Best way to identify product number using LUIS with Microsoft Bot Framework

Question

Im using LUIS Microsoft Bot Framework and Node.js to program a Bot.

If i ask my bot: "Get me product WKJ UJK HYF"

What is the best way to identify the product identification "WKJ UJK HYF" and determining the intent?

i have tried using regexp but i can't get it right. And what if someone tries: "Get me product WKJUJKHYF"

how can i cover these 2 scenarios in a good way?

i have tried using the regexp: "^[a-zA-Z\s]{9,12}$" but LUIS fails and thinks that only the 3 first letters are the product, and it also gives me an entity containing numbers (like "YHJ123455").

Answer 1

The problem could be solved by providing more examples with different patterns to make the model flexible. Examples:

• get me product ID
• show me ID
• price of ID
• etc...

Also you can provide some product IDs as a phrasal list feature to make LUIS familiar with their patterns.
