Analysis and Processing on the Composing of Noun Conglomeration Combination

Analysis and Processing on the Composing of Noun Conglomeration Combination ① Liang Xiong & Quan Zhang (Institute of Acoustics, Chinese Academy of Sciences, Beijing 100080, China) Email :bright84@sina.com Abstract：The position of noun is replaced by numerous concept types under the system of HNC Theory. Noun is called as a general designation describing objective entity, including type of g、z、r in abstract concepts and p、w、x in concrete concepts. Computers have difficulties in recognizing the relationship of preferential combination in Noun Conglomeration. The paper describes the combination of nouns in different concept types, according as the rule of decreasing differentiation. The rule of concept differentiation sequence among concrete concepts can be summarized as the following: firstly aggregate person concept, secondly individual person concept, thirdly physical concept, the last one is physical property concept. The differentiation degree of physical concept depends on the differentiation degree of semantic network that they hang over.

The position of noun is replaced by numerous concept types under the system of HNC Theory. Noun is called as a general designation describing objective entity, including type of g、z、r in abstract concept and p、w、x in concrete concept. The definition of noun conglomeration is defined as two or more nouns in succession in a sentence. The Coordinate Combination and Modificatory Combination have obvious language marks, but Noun Conglomeration Combination does not have symbolic mark. Computers have difficulties in recognizing the relationship of preferential combination in Noun Conglomeration. The following will describe the combination of nouns in different concept types, according as the rule of decreasing differentiation. Abstract concepts have their own semantic networks. On the contrary, concrete concepts have to hang over the abstract concepts except a few concept types having their own semantic networks. 2 Between the types of concrete concepts It is easy to grasp the classification of concrete concept， so the classification of concrete concepts under the system of HNC Theory is exhaustive. HNC divides the concrete concepts into three main bigger types, such as person concept(p), physical concept(w) and physical property concept(x). Then each type is divided into several smaller subclasses. The concrete concept has not especial semantic network except two types——fundamental physical concept(jw) and fundamental physical property concept(jx). For the sake of describing concrete concept, we use the semantic network of abstract concept by the way of hanging over it. This paper believes it necessary to separate the aggregate person concept from the person concept. As a result, there are four main types in total at last. These four types are just four levels of the degree of concept differentiation. The degree of concept differentiation from upper to the bottom is a gradually decreasing sequence. The degree of concept differentiation inside every level is equal to each other. First class: The concept of aggregate person, including pe, p- and so so. Second class: The concept of individual person, including p, pr,rp,pg …
