<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>In a project we are trying to explicitly stick to the SRK
framework of Rasmussen in the implementation of a cognitive model. Rules and
knowledge are going to be implemented at first. The associative layer will use
signs (e.g. bread) while the cognitive layer will use symbols (e.g. food). Both
symbols and signs are stored in the memory. Now we think of implementing a
translator, which is conceptually part of the memory, that translates signs to
symbols and vice versa. The signs and symbols will probably be represented in a
semantic network.<o:p></o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'><o:p> </o:p></span></font></p>
<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>Furthermore, we have the idea of activating goals in the
memory depending on new symbols and sending the activated goals to the
cognitive layer that can reason about which goal to choose based on for
instance priorities. When in a goal hierarchy a procedure is reached the
cognitive layer passes the goal to the associative layer, which then tries to
reach the goal. If information is missing to succeed in the goal the
associative layer asks the cognitive layer for this information. For example:
the cognitive layer has passed the goal “land the plane” to the
associative layer, but the information about </span></font><font size=2
face=Verdana><span style='font-size:10.0pt;font-family:Verdana'>where to land </span></font><font
size=2 face=Arial><span style='font-size:10.0pt;font-family:Arial'>is not
unambiguously present in the memory, so it asks the cognitive layer to get the
“where” information. The cognitive layer than asks the memory for a
list with signs (Rome, Zurich, Washington) of landing spots (symbol) and
reasons about the best spot according to some specifications and current context.
The best spot is given back to the associative layer that can complete its goal
to land.<o:p></o:p></span></font></p>

<p class=MsoNormal><font size=2 face=Arial><span style='font-size:10.0pt;
font-family:Arial'>We are very interested in your ideas on this, the cognitive
plausibility and perhaps literature and example programs that describe similar
implementations to crystallize our ideas further.</span></font><font size=2
