Resumo inteligente de documentos - Object Storage Service: Central de Documentação do Alibaba Cloud

O resumo inteligente de documentos condensa automaticamente textos longos em sínteses breves que destacam os pontos principais. Esse processo elimina a necessidade de leitura integral e permite compreender rapidamente o conteúdo.

Pré-requisitos

Vincule o bucket do Object Storage Service (OSS) correspondente a um projeto do Intelligent Media Management (IMM). Para vincular um bucket do OSS a um projeto do IMM no console do OSS, consulte Início rápido. Para fazer essa vinculação pela API do IMM, consulte AttachOSSBucket.

Observações de uso

O resumo inteligente de documentos suporta apenas processamento síncrono (x-oss-process).
Para usar esse recurso, envie requisições com o método POST.
