The PS file has been generated by dvips, the default TeX PostScript 
generation method. This method, by default, positions each character 
indifidually, therefore there is no trivial method to extract text from it; 
it requires more intelligent algorithms (e.g. to compare the distance 
between rendered characters with the normal interword spacing to determine 
word boundaries etc.
