It seems to me, that utility function usually is just a set of facts. Is there a framework or model for utility function that can explain or predict utility function. I. e. if user has value for item A and B and there is item C (which is conceptually linked to items A and B, i.e. it has the color or A and usability features of B) then this framework can predict the user's value for item C?
Maybe there ir some kind of framework that can explain utility function? I.e. there are ontologies which have ABox component which is set of concepts and TBox component which set of instances of those concepts. Maybe there is framework that can list concepts that are linked to some products and each consumer have some value on those concepts and from this it is possible to derive the utility function for the actual products?
How utility function is used for modeling single customer profiles? Maybe utility function can be extracted from the Big Data that are associated with cash register data, contact calls and so on?
Is there some trend of research and practice along these lines? Maybe these are fairly common things and I don't know relevant keywords only?
