Abstract
A method of automated ranking of segments of learning materials includes calculating a window similarity between first-window content of a first window in a learning material and second-window content of a second window in the learning material. The method may also include in response to the window similarity between the first-window content of the first window and the second-window content of the second window meeting a similarity threshold, generating a first segment that includes at least the first-window content and the second-window content. The method may include calculating a first-segment consistency measurement for the first segment based on a first-segment similarity between the first-segment content in the first segment and a knowledge point. The method may also include ranking the first segment with respect to one or more of the following: a second segment in the learning material and a third segment in a different learning material, wherein the ranking of the first segment is based on one or more of the following: a quality measurement, a learning material type of the learning material, a length of the first segment, and the first-segment consistency measurement of the…
