This invention relates to a method for the lossless compression of text character documents, comprising the steps of (1) lossy pattern matching, using a new entropy-based threshold function in order to generate contexts (skew numbers); and (2) arithmetic coding of the mismatch between characters and a library reference character, using the reference character as the context.
