The invention discloses a text structuring method aiming at power grid fault cases. The method includes: subjecting unstructured texts to named entity recognition, and constructing an entity dictionary aiming at the field of power grid to assist in entity recognition and text segmentation; extracting attribute values and attribute description state quantities, wherein the state quantities includedigital state quantities and non-digital state quantities according to types; extracting and matching digital state quantity modification attributes according to a rule-based method; detailing the non-digital state quantities to divide into phrase form based state quantities and sentence form based state quantities, and extracting respective modification attributes; according to recognized attributes and corresponding state quantities, finally generating a plurality of binary groups formed by the attributes and the corresponding state quantities to complete text structuring.
