Basic Information

Pipeline type: Indexing and Query
When used in an indexing pipeline, it translates documents before they're indexed.
When used in a query pipeline, it translates documents after they're retrieved from a document store.
Type: deepset_cloud_custom_nodes.converters.deepl_document_translator.DeepsetDeepLDocumentTranslator
Components it can connect with:
- Converters: You can use DeepsetDeepLTextTranslator after converters to translate the documents converters return.
- Retrievers: You can use this component to translate documents fetched by a retriever.
- PromptBuilder: DeepsetDeepLTextTranslator can send the translated documents to a PromptBuilder, which then includes them in the prompt for the LLM.

Inputs

Name	Type	Description
`documents`	List of Document objects	A list of documents to be translated.

Outputs

Name	Type	Description
`translated_documents`	List of Document objects	A list of translated documents.

Overview

DeepsetDeepLDocumentTranslator uses the DeepL Python library to translate documents into the languages you specify. For a list of supported languages, see DeepL documentation. You can translate one set of documents into multiple languages at once; just pass the language codes in the target_languages parameter.

Authorization

You must have an active DeepL account and a DeepL API key to use this component. Connect DeepL to deepset Cloud on the Connections page:

Click your initials in the top right corner and select Connections.
Click Connect next to the provider.
Enter your user access token and submit it.

Once deepset Cloud is connected, you can use DeepsetDeepLDocumentTranslator without needing to pass the API key in the pipeline YAML.

Init Parameters

Parameter	Type	Possible values	Description
`target_languages`	List of strings	For a list of possible options, see DeepL documentation.	Codes of languages you want to translate your documents into. Required.
`source_language`	String	Default: `None`	The language of the documents you want to translate. If `None`, it's automatically detected. For a list of possible options, see DeepL documentation. Optional.
`api_key`	Secret	Default: `Secret.from_env_var("DEEPL_API_TOKEN")`	The DeepL API key. Required.
`preserve_formatting`	Boolean	Default: `True`	Controls automatic formatting correction. When `True`, prevents automatic correction of formatting. Optional
`context`	String	Default: `None`	Use this parameter to include additional context that can influence a translation without being translated itself. Providing additional context can potentially improve translation quality, especially for short, low-context source texts such as product names on an e-commerce website, article headlines on a news website, or UI elements. For details, see DeepL API documentation. Optional.
`formality`	String	`less` `more` Default: `None`	Controls whether translations lean toward informal or formal language. This works only for target languages: German (DE), French (FR), Italian (IT), Spanish (ES), Dutch (NL), Polish (PL), Portugese (PT_BR and PT_PT), Japanese (JA), and Russian (RU). Possible values: - `less`: Uses more informal language - `more`: Uses more polite and formal language. Optional.
