incidents of marine materials, components and systems in a fleet organisatio...

This tool enables the annotation of Web pages from different domains and for different information extraction tasks providing a user-friendly interface to human annotators. Annotated information is stored in a representation format that can easily be exploited.

The project aims to develop technology for extracting interesting information from domain-specific web pages. It is therefore important for CROSSMARC to identify web sites in which interesting domain specific pages reside (focused web crawling). This is the role of the CROSSMARC web crawler.

Various “trust marks” and filtering portals have been created in order to assist consumers in retrieving quality medical information. Consumers are using search engines as the main tool to get health information; however, the major problem is that the meaning of the web content is not machine-readable in the sense that computers cannot understand words and sentences as humans can. In addition, trust marks are invisible to search engines, thus limiting their usefulness in practice. During the last five years there have been different attempts to use Semantic Web tools to label health-related web resources to help internet users identify trustworthy resources. This paper discusses how Semantic Web technologies can be applied in practice to generate machine-readable labels and display their content, as well as to empower end-users by providing them with the infras...

The ever increasing amount of freely available healthcare-related information generates, on the one hand, excellent conditions for self-education of patients as well as physicians, but on the other hand entails substantial risks if such information is trusted irrespective of low competence or even bad intentions of its authors. This is why medical website

M-PIRO is developing technology that allows personalized multilingual object descriptions, in both textual and spoken form, to be produced from symbolic information in a database and small fragments of text. The technology is being tested in the context of electronic museums, where a prototype that produces dynamically multilingual exhibit descriptions for presentations over the web has already been developed. This paper focuses on M-PIRO’s authoring subsystem, which allows domain experts with no language technology expertise to configure the system for new applications. The authoring facilities allow the experts to define or modify the structure of the underlying database, its contents, and the system’s domain-dependent linguistic resources. Previews of the generated texts can also be produced during the authoring process to monitor the content and quality of the resulting descriptions. 1

However manually labelling health resources is a tedious task. Based upon state-of-the-art technology in the areas of semantic web, content analysis and labelling, the MedIEQ project integrates existing technologies and tests them in a novel application: AQUA, a system aiming to automate parts of the labelling process in health-related web content. AQUA provides tools that enable the creation of machine readable labels, tools that crawl the web to locate unlabelled health web resources, suggest labels for them according to predefined labelling criteria and monitor them. This paper describes the current status in the area of health information labelling and explains step-by-step how AQUA paves the way towards the automation of the labelling process.

The paper presents the QUATRO processes for label validation and user notification, and outlines the architecture of QUATRO system.

Organizations around the world are working on establishing standards of quality in the accreditation of health-related web content. For the full success of these initiatives, they must be equipped with technologies that enable the automation of the rating process and allow the continuous monitoring of labeled web sites alerting the labeling agency. In this paper we describe the European project MedIEQ that integrates the efforts of relevant organizations on medical quality labelling, multilingual information retrieval and extraction and semantic resources, from six different European countries (Spain, Germany, Greece, Finland, Czech Republic and Switzerland). The main objectives of MedIEQ are: first, to develop a scheme for the quality labelling of medical web content and provide the tools supporting the creation, maintenance and access of labelling data according to this scheme and second, to specify a methodology for the content analysis of medical web sites according to the MedIEQ scheme and develop the tools that will implement it.

The paper describes the existing labelling mechanisms, presents the main objectives of the EC-fundet project MedIEQ, and the tools that will be implemented, and discusses the results from an initial survey on the Greek medical web using some of the project tools.

The ever increasing amount of freely available healthcare-related information generates, on the one hand, excellent conditions for self-education of patients as well as physicians, but on the other hand entails substantial risks if such information is trusted irrespective of low competence or even bad intentions of its authors. This is why medical website certification (also called 'quality labeling') by renowned authorities is of high importance. In this respect, it recently became obvious that the labeling process could benefit from employment of web mining and information extraction techniques, in combination with flexible methods of web-based information management developed within the semantic web initiative. Achieving such synergy is the central issue in the MedIEQ project. The AQUA (Assisting QUality Assessment) system, developed within the MedIEQ project, aims to provide the infrastructure and the means to organize and support various aspects of the daily work of labeling experts.
