Lossless Text Compression using Dictionaries
Umesh S. Bhadade, Abhishek Trivedi · International Journal of Computer Applications · 2011
Compression is used just about everywhere.Reduction of both compression ratio and retrieval of data from large collection is important in today"s era.We propose a pre-compression technique that can be applied to text files.The output of our technique can be further applied to standard compression techniques available, such as arithmetic coding and BZIP2, which yields in better compression ratio.The algorithm suggested here uses the dynamic dictionary created at run-time and is also suitable for searching the phrases from the compressed file.
