Do-it-yourself NLP for bot developers – Rasa Blog – Medium

I believe in most cases it makes sense for bot makers to build their own natural language parser, rather than using a third party API. There are good strategic and technical arguments for doing this, and I want to show how easily you can put something together. So what NLP do you need for a typical bot? Let's say you're building a service to help people find restaurants. In a previous post I mentioned that tools like wit and LUIS make intent classification and entity extraction so simple that you can build a bot like this during a hackathon.
