APPARATUS AND METHOD FOR ANALYZING USER PREFERENCE ABOUT DOMAIN USING MULTI-DIMENSIONAL AND MULTI-LAYER CONTEXT STRUCTURE

摘要

PURPOSE: A device for analyzing user preference for a domain by using a multi dimensional and layered context structure and a method thereof are provided to supply a precise personalized service for a given domain by inferring a preferred domain element by considering a correlation between contexts for the domain. CONSTITUTION: A context structure generating unit(150) analyzes a record of a context to generate a context structure expressing a correlation between contexts. A context structure matching unit(160) matches a current context with the context structure to calculate a context matching value. A context collecting unit(130) collects the current context to store the same in a context storage unit. The context structure is generated in each element of the domain. A domain preference query unit(110) requests a preference value for the element to a control unit(120) according to a request of an application.
