Integration: Azure Translate Nodes

TranslateAnswer and TranslateQuery Nodes that use the Azure Translate endpoint

Authors
recrudesce (Russ)

This package allows you to use the Azure translation endpoints to separately translate the query and the answer. It’s good for scenarios where your dataset is in a different language to what you expect the user query to be in. This way, you will be able to translate the user query to the your dataset’s language, and translate the answer back to the user’s language.

Installation

Run pip install haystack-translate-node to install the latest available version.

Usage

Include in your pipeline as follows:

from haystack_translate_node import TranslateAnswer, TranslateQuery

translate_query = TranslateQuery(api_key="<yourapikey>", location="<yourazureregion>", azure_translate_endpoint="<yourazureendpoint>", base_lang="en")
translate_answer = TranslateAnswer(api_key="<yourapikey>", location="<yourazureregion>", azure_translate_endpoint="<yourazureendpoint>", base_lang="en")

pipel = Pipeline()
pipel.add_node(component=translate_query, name="TranslateQuery", inputs=["Query"])
pipel.add_node(component=retriever, name="Retriever", inputs=["TranslateQuery"])
pipel.add_node(component=prompt_node, name="prompt_node", inputs=["Retriever"])
pipel.add_node(component=translate_answer, name="TranslateAnswer", inputs=["prompt_node"])

location, azure_translate_endpoint, and base_lang are optional, and will default to uksouth, https://api.cognitive.microsofttranslator.com/, and en respectively.

TranslateQuery will determine the language of the query, and assign it to the in_lang JSON value.

TranslateQuery will take the original query, in any language, and assign it to the in_query JSON value.

TranslateQuery will overwrite the original query JSON value with the translated English value

You can then query your base_lang corpus using the query value as normal using a standard Haystack Retriever node, which will place your results in results.

TranslateAnswer translate the base_lang result stored in results back to the language stored in in_lang and subsequently store it in the out_answer JSON value.
