数据库自然语言查询界面

数据库技术的普及使得用户对数据库应用界面的要求越来越高，以往的几类接口都需要用户有较高计算机知识水平，而且必须经过一定的培训，这样就会造成人力物力的浪费而且不利于计算机的普及。本文探讨的是一种更为方便简洁不秀学习即可操作的自然语言界面。

A CHINESE LANGUAGE INTERFACE OF DATABASE

The interface is a key part of database . The interfaces developed before are not suitable for people who have no computer background to use .We have developed one Chinese interface of database . It is very easy to use and very powerful . The natural language understanding method presented here is different from that of semantic or syntax . We proposed that the natural language understanding under specifically pragmatic environment strongly connected with the environment and goal . From this , the characteristics of Chinese language used in database inquiring have been analyzed , and the model depending on data retrieving conditions has been set up . Upon this model , a practical system of Chinese interface for database(CISD) has been developed with the algorithm of selecting relative information and matching relative Chinese characters .
