A smart device that responds to the question "What is the stock price of Contoso. Ltd.?" is an example of which AI workload?

Knowledge mining involves extracting information from large amounts of unstructured data to create a searchable index or knowledge base, which is a different domain than real-time conversational understanding.

Natural language processing (NLP) is the AI workload involved when a device interprets human language, extracts intent and entities (like "stock price" and "Contoso. Ltd."), and formulates a response based on that understanding. This includes tasks like speech recognition and natural language understanding.

Computer vision deals with enabling computers to "see" and interpret visual data, such as images and videos, which is not directly relevant to understanding spoken questions.

Anomaly detection identifies unusual patterns or outliers in data, a task unrelated to understanding and responding to natural language queries.
