    An Information Search and Filtering Engine for Sustainable Consumption Portal
    (Integration of Environmental Information in Europe, 2010) Lukács, Gergely; Cseh, Marcell
    In this paper, the key elements of a Web portal for sustainable consumption are introduced. The pieces of information – news, background articles, and advertisements – are ranked according to two criteria: Their potential to reduce the users’ ecological footprint and their costs. In order to be able to do this, the control engine of the Web portal uses three sources of information: (1) a personal profile prepared by the user with the help of a personal ecological footprint calculator, part of the portal; (2) an ontology on sustainable consumption; (3) a database on ecological footprint reduction measures, containing the potential of the measure as well as its costs. With the Web portal, a so called “integrated lifestyle package” of information and information services is built, providing the necessary width of coverage for widespread use.

    HIPPOLYTOS – Intuitive, übergreifende Recherche von Umwelt- und Geodaten mittels semantischen Technologien
    (Datenanforderungen und Informationsgewinnung zum Themenbereich Umwelt und Gesundheit, 2010) Lukács, Gergely; Kazakos, Wassilios
    Data on the environment and geographic data are often stored in databases as structured data. The thematic coverage and the number of useful analysis and visualisations are usually very broad and therefore challenging for the user. These challenges are also in the focus of the INSPIRE-directive and the SEIS-initiative. The platform disy Cadenza allows to query, analyze and visualize environmental and geographic data. Its approach -- especially the general functionality and the configurability – allows implementing large scale scenarios economically. In this contribution, a current development of the platform is presented, a so called “single-field-search” on the basis of semantic technologies. The drastically simplified view of the user as well as the architectur-extension is presented. The work is partially financed by the German Federal Ministry of Education and Research
