Keyword Classifier

Classify a text into one of three categories based on keyword matching:

• sports: contains any of ["goal", "team", "player", "match", "score"]
• tech: contains any of ["code", "software", "computer", "algorithm", "data"]
• food: contains any of ["recipe", "cook", "ingredient", "meal", "dish"]

Check categories in the order: sports → tech → food. Return the first matching category. If no keywords match, return "other".

All matching is case-insensitive and checks if the keyword appears as a whole word in the text.

Input: A single line of text.
