最优秀的语言设计需要语法分析器自身具有更少的规则,从而变得更加透明;同时,尽快把生成的表达式在接口处进行拼读,以便减少工作记忆负担。然而,OT语法框架中语法分析器的非透明特征与整体性推导与上述学界的流行观点相悖。因而,本文认为,虽然它具有较强的解释力,但是并不代表这种理论具有可学性。 The finest language design requires the parser itself to have fewer rules to make it more transparent; at the same time, the resulting expressions are spelled out at the interface as soon as possible to reduce the working memory burden. However, the non-transparent features and parsimony of grammatical parsers in the OT grammar framework run counter to the popular viewpoints of the above academic circles. Therefore, this article argues that although it has a strong explanatory power, it does not mean that such a theory is understandable.
