- Abstract
This paper proposed segmentation method optimized by ABC algorithm in ASCS algorithm for the problem of ASCS algorithm, which adopted uniform segmentation instead of optimal segmentation. The ASCS algorithm only considered an influencing factor and ignored the influence of other factors. The ratio of compressing long sequence of uneven distribution was unsatisfactory with ASCS algorithm, it adopted the process integer sequence with sorting and differential encoding before ASCS algorithm. Simulation experiments show that the improved algorithm has significantly increased compression ratio of inverted index file comparing with ASCS algorithm.
