English Abstract
This thesis is concerned with the development and performance evaluation of a new adaptive bit-level text compression scheme that is based on the Hamming Codes Data Compression (HCDC) algorithm.
The HCDC algorithm is a lossless binary (bit-level) data compression algorithm that utilizes the well-known error correcting Hamming codes.
The new scheme consists of six steps some of which are applied repetitively to enhance the compression ratio.
The repetition loops continue until inflation is detected.
The overall (accumulated) compression ratio is the multiplication of the compression ratios of the individual loops, therefore we refer to this new scheme as HCDC(k), where k refers to the number of repetition loops.
In the HCDC(k) scheme, a new adaptive text-to-binary coding format was developed and used.
This method of coding reduces the entropy of the generated binary sequence so that it grants higher compression ratio.
The HCDC(k) scheme was implemented in C++ programming language; and used to compress a number of text files from standard corpora.
The results obtained demonstrate that the HCDC(k) scheme has higher compression ratio than most well-known text compression algorithms, and also exhibits a competitive performance with respect to many widely-used state-of-the-art software.
Finally, the results obtained are discussed, conclusions are drawn, and recommendations for future work are pointed-out.
