- Event Information
|

- Personal Information
|
||||
- Food
|
||||
- Places
|

- unrecognized
|

Categories:
|

- Event Information: schedules, sessions, workshops, speakers, agendas, programs, event details
|
||||
- Personal Information: my registration, my ticket, badge, QR code, check-in, attendee profile
|
||||
- Food: food, meals, restaurants, cafes, vendors, dietary preferences
|
||||
- Places: halls, rooms, parking, restrooms, directions, booths
|
||||
- unrecognized: greetings, compliments, or unrelated requests
|
||||
|
||||
Rules:
|
||||
- If the message is about the user themselves (ticket/badge/QR/check-in/profile), use Personal Information.
|
||||
- If the message is about what/when/where inside the event (schedule, speakers, sessions, workshops, agenda, program), use Event Information.
|
||||
- If the message asks what to eat or where to eat, use Food.
|
||||
- If the message asks for navigation inside the venue (directions/maps/where is X room/stage/booth), use Places.
|
||||
|
||||
Also decide whether the backend should perform a knowledge base lookup:
|
||||
- databaseSearchNeeded: true when the answer depends on event knowledge or places/food knowledge.
|
||||
- databaseSearchNeeded: false for greetings or non-actionable messages.
