1 Value "null" is related to the fact that no signal is received from sensors detecting movement. 2 Parameter "P" represents data reliability, and it is computed by the algorithms used for feature extraction.
and sound of the object, state of the object and any other property that the object can detect using specific sensors such as waterflows (see Table 4).

The expressive power of ASP is used in the context interpretation phase in order to disambiguate unclear situations as much as possible by using defaults, nondeterministic choice and constraints over the solutions (see Section 4.1 for details).

As an example, if you consider the problem of tracking the person on the grid, the
