Abstract:

Time is an important element of describing the process of argument and the changes of argument activities, and it is active to introduce time into argumentation framework. This paper proposes a temporal extended value based argumentation framework (TEVAF) based on Dung’s standard argumentation framework (AF) and BenchCapon’s value based argumentation framework (VAF). First, we analyze their limitations in describing temporal and values which are related to arguments. Then,according to the requirements, TEVAF is proposed.We present a complete description of the structure of framework,and the  semantics of the framework,and give the fundamental Lemma and some basic results shown by Dung’ argumentation framework,which also hold for TEVAF.

Key words: temporal, argument, argumentation framework
