[求助]跪求stemming提取词根的程序！！！

[nijieqiong]

目前急需找一个stemming的现成程序，stemming是用来提取词根的，因为在英文中同一个词有各种不同的形式，要统一成一个概念，也就是用一个词根。希望各位大侠帮忙！

非常感谢，请问你发的第二个地址，是源代码吗？是什么语言的？我怎么一点也看不懂啊

The language is Snowball, see

http://www.snowball.tartarus.org/

Snowball is a small string-handling language, and its name was chosen as a tribute to SNOBOL (Farber 1964, Griswold 1968 ― see the references at the end of the introduction), with which it shares the concept of string patterns delivering signals that are used to control the flow of the program. See the Snowball manual on thais page.

You may also be interested in an English lemma list made in 1998 by Yasumasa Someya which "currently contains 40,569 words (tokens) in 14,762 lemma groups. It is still far from complete, but I hope you find the list useful in preparing your own more complete lemma list. If you have any questions or comments about this lemma list, feel free to contact me (ysomeya@gol.com)"

就是一个词表。然后在WordSmith settings中将这个词表load进去就可以了。
