Text Corpus

What Is a Text Corpus for Machine Learning?

A text corpus for machine learning refers to supervised training data—such as text and speech—used to build applications like chatbots and command-based systems for electronic devices.
In some cases, this type of training data can be collected from existing resources, including FAQ pages on corporate websites, customer support chat scripts, call logs, and emails from contact centers.
However, when existing data is limited or insufficient, we invite you to leverage our ready-to-use text corpus datasets, designed to support efficient and scalable AI development.
