Data Compression Technology In The Uygur, Kazak, Kirgiz Text

As an important problem in the information science, the data compression technology has been given widly attention. The main purpose of data compression is to represent the origin information sent by the information resource with minimum data, thus to decrease the storage space of the information, and to increase the transport speed of it. To some special data, the compressing ration of the existing arithmetics may be very high, bu to others, it may be very low. So, in order to find arithmetic with good integrated capability, it is essential to compare arithmetics according to all factors in application.Data compression technology is divided into lossless data compression and lossy data compression.According to its characteristics in the analysis of this data in the Uighur language text data preprocessing. Analysis HUFFMAN algorithm, the LZW algorithm, LZHUF algorithms and improved ILZW algorithm on the LZW algorithm, the above algorithm using the C#language experiment.Final to select ILZW compression algorithm Minority language text data compression, combined with the Uyghur language features more effective minority text data compression.To accomplish this goal, the main work is as follows:(1) Analysis of a variety of encoding.(2) Pretreatment of the introduction of the language features.(3) Improve the LZW algorithm for ILZW.Compression technology in text compression experiments and practice show that the compression technology, the introduction of recall rate and accuracy of the current search engine.
