| 中文摘要 | 在概念层次网络理论（Hierarchical Network of Concepts简称HNC）体系下，对句子语义分析时碰到的多动词难点，进行研究，并在句类分析系统中实现它。动词构成特征语义块，特征语义块是句子语义分析的中心，多动词处理就是句子语义中心确定的过程。研究方法是归纳和演绎并举。从具体实现中归纳出分析需要面对的各种现象，然后通过演绎方法，对各种现象给出处理策略。首先，在特征语义块构成原则的指导下，对动词进行分类，分为：1．需要附加动词的动词，充当EQ、Et，形成EQ+E的结构；2．需要附加体词的动词，形成E＋EH的结构；3．需要附加动词＋体词的动词，形成EQ＋E＋EH的结构：4．独立使用的动词。其次，利用v属性对特征语义块，按照其语义功能进行分类，形成Ep-Er、Eg-El、E1-E2的三种基本的E块配对，并对它们必须具备的条件和存在的难点进行分析研究。再次，具体设计实现了多动词分析的8个环节：1．提出了v属性的概念，对句类知识和词语知识进行高度抽象，总结出可以指导语义分析的22个v属性。2．利用v属性，分析特征语义块E的各种语义功能（Ep-Er、Eg-El、E1-E2）所必须的条件和出现的难点，这使得刘动词的分类和对E块语义功能的分类更贴近工程。3．给出了多动词处理的策略，并对假设检验作了详细的说明。4．提出了E作用域的概念，并对每种E（Ep-Er、Eg-El、El-E2）的作用域给出了定义，作用域可以在语义块内、语串、语串间。5．利用作用域的概念，总结了句子内部语串间的关系。6．设计实现了Eg-El上下并举的处理策略。7．设计实现了E感知规则，控制Eg的假设检验。8．设计实现了句类演绎规则，控制非Eg的假设检验。多动词处理，对汉语的理解处理尤为重要。述语动词的确定是汉语理解处理的重大课题，本文取得了关键性进展。本文也介绍了利用多动词处理技术，开发的一个涉及立场判断的应用系统，这个系统己经应用到一个商用产品中，并已经产品化。 |
| 英文摘要 | Under the framework of the theory of Hierarchical Network of Concepts (HNC), the research to deal with the difficulties arose by more verbs when the computer analyzes the semantic structure of the sentence, is presented here. The goal of this research is to make sure which verb is the center of the sentence. Also the strategy of analyzing these difficulties (HNC-MV) is designed in the Sentence Category Analysis system (SCA) by means of the hypothesis and test. The main work is: At first the verbs are classified to three classes, which are normal verb, the verb need attach other verb, and the verb need attach other noun. And the eigen chunk (we call it as E) is classified to three primitive partner which is Ep-Er, Eg-E/ and E1-E2 by means of the class of semantic attribute to verb. Here Eg is global E, and Ep and El are the other name of Eg. Er is the E in one sentence which is chunk extended into. E/ is local E in one chunk which is one sentence degenerated into. And then implemented these aspects: propose the class of semantic attribute for verb. These attributes are abstract of knowledge. propose the range controlled by E, and define the range of Eg, El, Er, E2. The E perceiving rule is done for Eg hypothesis and test; The Sentence Category Deduction Rule (SCDR) is implemented for the E hypothesis which is Er, E2, or El. HNC-MV is especially important for the Chinese NLP. HNC-MV have gotten some great improvement in the selection for the center of sentence, which is a most puzzle in Chinese NLP. This paper is also given a brief introduction of the Chinese Stand Determining System which is designed and developed based on HNC-MV. |
