The detailed documentation for this Q & A matching example includes the step-by-step walk-through: https://docs.microsoft.com/azure/machine-learning/preview/scenario-qna-matching

The public GitHub repository for this Q & A matching example contains all the code samples: https://github.com/Azure/MachineLearningSamples-QnAMatching

This example addresses the problem of mapping user questions to pre-existing Question & Answer (Q&A) pairs as is typically provided in a list of Frequently Asked Questions (that is, a FAQ) or in the Q&A pairs present on websites like Stack Overflow. There are many approaches to match a question to its correct answer, such as finding the answer that is the most similar to the question. However, in this example open ended questions are matched to previously asked questions by assuming that each answer in the FAQ can answer multiple semantically equivalent questions.

The key steps required to deliver this solution are as follows:

1. Clean and process text data.
2. Learn informative phrases, which are multi-word sequences that provide more information when viewed in sequence than when treated independently.
3. Extract features from text data.
4. Train text classification models and evaluate model performance.

1. An Azure account (free trials are available).
2. An installed copy of Azure Machine Learning Workbench with a workspace created.
3. This example could be run on any compute context. However, it is recommended to run it on a multi-core machine with at least of 16-GB memory and 5-GB disk space.
