Integration and interoperability is a basic requirement for geographic
information systems (GIS). The web provides access to geographic data in several
ways: on the one hand, web-based interactive GIS applications provide maps and routing
information to end users; on the other hand, the data of some GIS can be accessed
in a programmatic way using a web service. Thereby, the data is made available for
other GIS applications. However, integrating data from various sources is a tedious
task which requires the mapping of the involved schemas as a first step. Schema
matching analyzes and identifies similarities of two schemas, but all approaches
can be only semi-automatic as human intervention is required to verify the result
of a schema matching algorithm. In this paper, we present an approach that improves
the matching result of existing solutions by using semantic information provided
by the context of the geographic application. This reduces the effort for manually
correcting the results which has been validated in several application examples.

| Kurzfassung: |
In communities of sportspeople social interrelations play a very important role.
They are motivation for increasing sportive performances and furthermore build the
coherence of like-minded groups. In this position paper we describe how sportspeople
performing outdoor activities can be supported with high-tech location aware software
on mobile devices. Fine grained location information is used to measure sportive
performance and share it throughout the community. Location based services can
help to connect people sharing similar interests and initiate new communication
cannels based on their common sportive preferences.

| Kurzfassung: |
This paper reports on the architectural development process implemented
in the MICA (Multimodal Interaction in Context-Adaptive systems) project.
The goal is to make a major step towards natural human interaction with
multimodal systems and the provision of pro-active assistance: we aim to
do this by combining explicit and implicit interaction on different modalities
reflected in a new layer based architecture for multimodal interaction.
The client application was developed with .NET Framework 2.0 which
allowed a rich graphical user interface so we could easily support for
proactivity (highlight certain areas on the screen depending on the
current context of the user) and multi-modality (output of
informations using context-dependant channels e.g. audio or text).
