TITLE
     
     A system of morphological analysis of Russian word-forms
     
     
OBJECTIVES
     
     The system takes as its input a Russian text or  a  word.
For each  word  of  a text  all the homonymous versions of its
morphological analysis  are  considered.   At  the  output  an
array(a stream)  of records(structures)  is formed, one record
per each homonym of each input word and per  each  punctuation
mark. Such  a  record  contains a unique number of a lexeme (a
dictionary entry),  which is appointed for  it  and  does  not
change with  enlargement  of  the  dictionary,   and  a set of
grammatical characteristics of a word such as the  case,   the
gender, the number etc.
     
     One  may  regard  as  a special feature of the system the
fact that, apart from the morphological analysis proper  (i.e.
inflectional  analysis),  each word is examined from the point
of view of occasional word-derivation. Moreover, for each word
among its homonymous versions are given some hypotheses on its
possible erroneous use, which sharply raises  the  possibility
of  understanding  a  sentence with the subsequent syntactical
analysis in the case of  erroneous  agreement  of  words.  The
latter  peculiarity  of  the  system  may turn out helpful for
persons with an incomplete command of the Russian language.
     
      The system  is equiped with a dictionary compilid on the
basis of "Grammatical Dictionary of Russian" bu A.A.Zaliznjak
and containing about 100 thousand words.
     
     The utilization  of the elements of derivational analysis
in the algorithm made it possible  to  reduce  the  dictionary
information to  the  capacity  stored in the main memory up to
640K, which  ensures  (a)   high  internal  performance,   (b)
possibility of using a computer without a hard disk.
     

APPLICATIONS
     
     Liguistic processors and artificial intelligence systems,
text processing systems, automatic translation systems.

     The system can be  utilized  both  independently  and  in
combination with a syntactical analysis module at our disposal
or of your own.
