Snobol4【1】 语言实战：开发文本查重【2】与相似性分析【3】工具

Snobol4 是一种古老的编程语言，最初于1962年由David J. Farber、Ralph E. Griswold 和 Ivan P. Polonsky 设计。尽管它已经不再流行，但Snobol4 在文本处理方面有着独特的优势。本文将探讨如何使用Snobol4 语言开发一个简单的文本查重与相似性分析工具。

Snobol4 简介

Snobol4 是一种高级编程语言【4】，特别适合于文本处理任务。它具有以下特点：

- 强大的字符串处理【5】能力
- 简洁的表达式语法
- 高效的运行速度

文本查重与相似性分析

文本查重与相似性分析是计算机科学中的一个重要领域，广泛应用于学术不端检测【6】、版权保护【7】、内容推荐【8】等场景。本文将介绍如何使用Snobol4 实现这一功能。

1. 数据准备

我们需要准备一些文本数据。以下是一些示例文本：

plaintext
Text 1: The quick brown fox jumps over the lazy dog.
Text 2: A quick brown dog outpaces a lazy fox.
Text 3: The quick brown fox jumps over the lazy dog.
Text 4: A quick brown fox jumps over a sleeping dog.

2. Snobol4 代码实现

以下是一个简单的Snobol4 代码示例，用于实现文本查重与相似性分析：
