    Intelligent Maps and Information Landscapes. Two New Approaches to Support Search and Retrieval of Environmental Information Objects
    (Environmental Communication in the Information Society - Proceedings of the 16th Conference, 2002) Tochtermann, Klaus; Sabol, Vedran; Kienreich, Wolfgang; Granitzer, Michael; Becker, Jutta
    In this paper, we present how two different knowledge retrieval techniques can be applied to improve search and retrieval for environmental information objects. Both approaches have in common that they provide users with as much guidance as possible. Our first approach capitalises on geographical metadata and intelligent maps as retrieval tool. The idea is to start a query with an intelligent map and to systematically narrow the scope of interest by choosing different query parameters. With our second approach we generate information landscapes, i.e. two-dimensional maps to display the results of search queries. In information landscapes documents with similar content are placed closer together, and islands appear where there is a concentration of closely related documents. The paper closes with a comparison of the two approaches and suggestion about when to use which approach.

    Web-based Support for Community Building of an European network of experts & professionals of ICT for environmental Sustainability
    (Integration of Environmental Information in Europe, 2010) Becker, Jutta; Maurer, Lisa; Tochtermann, Klaus
    In this paper, we have described our efforts to introduce a web based community platform to an existing community in the field of ICT for environmental sustainability. We argue that a given already established community solution can effectively foster collaboration between the experts and professionals. An interest group for ICT for environmental sustainability has been set up and existing community members have been invited to the online community. First guidelines and discussion forum structure have been introduced. The easy to use and already well known business community platform XING reflected a part of the whole community act ivies and network structure and can be used to foster further online community networking.
