    Involving the Expert in the Delivery of Environmental Information from the Web
    (Proceedings of the 27th Conference on Environmental Informatics - Informatics for Environmental Protection, Sustainable Development and Risk Management, 2013) Wanner, Leo; Bosch, Harald; Vrochidis, Stefanos; Bouayad-Agha, Nadjet; Casamayor, Gerard; Johansson, Lasse; Karppinen, Ari; Moumtzidou, Anastasia; Kompatsiaris, Ioannis; Ertl, Thomas
    Automatic provision of accurate user need- and profile-tailored environmental information is of increasing demand. However, it is a challenging task with many facets. Among them is the difficulty to compile and cast into a formal representation all the expert knowledge needed to accurately and exhaustively acquire, assess and process the data in order to be able to reliably judge their relevance to the user and to produce an adequate summary and recommendations. Studies in Human-Computer Interaction show that both the satisfaction of the users with an application and the objective performance of a service increases if the users (in particular, experts) are assigned an active role in the system. Based on this insight, we propose a largely interactive environmental information acquisition and generation framework. The PESCaDO service involves the experts in four central tasks: (i) determination of criteria for the search of environmental nodes in the web; (ii) assessment of the relevance of the identified nodes; (iii) assessment of the quality of the data provided by the nodes, and (iv) selection of the content to be communicated to the user. Quantitative evaluations and user trials show that the performance of the system is good and the satisfaction with the service is high.

    Utilization of Semantic Annotations in Interactive User Interfaces for Large Documents
    (INFORMATIK 2008. Beherrschbare Systeme - dank Informatik. Band 2, 2008) Giereth, Mark; Wörner, Michael; Bosch, Harald; Baier, Patrick; Ertl, Thomas
    With new techniques, such as Microformats or RDFa, for integrating semantics into existing web formats, we expect a strong increase of semantically annotated documents in the web. This paper describes a new approach for utilizing seman- tic annotations to improve the user interface for large text documents by guiding the user’s attention to semantically annotated text sections using interactive focus+context techniques. We describe an implementation of the concepts in a patent information system.

    Das Web als personalisierte Entscheidungsplatform - Die PESCaDO Idee
    (INFORMATIK 2011 – Informatik schafft Communities, 2011) Bosch, Harald; Thom, Dennis; Ertl, Thomas
    Anwenderorientierte Datendienste im Web 2.0 wie Karten-, Wetter oder Verkehrsportale bieten ihren Nutzern in Alltagssituationen eine praktische Entscheidungshilfe. Dabei sind die Nutzer jedoch gezwungen diese Dienste selbst zu erschließen, auszuwerten und für ihr spezifisches Problem zu verknüpfen. Im PESCaDO- System sollen frei verfügbare Dienste mittels automatischer Extraktion als Grundlage für eine generische und integrierte Entscheidungsunterstützung im Kontext von Umweltdaten dienen. Den Nutzern werden dabei auf Basis eines intelligenten Anfrageeditors und einer semantischen Anfrageverarbeitung durch visuelle Repräsentationen relevante Informationen und Planungsvorschläge unterbreitet.
