<DIV><FONT size=2 face=Arial>Dear colleahues, usually it is possible to find out
if two texts are different if some certain linguistic units are used there with
different frequencies. Is it possible to differentiate two texts basing on the
frequency of occurrence of preposions: on, in, at, under, over, etc. Has many
articles been published on the use of prepositions as features? Looking forward
to hearing from you to <A href="mailto:yutamb@mail.ru">yutamb@mail.ru</A>
Yours sincerely Yuri Tambovtsev, Novosibirsk, Russia</FONT></DIV></BODY></HTML>
