20Q

The 20Q AI can draw its own conclusions on how to interpret the information. It can be described as more of a [[folk taxonomy]] than a [[Taxonomy (general)|taxonomy]]. Its knowledge develops with every game played. In this regard, the online version of the 20Q AI can be inaccurate because it gathers its answers from what people ”think” rather than from what people ”know”. Limitations of taxonomy are often overcome by the AI itself because it can learn and adapt. For example, if the player was thinking of a “Horse” and answered “No” to the question “Is it an animal?,” the AI will, nevertheless, guess correctly, despite being told that a horse is not an animal.
