一、
电子邮件抄送信息提取是信息检索【4】和数据分析【5】中的一个重要环节。在商业、科研等领域，对电子邮件抄送信息的分析可以帮助我们了解通信网络、挖掘潜在的商业机会【6】等。Snobol4语言作为一种高效的文本处理工具，在处理这类问题时具有独特的优势。
二、Snobol4语言简介
Snobol4是一种高级编程语言，由David J. Farber和Ralph E. Griswold于1962年设计。它以处理文本数据著称，具有简洁、易读和强大的文本处理能力。Snobol4语言的特点如下：
1. 简洁的语法：Snobol4的语法相对简单，易于学习和使用。
2. 强大的文本处理能力：Snobol4提供了丰富的文本处理函数，如模式匹配【7】、替换【8】、删除【9】等。
3. 高效的执行速度【10】：Snobol4的程序通常运行得非常快，尤其是在处理大量文本数据时。
