Zusammenfassung: | Conditional ceteris paribus preference networks (CP-nets) are commonly used
to capture qualitative conditional preferences. In many use cases, when the
preferential structure of an agent is incomplete, information from other
preferential structures (e.g. that of other users) preferences can be used to
fill in the gaps. Earlier works proposed methods to symmetrically merge
multiple incomplete CP-nets by means of voting semantics. However, the merged
CP-net can contain preference relations that do not fit to a given user's
original preference profile. This paper proposes an asymmetric merging (or
enriching) method to obtain and fill-in preference relations of a user's CP-net
from another CP-net in a way that preserves the original preference relations. |
