Entities are pieces of information that provide helpful context about what someone is saying in a conversation. They are words or phrases that refer to specific types of details like names, dates, locations, numbers, and so on.
For example, in the sentence "I want to book a flight from Chicago to Miami on June 15th", the entities would be:
- Chicago (departure place)
- Miami (arrival place)
- June 15th (date)
Identifying and extracting these entities correctly is an important task for conversational AI systems and chatbots. It allows them to understand the specific details and intent behind the user's message.
Most conversational AI tools can automatically recognize common entity types that are defined and customized for different use cases. More sample conversations are used to train the system to accurately find entities.
