| Abstract: | In this paper we try to prove that some classes of inverted file systems are equivalent to a Data Base System based on data processing functions.We show that if we can build a full, well-structured inverted file system, that file system takes on the effect and the efficiency of a Data Base System, for Chinese Information Retricval System. Then, from the constructive principle of the inverted file system,we may obtain the following theorem: ACS (EFB~*(?) |
