Creation and recovering of the pseudo-code (Y) form the basis of the present method of text compression and decompression. The pseudo-code includes information of a repeating index/symbol (constant C) and a current index/symbol (X). To service the pseudo-code one needs to convert original symbols of text into indexes and to create a permanent and temporary vocabulary. The present permanent vocabulary is a redundant vocabulary built in advance includes dictionary with common symbols taken from books, articles, and dictionaries, and serves as a reference vocabulary stored in the permanent memory. The temporary vocabulary is built and is used during compression and decompression processes. The functionality of the temporary vocabulary is to convert a high bit length of indexes belonging to the permanent vocabulary into a low bit length indexes present in the temporary vocabulary. |
