Keyword matching is a basic technique in Natural Language Processing (NLP) used to identify specific words or phrases (keywords) in text and take action based on their presence. It’s often used in tasks like:
-
Information retrieval (e.g., search engines)
-
Rule-based chatbots
-
Spam detection
-
Form or intent recognition
🔑 How Keyword Matching Works:
It typically involves:
-
Predefined Keywords: A list of words/phrases you’re interested in.
-
Text Scanning: The system scans the input for matches.
-
Action or Labeling: Based on detected keywords, it assigns a label, triggers a response, etc.
