Argumentation Databases

We introduce a proposal to give argumentation capacity to databases. A database is said to have argumentation capacity if it can extract from the information available to it a set of interacting arguments for and against claims and to determine the overall status of some information given all the interactions among all the arguments. We represent conflicts among arguments using a construct called a contestation, which permits us to represent various degrees of conflicts among statements. Argumentation databases as proposed here give exactly the same answers to queries as a database without argumentation capacity, but which are annotated with confidence values reflecting the degree of confidence one should have in the answer, where the degree of confidence is determined by the overall effect of all the interactions among the arguments.
