Snobol4 语言实现文本查重系统实战
文本查重系统是现代信息时代中非常重要的工具，它可以帮助我们检测文本内容的原创性，防止抄袭和剽窃。Snobol4 是一种古老的编程语言，以其简洁和强大的文本处理能力而闻名。本文将探讨如何使用 Snobol4 语言实现一个简单的文本查重系统。
Snobol4 简介
Snobol4 是一种高级编程语言，由Ralph E. Griswold在1962年发明。它特别适合于文本处理任务，如模式匹配、字符串操作和文本分析。Snobol4 的语法简洁，易于理解，这使得它在文本处理领域有着广泛的应用。
文本查重系统设计
文本查重系统的核心功能是检测两个文本之间是否存在相似或重复的内容。以下是文本查重系统的大致设计：
1. 文本预处理：对输入的文本进行格式化，如去除空格、标点符号等。
2. 分词：将文本分割成单词或短语。
3. 词频统计：统计每个单词或短语的频率。
4. 相似度计算：比较两个文本的词频统计结果，计算相似度。
5. 结果输出：输出相似度结果，显示两个文本的相似程度。
Snobol4 实现文本查重
以下是一个使用 Snobol4 实现的简单文本查重系统的示例代码：
