Positive and Negative Dependence for Evidential Database Enrichment

چکیده
Uncertain databases are used in some fields to store both certain and uncertain data. When uncertainty is represented with the theory of belief functions, uncertain databases are assumed to be evidential. In this paper, we suggest a new method to quantify the source degree of dependence in order to enrich its evidential database by adding this dependence information. Enriching evidential databases with its sources degree of dependence can help user when making his decision. We used some generated mass functions to test the proposed method.
