How does Wolfram Alpha ensure accuracy?

Wolfram Alpha ensures accuracy through a meticulous process of curating and collecting data to ensure it is as true as possible. According to Stephen Wolfram, they focus on handling real-world data by verifying factual information that can be computationally processed. For example, regarding questions about facts such as Oscar winners or scientific measurements, Wolfram Alpha uses definitive sources to provide accurate computations. This emphasis on reliable data sources and symbolic reasoning allows Wolfram Alpha to maintain a high standard of accuracy, although it cannot guarantee truth in all contexts, especially subjective matters 1.
