| Abstract: | 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. |
