Intelligent document summarization - Object Storage Service

Smart document summarization automatically condenses long documents into brief summaries that highlight key points of the documents. This process saves readers the effort of reading the full documents and enables them to quickly grasp the content.

Prerequisites

The corresponding Object Storage Service (OSS) bucket is bound to an Intelligent Media Management (IMM) project. For more information about how to bind an OSS bucket to an IMM project in the OSS console, see Quick start. For more information about how to bind an OSS bucket to an IMM project by using the IMM API, see AttachOSSBucket.

Usage notes

Intelligent document summarization supports only synchronous processing (x-oss-process).
To use the intelligent document summarization feature, you must use the POST method to send requests.
Anonymous access will be denied.
You must have the required permissions to use the feature. For more information, see permissions.

Parameters

Action: doc/summarize

The following table describes the parameters that you can specify when you use the intelligent document summarization feature.

Parameter

Type

Required

Description

content

string

Yes

The content that you want to summarize. The content must be encoded in URL-safe Base64.

Note

The content can be up to 19,500 bytes in length.

format

string

The mode to return the response. Valid values:

json (default): the regular mode. A data packet that contains the complete response is returned.
event-stream: the server-sent events (SSE) mode. Multiple packets are returned. Each packet contains full data.

The following table describes the response parameters.

Parameter	Type	Description
RequestId	string	The request ID.
Output	struct	The output. Child nodes: Text and FinishReason
Text	string	The summary. Parent node: Output
FinishReason	string	The status of the summarization task. Valid values: null: The task is running. stop: The task ended. Parent node: Output

Use the RESTful API

Note

If you use the RESTful API to summarize a document, you must specify the document name, which is used only as a placeholder. Intelligent document summarization only identifies the value of the content parameter as the text to be summarized.

Summarize documents in regular mode

Processing method

Document to be processed: example.doc
Text to be summarized: Ernest Hemingway's "The Old Man and the Sea" is a tale of an old fisherman, Santiago, and his epic struggle to catch a giant marlin. This story is a profound exploration of human endurance, perseverance, and the battle against the forces of nature. Santiago's unwavering determination and dignity in the face of adversity serve as a testament to the strength of the human spirit.
Response format: JSON
