A framework for personal content search and recommendation based on personal experiences

Recently, the number of personal content objects which a person has to manage is increasing rapidly. In this paper, we propose the Experience-Web (X-Web), which is a data model for managing various types of personal content objects in a unified manner based on their contexts. The X-Web consists of three kinds of modelling units: content, experience, and person, and contexts of a personal content object are expressed as experiences. Units are classified into containers, and a ranking function is defined between two containers. Combinations of ranking functions can represent various requirements for searching and recommending personal content objects.
