three main underlying intents, namely navigational, informational, and transactional.
There exist two main “dimensions” in which query classification has been usually performed: “topic” and “intent”.
topic: movie, travel, news etc
intent:
  1. “navigational” (the user wants to reach a particular website),
  2. “informational” (the user wants to find a piece of information on the Web), and (3)
  3. “transactional” (the user wants to perform a web-mediated task).
