Document splitters behavior

General splitter behavior

Splitter output contains split information for the input document, including a confidence score. The Document AI API outputs a Document JSON object, and the output format uses the entities field for representing document splits. Additional information depends on the specific type of splitter.

• Entity.type specifies the document classification. For a full list of document types that can be identified, see the following lists.

• Entity.pageAnchor.pageRefs[] specifies the pages that contain each sub-document. Note that pageRefs[].page is zero-based and is the index into the document.pages[] field.

  Caution: Zero pageRefs[].page values omitted. When the API detects a page value of "0", that coordinate is omitted in the JSON response. For example, a response for the first two pages of a document would be: "pageRefs": [{}, {"page": "1"}]

The splitter is not designed to split logical documents that are over 30 pages long. Logical documents that are more than 30 pages long (e.g. a 40-page bank statement) may be split into two or more docs and classified separately.

Splitters identify page boundaries, but do not actually split the input document for you. Here is a code sample that physically splits a PDF file by using the page boundaries:
