Slot Filling

Slot filling is a process used in natural language understanding where a system extracts specific pieces of information from a sentence to complete a structured task. For example, in a travel booking request, the system identifies details like destination, date, and airline company. Think of it as filling in the blanks of a form based on what someone says. This helps virtual assistants, chatbots, and AI to better understand and respond accurately to user requests by pinpointing key details within their language.
