This Google patent describes methods and systems for extracting structured information from unstructured text. The core idea involves parsing text into a tree-like structure based on the grammatical roles of words (parts of speech), then identifying paths within that tree that connect entities (such as people or places) to values (such as schools or capitals) through specific attributes (such as “alma mater” or “country capital”). Once these tree paths are discovered using known example facts, they can be reused to automatically extract new, previously unknown facts from the same or different text sources. The patent also covers validation techniques to ensure that extracted paths and facts are accurate and reliable.
