  There is a special type of text which the order of the rows makes no
difference (e.g., a word list). To compress these special texts, the
traditional lossless compression method is not the ideal choice. A new method
that can achieve better compression results for this type of texts is proposed.
The texts are pre-processed by a method named SSE and are then compressed
through the traditional lossless compression method. Comparison shows that an
improved compression result is achieved.
