The increasing availability of sensor data through a variety of sensor-driven devices
raises the need to exploit the data observed by sensors with the help of formally
specified knowledge representations, such as the ones provided by the Semantic Web.
In order to facilitate such a Semantic Sensor Web, the challenge is to bridge between
symbolic knowledge representations and the measured data collected by sensors. In
particular, one needs to map a given set of arbitrary sensor data to a particular
set of symbolic knowledge representations, e.g. ontology instances. This task is particularly
challenging due to the potential infinite variety of possible sensor measurements.
Conceptual Spaces (CS) provide a means to represent knowledge in geometrical vector
spaces in order to enable computation of similarities between knowledge entities by
means of distance metrics. We propose an ontology for CS which allows to refine symbolic
concepts as CS and to ground instances to so-called prototypical members described
by vectors. By computing similarities in terms of spatial distances between a given
set of sensor measurements and a finite set of prototypical members, the most similar
instance can be identified. In that, we provide a means to bridge between the real-world
as observed by sensors and symbolic representations. We also propose an initial implementation
utilizing our approach for measurement-based Semantic Web Service discovery. |
