摘要：Conditional Preference Networks (CP-nets) are a
compact and natural model to represent conditional qualitative
preferences. In CP-nets, the set of variables is fixed in advance.
That is, the set of alternatives available during the decision
process are always the same no matter how long the process is. In
many configuration and interactive problems, it is expected that
some variables are subject to be included or excluded during the
configuration process due to users showing interest or boredom
on some aspects of the problem. Representing and reasoning with
such changes is important to the success of the application and
therefore, it is important to have a model capable of dynamically
including or excluding variables. In this work, we introduce active
CP-nets (aCP-nets) as an extension of CP-nets where variable
participation is governed by a set of activation requirements.
In particular, we introduce an activation status to the CP-net
variables and analyze two possible semantics of aCP-nets along
with their consistency requirements.
