1. Price and Cost Questions – niche: clothing

(?i)(?=.*(?:^|[^a-zA-Z])(?:price|cost|worth|how[ ]?much|amount)[a-zA-Z]*(?:[^a-zA-Z]|$))(?=.*(?:^|[^a-zA-Z])(?:cloth|dress|jacket|jean|shirt|suit)[a-zA-Z]*(?:[^a-zA-Z]|$))(?!.*(?:^|[^a-zA-Z])(?:expensive|high|low|chang|increas|reduc)[a-zA-Z]*(?:[^a-zA-Z]|$)).*

Response: “Our clothing prices start from $30. T-shirts: $30-50, shirts: $50-80, jeans: $60-120, dresses: $70-140, suits: $140-300. We offer a discount system for regular customers. The full price list can be viewed on our website shop.example.com/price.”

Status: “Price inquiry”

Let’s break down this regular expression part by part to understand how it works:

What is a Regular Expression?

Imagine it as a complex filter that checks whether text follows certain rules. In this case, we’re using it to automatically understand when a customer is asking about the price of clothing.

Dissecting the Regular Expression:

• (?i):
  • This means the search will be case-insensitive. So, “Price,” “price,” and “PRICE” will be treated the same.
• (?=.*(?:^|[^a-zA-Z])(?:price|cost|worth|how[ ]?much|amount)[a-zA-Z]*(?:[^a-zA-Z]|$)):
  • This is a “positive lookahead.” It checks if the text contains words related to price.
  • .* means “any number of any characters.”
  • (?:^|[^a-zA-Z]) means “the beginning of the line or any character other than English letters.” This prevents words from sticking together.
  • (?:price|cost|worth|how[ ]?much|amount) means “one of the following words: ‘price,’ ‘cost,’ ‘worth,’ ‘how much,’ or ‘amount.'”
  • [a-zA-Z]* means “any number of English letters.” This accounts for different word forms (e.g., “prices,” “costs”).
  • (?:[^a-zA-Z]|$) means “any character other than English letters, or the end of the line.”
• (?=.*(?:^|[^a-zA-Z])(?:cloth|dress|jacket|jean|shirt|suit)[a-zA-Z]*(?:[^a-zA-Z]|$)):
  • This is another “positive lookahead.” It checks if the text contains words related to clothing.
  • (?:cloth|dress|jacket|jean|shirt|suit) means “one of the following words: ‘cloth,’ ‘dress,’ ‘jacket,’ ‘jean,’ ‘shirt,’ or ‘suit.'”
• (?!.*(?:^|[^a-zA-Z])(?:expensive|high|low|chang|increas|reduc)[a-zA-Z]*(?:[^a-zA-Z]|$)):
  • This is a “negative lookahead.” It checks if the text doesn’t contain words that express price evaluations (e.g., “expensive,” “cheap”).
• .*:
  • At the end of the expression, this means “any number of any characters.”

How it Works in Practice:

When a customer writes a message, the regular expression checks if it meets all the conditions:

• Does the message contain words related to price?
• Does the message contain words related to clothing?
• Does the message not contain words that evaluate price?

If all conditions are met, the customer is likely asking about the price of clothing.

Example:

• Message: “How much is the dress?”
  • Regular expression: “Yes, this is a price inquiry about clothing.”
• Message: “Your prices are too high.”
  • Regular expression: “No, this is a price evaluation, not an inquiry.”

Why Is This Useful?

This allows you to automate responses to frequently asked questions. For instance, you can set up an auto-reply that automatically sends clothing price information when a customer asks a relevant question.
