Content Segmentation​

You can segment the text content after uploading. On the segmentation settings page, you can either use the default automatic segmentation or customize it.

Segmentation

  • Segmentation Identifiers: These identifiers are used to split long texts or complex data into smaller sections so that each paragraph, sentence, or data block can generate independent embedding vectors. The following identifiers are supported:

    • Line Break
    • Chinese Period
    • Chinese Exclamation Mark
    • Chinese Question Mark
    • English Period
    • English Exclamation Mark
    • English Question Mark

  • Maximum Segmentation Length: The supported range is [100, 800].

  • Text Preprocessing Rules: Preprocessing the text before generating embeddings is a key step to ensure the input is suitable for generating high-quality vector representations. The following rules are currently supported:

    • Replace consecutive spaces, line breaks, and tabs.
    • Remove all URLs and email addresses.

After segmentation, you can view the segmented content on the knowledge base page.

If re-segmentation is needed, click the settings icon in the upper-right corner of the knowledge base page to enter the re-segmentation page.
