[FONT=宋体]有一批词块，欲生成它们的块首词词表（如[/FONT]I WAS SORT OF[FONT=宋体]的块首词是[/FONT]I[FONT=宋体]，[/FONT]RM I DON'T KNOW[FONT=宋体]的块首词是[/FONT]ERM，词表见下文）。
本论坛上有好心C友（如liubing1986snowy， seanxpq ）建议我用powergrep[FONT=宋体]批量提取、[FONT=宋体]用正则表达式（如^(\S+)\s， ^(\w+)\s）提取。[/FONT][/FONT]
[FONT=宋体][FONT=宋体]已下载Powergrep试用版，只是不懂如何操作。没使用过该软件嘛，真是摸不着北！[/FONT][/FONT]
[FONT=宋体][FONT=宋体]可以指点指点吗？万分感谢！[/FONT][/FONT]
