eShopSupport Series: EvaluationTests Project

This is the seventh part of the eShopSupport Series which covers the details of the eShopSupport GitHub repository. NOTE: This entry will make the most sense to you if you’ve first read eShopSupport: Evaluator Project EvaluationTests Project The EvaluationTests project is a recently added xUnit Test Project that uses the new Microsoft.Extensions.AI.Evaluation packages highlighted in this blog: Evaluate the quality of your AI applications with ease. I think the idea is to replace the Evaluator project but, as is, it doesn’t run all 500 evaluation questions in the dev folder (which is good since it would not be cheap to do unless you are running locally). The good news is: the EvaluationTests project is a good example of how to use the new Microsoft.Extensions.AI.Evaluation …

eShopSupport Series: Python Inference Project

This is the fifth part of the eShopSupport Series which covers the details of the eShopSupport GitHub repository. PythonInference Project The PythonInference Project is a python project that provides a web API to classify the case type when a new customer support ticket is entered in the system.

eShopSupport Series: Evaluator Project

This is the third part of the eShopSupport Series which covers the details of the eShopSupport GitHub repository. Evaluator Project The Evaluator project is a console application used to evaluate the chat portion of the application provided by the AssistantApi in the Backend project. The Evaluator application uses the questions in the evalquestions.json file to test the assistant API and scores the results it returns against the answers in that JSON file. This gives you the ability to measure the quality of the chat functionality - which is an important thing to do when you are building application functionality that depends on an LLM. The Evaluator project is located in in the src folder: In this entry I’ll cover the details of how the Evaluator application works, a few things I …

eShopSupport Series: DataIngestor Project

This is the second part of the eShopSupport Series which covers the details of the eShopSupport GitHub repository. DataIngestor Project The DataIngestor is a console application that will process the data files created by the DataGenerator - it does not ingest the data into any of the databases. I mentioned in the last entry about the DataGenerator that you didn’t need to use the DataGenerator because there are two sets of generated files provided in the github repo: dev and test. What I failed to mention is those files are result of both the DataGenerator and the DataIngestor being run. So you also don’t have to use the DataIngestor. The DataIngestor project is located under the src folder: In this entry I’ll cover the details of what the DataIngestor application does, a …

eShopSupport Series: DataGenerator Project

This is the first part of my eShopSupport Series which looks into the details of the eShopSupport GitHub repository. DataGenerator Project The DataGenerator is a console application that will generate multiple types of seed data files for loading into the application or to use when evaluating the question answering functionality. However, you don’t have to use the DataGenerator - there are two sets of generated files provided in the github repo: dev and test. In this entry I will provide some detail of what the DataGenerator application does, some interesting things about it and a few things I’d like to change. What does it do? This project is introduced about 16 minutes into Steve Sanderson’s talk How to add genuinely useful AI to your webapp (not just chatbots), where …

eShopSupport Series

Announcing: The eShopSupport Series In case you missed this week’s .NET Conf Focus on AI you can find all the videos on the dotnet YouTube channel. The one I want to point out here is: Better Together: .NET Aspire and Semantic Kernel with Steve Sanderson and Matthew Bolanos. Steve’s portion of the talk is a distilled version of his NDC talk earlier this year: How to add genuinely useful AI to your webapp (not just chatbots) where he introduced the eShopSupport project. If you are a .NET developer looking for ways to use AI in real world applications - you should absolutely watch that video. Starting next week, I will be digging into the eShopSupport codebase and blogging about it. Since it isn’t a RAG application - I don’t think it fits into the RAG Demo Series so I …
