摘要：语法分析器的设计落后于语言学理论。虽然现代转换语法在很大程度上抛弃了复杂的、特定于语言的规则系统，转而支持原则和参数的模块化子系统，但支撑现有自然语言解析器的规则系统仍然庞大、详细和复杂。语言学向模块化理论的转变是因为这种规则体系在科学上的缺陷。这些科学上的弊病转化为工程上的弊病，使构建自然语言系统变得困难。这些问题的解决方法在解析器设计中应该与在语言理论中相同。向句法模块化理论的转变应该在句法分析实践中重复。解析器应该将其操作建立在原则和参数的交互模块上，而不是复杂的、单一的规则系统。如果它能够成功实现，这种转变将使构建自然语言系统变得更容易，因为它将缩短和简化解析所需的语言描述。它还将允许解析器设计跟踪语言理论的新发展。(作者)
Abstract : Parser design lags behind linguistic theory. While modern transformational grammar has largely abandoned complex, language-specific rule systems in favor of modular subsystems of principles and parameters, the rule systems that underlie existing natural-language parsers are still large, detailed and complicated. The shift to modular theories in linguistics took place because of the scientific disadvantages of such rule systems. Those scientific ills translate into engineering maladies that make building natural-language systems difficult. The cure for these problems should be the same in parser design as it was in linguistic theory. The shift to modular theories of syntax should be replicated in parsing practive. parser should based its actions on interacting modules of principles and parameters rather than a complex, monolithic rule system. If it can be successfully carried out, the shift will make it easier to build natural-language systems because it will shorten and simplify the language descriptions that are needed for parsing. It will also allow parser design to track new developments in linguistic theory. (Author)
