Spatial Reasoning
摘要
Language understanding is often associated with the ability to reason over linguistic expressions. However, providing a formal definition of understanding remains a persistent challenge. When language is considered in isolation–separated from other modalities–spatial reasoning over text can be informally defined as follows. Given a piece of text, an agent is said to perform spatial reasoning if it can answer all possible where questions that are supported by the information contained in the text. In the simplest cases, these where questions can be answered by directly extracting explicitly stated spatial information.
