    This work introduces an approach to discover collaboration partners and adequate advising experts in a workplace-embedded collaborative e-learning environment. Based on existing papers dealing with work task and user context modelling, we propose the following steps towards a successful collaboration initiation. In the beginning, the user's current process task needs to be identified (1). Taking into account the knowledge about the current process, availability of experts as well as organizational and social distance, relevant experts regarding the actual work task of the learner are pre-selected by the environment (2). Depending on the pre-selection and users' preferences, the potential collaboration partners are displayed in an expert list (3). That way, the learner is able to initiate beneficial collaborations, whose transcripts are used to enhance the existing knowledge base of learning documents (4).

    In this paper we introduce the concept of context-aware services as an extended form of locationbased services. We describe a new architecture for realizing context-aware services which has a number of key benefits. This architecture relays on mobile software agents as security-centric middleware. Our approach allows to combine disjunct databases by establishing applicationdependant links between remote data sets with a proprietary access. We describe all necessary roles and places to establish a multilateral security concept for all participants.

    Disaster response and recovery efforts require timely interaction and coordination of public emergency services in order to save lives and property. Today, IT is used in this field only to a limited extent, but there is a tremendous potential for increasing efficiency and effectiveness in coping with a disaster. In this paper we sketch requirements and innovative technology for an integrated disaster management communication and information system, addressing in particular network, configuration, scheduling and data management issues during the response and recovery phases.

    Verschiedene elektronische Informationsquellen bieten ihre Dokumente in unterschiedlicher Form an. Insbesondere ihre Struktur ist oft nur in anbieterspezifischem Format verfügbar. Für die weitere Bearbeitung, den Austausch und die Archivierung muß diese Struktur extrahiert werden. Diese Dissertation entwickelt einen Ansatz zur automatischen Erkennung der Struktur von elektronischen Dokumenten auf Basis von nur wenigen, manuell strukturierten Beispielsdokumenten. Dazu wird eine regelorientierte Sprache zur Spezifikation von Erkennungsprogrammen eingeführt. Auf dieser Basis werden Techniken des maschinellen Lernens - Versionsraum und Grammatik-Inferenz - entwickelt, die Erkennungsprogramme aus Beispielen generieren.
