What types of chunking (text segmentation) exist?

Chunking is the process of dividing text into parts (chunks) for easier processing. The main types of chunks:

• By characters — a fixed number of characters in each chunk.
• By words — splitting by spaces or other delimiters, with chunks containing a certain number of words.
• By sentences — dividing the text into sentences, for example, by periods, exclamation marks, and question marks.
• By paragraphs — dividing by line breaks or other paragraph markers.
• By semantic units — for example, highlighting topics or subtopics, which requires semantic analysis.

The choice of method depends on the task: for natural language processing, splitting by sentences or words is often used; for streaming, by fixed sizes.
