TITLE
     
     A language-independent shell of a system
     of precise morphological analysis and
     synthesis of natural language texts and

     a functioning system of this type for the
     Russian language
     
OBJECTIVES
     
     
     The shell  must be adjusted to a specific language by (a)
filling in  linguistic  tables  which  contain  data  on  this
lahguage and  (b)   compiling  a dictionary where words of the
language are assigned reference to corresponding lines of  the
tables. All  linguistic resources of the system(recognition of
some forms,  error correction etc.)  are determined only by  a
form of tables and may be brought into perfect conformity with
your own views and needs.  An example of filling in tables for
the Russian language is given.
     
     A  system constructed in this way represents a library of
routines with the following functions: (a) INPUT: a text or  a
word,  OUTPUT:  for  each word of the text - its unique number
which  remains  invariable  with  any  modification   of   the
dictionary  and a set of its grammatical characteristics (such
as the case, the number, the tense and so on); (b) the reverse
transformation - generation of a word on the basis of a set of
characteristics; (c) correction of mis-spelt  words  with  the
possibility of explaining the gist of an error; (d) generation
of a given form (or the dictionary form) of a word; etc.
     
     Special features:   extensibility  for  enlargement   and
gradual accumulation of linguistic knowledges; differentiation
of homonymy and variability:  appointment of a  unique  number
for a word; recognition and correction of mis-spelt words; the
possibility of  entering  in  the  dictionary  of  those  word
strings which contain non-letter symbols and spaces as well as
of some word combinations; high internal  performance  at  the
expence of the original access to the dictionary.
     
APPLICATIONS
     
     Linguistic processor and artificial intelligence systems,
text processing  systems,   text   well-formedness   checking,
teaching systems,     translation   systems   and   electronic
dictionaries, linguistic researches and compiling of frequency
dictionaries. The  system  may  be  used  by  persons  with an
incomplete command of Russian.
     
     It is  particularly  efficient  when  combined   with   a
syntactical analysis module at our disposal or of your own.
