Title:
METHOD AND APPARATUS FOR COMPRESSION INDEXING OF CHARACTER STRING SEQUENCES
Document Type and Number:
WIPO Patent Application WO/2017/161589
Kind Code:
A1
Abstract:
A method and apparatus for compression indexing of character string sequences, relating to the technical field of data management, and solving the problems in existing CS-Prefix-Tree code indexing processes of the reduced accommodating capacity of code indexing branch nodes and the increased number of branch nodes and search complexity as a result of excessively long differential prefix lengths in bottom layer leaf nodes. The method comprises: grouping a character string sequence on the basis of the differential prefix length of every character string in the character string sequence to acquire M character string groups, such that the differential prefix length of the first character string in the character string group is the shortest in a preset character string range (S102); storing the M character strings in sequence in N internal memory pages (S103): and constructing a hopping table index on the basis of index keywords of the N internal memory pages (S104).
