Abstract

A Logic of Multiple-valued Argumentation LMA was formalized by Takahashi and Sawamura (LMA) on an expressive knowledge representation language, Extended Annotated Logic Programming (EALP). LMA allows agents to construct arguments under uncertain knowledge and to argue with other agents on uncertain issues in the open networked heterogeneous environment. In this paper, we describe an implementation of LMA (called AASLMA) in which agent communication is realized in C and symbolic argument construction in Prolog. The interface design proper to argumentation is also taken into account in the implementation. This is helpful for us to understand argument processes and results. The versatility of LMA is shown through the implementation and some convincing argument examples that employ various types of multiple-valuedness.
