Abstract: The paper presents a proposal for a framework for the identification, assessment and selection of open data sources based on certain quality criteria, such as accessibility, relevance, accuracy & reliability, clarity, timeliness & punctuality, and coherence & comparability. The framework concerns mainly open data sources and focuses on their quality. The open data are used to enhance existing internal data and to fuse them with data from other sources. The framework consists of few steps starting from definition of quality criteria based on review of relevant literature and user requirements, then identification of potential sources, sources assessment and selection, and finally data retrieval process. For each step, a specific approach is described, how it may be conducted in practice. The proposed framework is evaluated using a real use case scenario from the maritime domain. The main approach utilized in this use-case is the Delphi method with some characteristics of Analytic Hierarchy Process. Collapse

Abstract: The paper presents research on the development of an ontology-based evaluation tool for the assessment of the utility of natural disaster management (NDM) websites and potential standards and guidelines for their development and evaluation. It analyzes ratings and feedback on the development of the ontology for NDM website elements from stakeholders including experts managing NDM websites and potential users of the websites and evaluates such ratings using relative and absolute utility theory. It suggests evidence that NDM websites show a lack of readiness. Collapse

Abstract: Recent natural disasters have brought forth the need for disaster preparedness, planning, and management. Hurricane Katrina demonstrated the usefulness of websites in dealing with a natural disaster. However, little is known about the necessary contents and structures of web-based information management for natural disaster preparation. In this paper, we focus on developing the ontology structure of elements for web-based disaster management systems. We provide a comprehensive review of the existing semi-structured data representation technologies and select the appropriate set for developing and representing the ontology structure. Web elements are identified based on the grounded theory approach using an inventory of 100 non-profit disaster websites and their numerous webpages. The selected technologies are used to organize the ontology structure and the results are coded into a web-based system tool (WB-OS) that makes the ontology structure accessible on the web. Such ontology structure of web elements is utilized to evaluate the quality and completeness of current websites Collapse
