Abstract:
Information filtering is an important component in
warning systems. This paper proposes a two-level information
filtering model for generating warning information. In this
model, information is represented by n-tuple, whose elements are
values of information features. The features of information are
divided into critical and uncritical features. Within this model,
the collected information is filtered in two stages by users at
different levels. At the first stage, exceptions are separated from
normal information. And at the second stage, critical exceptions
are separated from uncritical information. To illustration the
proposed model, an example is discussed.
