Recognition Structure of Uncertainty: a Unified Framework for Representation, Reasoning and Learning

In this paper a unified framework for representing, reasoning and learning of uncertain information is put forward. The 4-valued recognition structure is used to measure the uncertain degree of uncertain information and thus more powerful expressive capacity is attained. Moreover, the framework supports the efficient acquisition of the uncertain information. These features make the framework more practical than existing theories of reasoning about uncertainty.
