INSIGMA stands for Intelligent System for Global Monitoring Detection and
Identification of Threats. The main objective of the project is to develop a complex
monitoring system that will allow to identify objects in the monitored environment
and, based on the stored information and advanced algorithms, identify threats
related to both the traffic and suspicious behaviour of people. The system can be
also used for traffic management and route planning for individual users and for
the public safety services. The route planning will take into account also dynamic
complex parameters that provide the possibility to select the route in special circumstances,
e.g. after a road accident or a natural disaster, in difficult weather
conditions, etc.
One of the major novelties of the INSIGMA project is application of ontologies.
They are used to describe all the elements of the system, model entities
describing logical and physical elements, data collected by sensors, as well as dependencies
among them. This all is to support efficiency of information retrieval
in such a complex information system. However provision of a set of well-formed
ontologies has additional advantage. It allows to deliver knowledge on the basis
of the reasoning process that bases on information that are flowing from the monitoring
subsystem. That is why in the INSIGMA project there has been also defined
run-time ontology used for automatic identification of threats and dangers related
to the traffic and, in case of emergency, for automatic generation of the notification
to public safety services (like police, ambulance services, fire brigade) – so called
INSIGMA Event Ontology (IEO).
The remainder of this paper is as follows: in section 2 we describe motivation
for our work, in section 3 – ENS that is the implementation of the run-time
ontology application engine, in section 4 – the INSIGMA event ontology itself, in
section 5 presents the RM that infers knowledge from the information collected.
Section 6 presents results of testing the reasoning module. In section 7 we identified
further work in the area of run-time ontologies that we are planning to perform
in the INSIGMA project. The article is finalised by the summary and conclusions.
II. Motivation
INSIGMA project will be finished with the development of the prototype
system. Currently the system is being developed component by component. One
of the most important services that INSIGMA will provide is ENS. It enables creation,
delivery and processing of short formalised messages about events of certain type.
Information about events will be stored in Events Repository (ER) and made available
to the other functional modules of the INSIGMA system [3].
ENS consists of two elements – reporting module located at the client device
and notification module (including the reasoning module) located at the server
side. The reporting module was proposed as a complementary to the fixed road
traffic monitoring infrastructure composed of intelligent video cameras and sen-
