摘要：It is observed that the context of arguments sometimes deviates in debates and disputes. The subjects and predicates used in cross debates are similar but different between two opposing arguments. In this paper, we deal with debates and propose a fundamental procedure for examining the context of arguments. The procedure consists of two practical processes; one extracts constructive arguments and refutations (or replies), and the other examines the context between them. The procedure of examining the context is executed by the verification of words in the propositions of constructive arguments and refutations. The context between the propositions in which the verified words do not agree with each other is considered to be broken, and the proposition for the context is judged to be invalid.
