由于是针对小文本的数据挖掘，本文研究的算法时间和空间复杂度都不高，因此有望成为一种实用、有效的信息检索技术。

Since aims at small texts data mining, its complexity of time and space is not high. So it can be said this algorithm will become one kind of practical and effective information retrieval technology.

可扩展标记语言(XML)不仅仅是一种标记语言，还是一种基于文本的数据存储格式，提供了应用和描述信息的树状结构的一种基于文本的方法。

Extensible markup language (XML), described as both a markup language and a text-based data storage format, offers a text-based means to apply and describe a tree-based structure to information.

The other big piece of available data we have is of course, the program text.

我们可以获得的另外一些数据就是,程序的文本，当你研究程序文本的时候。
