N2 - This works presents a method for explicit acquisition of
context-dependent user preferences (preferences which change depending on a
user situation, e.g., higher interest in outdoor activities if it is sunny
than if it is raining) for Smart Home - intelligent environment, which
recognizes contexts of its inhabitants (such as presence of people,
activities, events, weather etc) via home and mobile devices and provides
personalized proactive support to the users. Since a set of personally
important situations, which affect user preferences, is user-dependent, and
since many situations can be described only in fuzzy terms, we provide users
with an easy way to develop personal context ontology and to map it fuzzily
into common ontology via GUI. Backward mapping, by estimating the probability
of occurrence of a user-defined situation, allows retrieval of preferences
from all components of the user model (7 refs.)
