There is a set of attributes that customise the interface associated to a
particular fact. The attributes are:
- This is an attribute that associates a long name, i.e. a string, to
the fact. Experts use atomic short mnemonic names to identify a fact
simplify rules and meta-rules writing. The long name is the representation
of the fact to be shown to users to help them understand the concept
the fact represents.
- The value of this attribute is a string that the system uses
to query a user about the value of the fact.
- When the system asks the user for the value of a fact, the
user can ask for help. In that case the
explanation attribute value, a string, is presented to the user.
- It is the name of a file containing an image to be shown
together with the question when that fact is asked to the user. For instance in
Spong-IA application, when the system asks about the external
aspect of the sponge the user wants to classify, an image containing
pictures representing the possible forms is shown to him.
