Como traduzir conteúdo

Como usar a API Cloud Translation - Advanced

Depois de treinar o modelo, é possível traduzir o conteúdo usando o método translateText da API Cloud Translation - Advanced. A API Cloud Translation - Advanced é compatível com o uso de glossários e solicitações de tradução em lote.

REST e linha de comando

Certifique-se de ter ativado a API Cloud AutoML para o projeto. Isso é necessário ao usar modelos do AutoML com a API AutoML. Para ativar a API, veja este documento sobre os Primeiros passos.

Antes de usar os dados da solicitação abaixo, faça as substituições a seguir:

  • project-number-or-id: pelo número ou o código do seu projeto do Google Cloud

Método HTTP e URL:

POST https://translation.googleapis.com/v3/projects/project-number-or-id/locations/us-central1:translateText

Corpo JSON da solicitação:

{
  "model": "projects/project-number-or-id/locations/us-central1/models/TRL1395675701985363739",
  "sourceLanguageCode": "en",
  "targetLanguageCode": "ru",
  "contents": ["Dr. Watson, please discard your trash. You've shared unsolicited email with me.
  Let's talk about spam and importance ranking in a confidential mode."]
}

Para enviar a solicitação, escolha uma destas opções:

curl

Salve o corpo da solicitação em um arquivo chamado request.json e execute o comando a seguir:

-H "Content-Type: application/json; charset=utf-8" \
-d @request.json \
https://translation.googleapis.com/v3/projects/project-number-or-id/locations/us-central1:translateText

PowerShell

Salve o corpo da solicitação em um arquivo chamado request.json e execute o comando a seguir:

Como usar o AutoML Translation

Também é possível usar o AutoML Translation para traduzir conteúdo usando modelos personalizados.

IU da Web

  1. Acesse a página Modelos do AutoML Translation no Console do Google Cloud.

  2. Se o modelo que você quer usar estiver localizado em outro projeto, selecione o projeto no seletor de projetos na barra de título.

  3. Na lista de modelos, selecione aquele que você usará para traduzir o texto.

  4. Clique na guia Prever do modelo.

  5. Na caixa de texto, digite o conteúdo a ser traduzido e clique em Traduzir.

    É possível comparar os resultados do seu modelo personalizado com o modelo base (modelo NMT do Google), que o Cloud Translation - Advanced usa por padrão.

REST e LINHA DE CMD
