Query Condition of Chinese Query Statement in Database

通过对汉语查询句的研究,建立了复合概念、逻辑概念与标准概念的内在联系.通过分析各种查询条件,得出查询条件表达式可以形式化表示为二叉树的结论,在此基础上,构造了查询条件字符块转换为二叉树的一套算法.

Through the study of the Chinese query statement, the internal relationship of compound conceptions ,logical conceptions and standard conceptions is formed and studied. By analyzing all kinds of query conditions of the Chinese query statements, an important conclusion that query conditions expressions can be expressed as the binary tree is drawn. A set of algorithms changing character block of the query condition into the binary tree is constructed.
