Abstract: Disclosed are methods and the non-transitory computer storage media of extracting linguistic patterns and summarizing a pathology report thereof. The present disclosure provides a method of extracting key linguistic patterns from a pathology report. The method comprises: determining a confidence degree and a support degree between a linguistic term and a next linguistic term based on co-occurrences of the linguistic term and the next linguistic term; generating a set of candidate linguistic terms; generating a first set of linguistic patterns through performing random walks on the set of candidate linguistic terms; and determining the key linguistic patterns through removing redundant linguistic patterns from the first set of linguistic patterns.
