   abstract = {In these days, enterprises are more and more confronted to fast changing and
      turbulent markets. In order to remain competitive, they have to quickly adapt
      themselves to these new situations. The integration solutions employed in such
      an environment enable the required agility, by using a loose and flexible
      integration architecture. We propose an integration solution based on the
      concept of propagating data changes from one information system to the affected
      information systems. This paper focuses on the question: how data from other
      data services can be accessed and exploited to enhance a data change
      propagation system. These services are based on a service-oriented architecture
      (SOA) using XML technologies (e.g. SOAP). We developed the Data Service
      Description Language (DSDL) to define the data structures of the data service.
      This description is used to create the above mentioned Transformation Scripts
      as well as to generate requests for accessing remote data. A layered system
      approach is introduced to facilitate both the architecture and its
      implementation.},

   abstract = {The development of successful new products and services in highly dynamic
      business environments has become an extremely difficult task. Innovation
      managers have to utilize a considerable amount of enterprise-internal and
      enterprise-external information to judge the potential of new products,
      services and technologies.
      
      Scenario management is a powerful instrument to face this problem. Scenarios
      represent an intuitive concept to comprehend complex present-day and future
      situations. The scenario technique is a method for building such scenarios.
      Assessments of future business environments relying on structured scenarios
      enable innovation managers to target lucrative market segments and to select
      promising product ideas. However, diverse enterprise-internal and
      enterprise-external resources have to be utilized to assist the scenario
      development process. Last but not least, existing methods are often extremely
      time-consuming and existing tools for scenario development fail to provide a
      comprehensive solution as they are limited to certain steps in fixed workflows.
      
      In this paper, we propose a modular web-based framework for the flexible and
      efficient development and handling of scenarios. Key aspects of our framework
      are module-based enterprise-specific workflows, the integration of distributed
      human resources into the scenario development process and diverse interfaces to
      enterprise-internal and enterprise-external information sources. The framework
      is based on self-contained software modules that cover important steps of the
      scenario management process. This modularity allows the easy supplementation of
      existing 'scenario technique' methods with newly developed methods that are
      incorporated into modules and can be combined in a flexible way to fit
      enterprise-specific requirements.},

   abstract = {Information provided by a shared dynamic context model offers new possibilities
      in the realm of autonomous robots. The availability of external context
      information can be used by a robot to extend and to validate the locally
      acquired knowledge about its dynamic environment. A lot of helpful context
      information is already available in digital form and its quantity will increase
      rapidly, according to the vision of ubiquitous computing.
      
      In this paper we present the Nexus Platform capable of managing a global
      dynamic context model that can be addressed and accessed in an easy and uniform
      way by all kinds of context-aware applications (like robots). Advantages for an
      autonomous wheelchair robot using the Nexus Platform are depicted within an
      airport scenario. We further present a framework for a sensor fusion agent,
      able to perform multi-sensor data fusion with selective attention control,
      concerning the current situation of the environment.},

      applications and users additional information on the data’s origin, its

      context models: it can be used for resource finding, enhanced data selection,
      trust and data quality issues and sensor fusion. We show how meta data included
      into an object-based context model influences the data modeling and the
      selection process in the query language. Finally, we describe our
      implementation of the presented functionality in the Nexus platform.},

   abstract = {In this paper, we address the data management aspect of large-scale pervasive
      computing systems. We aim at building an infrastructure that simultaneously
      supports many kinds of context-aware applications, ranging from room level up
      to nation level. This allembracing approach gives rise to synergetic benefits
      like data reuse and sensor sharing. We identify major classes of context data
      and detail on their characteristics relevant for efficiently managing large
      amounts of it. Based on that, we argue that for large-scale systems it is
      beneficial to have special-purpose servers that are optimized for managing a
      certain class of context data. In the Nexus project we have implemented five
      servers for different classes of context data and a very flexible federation
      middleware integrating all these servers. For each of them, we highlight in
      which way the requirements of the targeted class of data are tackled and
      discuss our experiences.},

      Typically, this data is exspecially gathered and preprocessed in a particular
      way (e.g. in a spatial data base). Up to now most of these applications ignore
      an existing large information space, the World Wide Web. Web pages can be
      mapped to locations and then accessed by location-aware applications with
      spatial predicates. We want to automate the process of mapping web pages to
      locations because of the huge amount of data available in the WWW. Our web
      robot DCbot analyses web pages using pre-defined rules and spatial knowledge
      and maps them to locations. In the demonstration we will show some location
      mapping results of DCbot and, in addition, we will let DCbot scan locally
      stored web pages at demonstration time, so that effects of changes of the
      content can be shown.},
