A MUST read article on Dialogflow training phrase quality

Recently, Google published a very interesting article on how you can assess the quality of the training phrases inside your Dialogflow agent.

In my view, if you are at all interested in building a Dialogflow agent, it is a MUST READ. Note: You do need a fairly good programming background, plus some basic understanding of concepts such as “word vectors” to understand that article. So maybe the person who will read it is the programmer on your team.

But here is the gist of it: you should maximize cohesion as well as separation in your intents.

In this context, what is cohesion and what is separation? Instead of repeating what is already mentioned in that article, I will just highlight the definition in the screenshot image.

In early 2018, I released my Dialogflow Conversation Design course. People who bought the course might remember these suggestions I had in the course for designing intent training phrases.

Minimize Intra-intent variation

Maximize Inter-intent variation

If you follow the definitions of cohesion and separation, it is quite clear that the terminology I used overlaps with their definitions.

However, I didn’t know that there was a more succinct and mathematical way to define these concepts. Plus, the Google article actually quantifies what I could only “qualitatively” observe at that time.

Agent Validation feature

Have you seen Dialogflow’s new agent validation feature?

In fact, when you look at the agent validation for the prebuilt Smalltalk agent, you see this suggestion:

My guess is that the approach explained in the article is what is being used for this feature.

You can learn more about the agent validation feature in my course.

Three things you can infer from the article

There are three things you can infer from that article:

But the real point I am making – other than the blatant plug for my courses 😉 – is that this is an acknowledgment from Google that you need to also help Dialogflow if you want Dialogflow to help you.

"The magic key I needed as a non-programmer"

The custom payload generator was the magic key I needed (as a non-programmer) to build a good demo with rich responses in DialogFlow Messenger. I've only used it for 30 minutes and am thrilled. I've spent hours trying to figure out some of the intricacies of DialogFlow on my own. Over and over, I kept coming back to Aravind's tutorials available on-line. I trust the other functionalities I learn to use in the app will save me additional time and heartburn.

"Much clearer than the official documentation to be honest"

Thanks a lot for the advice (of buying and following your videos)! They helped a lot indeed. Everything is very clear when you explain, much clearer than the official documentation to be honest 🙂

"I will strongly recommend this course because even I can learn how to design chatbot (no programming background)"

I think Aravind really did a great job to introduce dialogflow to people like me, without programming background. He organizes his course in very clear manner since I have been a college professor for 20 years. It is very easy for me to recognize how great Aravind’s course is! Very use-friend and very easy to follow. He doesn’t have any strong accent when he gives the lectures. It is so easy for me to understand. Really appreciate it.

Yes, I will strongly recommend this course because even I can learn how to design chatbot (no programming background) after studying Avarind’s course, you definitely can!
