19、基于字符的语言模型构建与文本生成

基于字符的语言模型构建与文本生成

1. 引言

在自然语言处理领域，语言模型是一项重要的技术，它可以学习文本的统计规律，从而实现文本生成等功能。本文将详细介绍如何使用一首著名的英文童谣《Sing a Song of Sixpence》来构建一个基于字符的语言模型，并使用该模型生成新的文本。

2. 数据准备

2.1 选择童谣文本

《Sing a Song of Sixpence》这首童谣在西方广为人知，我们将使用其完整的4节版本作为源文本。以下是完整的童谣内容：

Sing a song of sixpence,
A pocket full of rye.
Four and twenty blackbirds,
Baked in a pie.
When the pie was opened
The birds began to sing;
Wasn't that a dainty dish,
To set before the king.
The king was in his counting house,
Counting out his money;
The queen was in the parlour,
Eating bread and honey.
The maid was in the garden,
Hanging out the clothes,
When down came a blackbird
And pecked off her nose.

将上述文本复制到一个新文件中，保存为 rhyme.t
