NLML --一种描述无限英语语法的置标语言
NLML--a Markup Language to Describe the Unlimited English Grammar
摘要：
在本文中，我们提出了NLML（自然语言置标语言），一个置标语言来描述任何语法正确的英语表达的句法和语义结构。首先分析了相关工作，论证了NLML的必要性：形式简单，易于管理，直接存储。然后从句子（不同复杂度、语态、语气、时态）、从句（关系从句和名词从句）和短语（名词短语、动词短语、介词短语、形容词短语、副词短语和谓语短语）三个层次详细介绍了NLML对英语语法的描述。最后以两个典型的例子：NLOJM（Java中的自然语言对象模型）和NLDB（自然语言数据库）说明了NLML在自然语言处理中的应用领域。
英文摘要：
In this paper we present NLML (Natural Language Markup Language), a markup language to describe the syntactic and semantic structure of any grammatically correct English expression. At first the related works are analyzed to demonstrate the necessity of the NLML: simple form, easy management and direct storage. Then the description of the English grammar with NLML is introduced in details in three levels: sentences (with different complexities, voices, moods, and tenses), clause (relative clause and noun clause) and phrase (noun phrase, verb phrase, prepositional phrase, adjective phrase, adverb phrase and predicate phrase). At last the application fields of the NLML in NLP are shown with two typical examples: NLOJM (Natural Language Object Modal in Java) and NLDB (Natural Language Database).
