RAVENBILL

Couple month ago I discovered a wonderful piece of software - QNAMaker.AI. It allows to build a chatbot based on "Questions and Answers" - a table that has 2 columns - one column contains question and second - corresponding answer. This table is often referenced as Knowledge Base (KB). Service provides a web-based editor for Knowledge Base, test page for playing with "QnA" chatbot produced from KB, import/export between Knowledge Base and Excel spreadsheet and ability to start engine with the customer knowledge base as a separate Azure web application... After deploying QNA Maker .AI I looked how it is deployed and what is going under the hood. What I found was a Windows machine with combination of .NET and Python NLP applications. Wandering in command shell I stumble upon the configuration file claiming that return value is a weighted sum of 3 similarity scores TF-IDF (0.1), Wordnet (0.5) and AzureSearch (0.4). Then I run a simple test from my machine to QNA Maker.
