Abstract
A method and device for data segmentation in data compression are disclosed. The method includes: acquiring a segmentation rule corresponding to the length of a current unsegmented data stream according to the length of the current unsegmented data stream in a data stream to be compressed, whereas the length of the unsegmented data stream increases, the probability that the corresponding segmentation rule is satisfied increases monotonically, and when the segmentation rule corresponding to a first length is satisfied, the segmentation rule corresponding to a second length is definitely satisfied too; where the first length and the second length are the length of the unsegmented data stream, and the first length is smaller than the second length; and segmenting, by using the segmentation rule, the data stream to be compressed.
