At Microsoft Ignite, 3rd November 2021, we announced the new Question Answering feature within the Cognitive Service for Language. This capability is the newer and improved version of the erstwhile standalone QnA Maker. Following this launch, the QnA Maker service was put on a retirement path, with the deprecation date set as March 31, 2025.
This article aims to answer a few common questions around this announcement.
Q. What is Question Answering?
A. Powered by state-of-the-art transformer models and Turing natural language model, Question Answering is Microsoft Azure’s latest intelligent Q&A offering with marked improvements in relevance and quality over QnA Maker. For instance, while Question Answering has the same custom Q&A capabilities familiar in QnA Maker, it also introduces a new capability to query a text passage and get a response without having to manage knowledge bases, using prebuilt question answering models.
Q. Why is QnA Maker being retired?
A. QnA Maker became Generally Available in 2018. Since then, we have seen good engagement and feedback from our customers. However, given new advancements in computation capabilities and natural language models, the old QnA Maker service needs to be retired and replaced with a new architecture to bring you the best of Azure’s Language capabilities.
Question Answering will have a much-simplified architecture, which will remove the requirement to host a separate App Service, thus making the management of the service easier. The other benefit is that customers will only need to pay for the service and Azure Cognitive Search. For QnA Maker, customers had to pay an additional cost for Azure App Service.
