| Abstract(in English) | We propose word-based block sorting, which is used for compressing both texts and their full-text indexes, inverted files. Since texts are separated into words, morphological analysis, which is time consuming, is not necessary in the decoder. By using the proposed compression scheme, we can reduce space for storing full-text indexes and a load for transferring them via network. We also propose an algorithm for creating an inverted file from a compressed file by the ordinary block sorting which has better compression ratio than the word-based block sorting. |
