This repository contains the results of two benchmarks that compare natural language understanding services offering:

1. built-in intents (Apple’s SiriKit, Amazon’s Alexa, Microsoft’s Luis, Google’s API.ai, and Snips’ SDK) for the intents covered by the Snips SDK. This benchmark was performed in December 2016. Its results are described in length in the following post.
2. custom intent engines (Google's API.ai, Facebook's Wit, Microsoft's Luis, Amazon's Alexa, and Snips' NLU) for seven chosen intents. This benchmark was performed in June 2017. Its results are described in the following post.

The data is provided for each benchmark and more details about the methods are available in the README file in each folder.
