Starting with AI powered chat

[dada1]

This is my first time trying to build AI chat. I'm trying to create some kind of AI that will be able to chat with humans.

Let me give you an example. Person sends a question or any other sentence and then AI analyses it and responds.

I'm not talking about chatbot, I'm talking about using PHP to build my own chat system. How and where do I start?

This is such a broad field. The real thing is knowing how the whole machine learning and artificial intelligence work behind the scenes. Then it's just a matter of providing an interface.

I could tell you to study machine learning and artificial neural network (RNN) construction, but if the interest is didactic it would be good to start with simple parts, instead of diving into advanced calculations.

You need to find the logical path, try to think how you can understand what someone is typing with you on Whatsapp.

I have an example:

Before you know what to reply, you need to identify the message being conveyed, and not exactly WHAT is written.

So start by simplifying the language. Combining words that have the same meaning and thus standardizing those words.

For example, if I write "You are an incredible person!", The system can identify that it is an exclamation, it identifies the subject (the robot itself) and identifies the adjective "Incredible", so it can draw the conclusion that it is receiving a compliment, then the robot must be "Polite" to respond accordingly.
So start by creating a vocabulary in the database, classifying verbs, adjectives, nouns and subjects ... then start to identify them.

I think it's a good start.
I hope I was helpfull.
