       grind - process WordNet lexicographer files


       grind  [  -v  ] [ -s ] [ -Llogfile ] [ -a ] [ -d ] [ -i ] [ -o ] [ -n ]
       filename [ filename... ]


       grind() processes WordNet lexicographer files, producing database files
       suitable  for  use with the WordNet search and interface code and other
       applications.  The syntactic and  structural  integrity  of  the  input
       files  is  verified.  Warnings and errors are reported via stderr and a
       run-time log is produced on stdout.  A database is  generated  only  if
       there are no errors.

   Input Files
       Input  files  correspond  to  the  syntactic  categories implemented in
       WordNet - noun, verb, adjective and adverb.  Each  input  lexicographer
       file  consists  of  a  list  of  synonym sets (synsets) for one part of
       speech.  Although the basic synset syntax is the same for  all  of  the
       parts  of  speech,  some parts of the syntax only apply to a particular
       part of speech.  See wninput(5WN) for a description of the  input  file

       Each filename specified is of the form:


       where  pathname  is  optional and pos is either noun, verb, adj or adv.
       suffix may be used to separate groups of synsets into different  files,
       for  example  noun.animal  and noun.plant.  One or more input files, in
       any  combination  of  syntactic  categories,  may  be  specified.   See
       lexnames(5WN)  for  a list of the lexicographer files used to build the
       complete WordNet database.

   Output Files
       grind() produces the following output files:

               | Filename   |              Description               |
               |index.pos   | Index file for each syntactic category |
               |data.pos    | Data file for each syntactic category  |
               |index.sense | Sense index                            |
       See wndb(5WN) for a description of the database file formats.

       Each time grind() is run, any existing database files  are  overwritten
       with  the  database files generated from the specified input files.  If
       no  input  files  from  a  syntactic  category   are   specified,   the
       corresponding database files are not overwritten.

   Sense Numbers
       Senses  are  generally ordered from most to least frequently used, with
       the most common sense numbered 1.  Frequency of use  is  determined  by
       the  number  of  times  a  sense  is  tagged  in  the  various semantic
       concordance texts.  Senses that are not semantically tagged follow  the
       ordered  senses in an arbitrary order.  Note that this ordering is only
       an estimate based on usage in a small corpus.

       The tagsense_cnt field for each entry in the index.pos files  indicates
       how many of the senses in the list have been tagged.

       The  cntlist  file provided with the database lists the number of times
       each sense is tagged in the semantic concordances.   grind()  uses  the
       data from cntlist to order the senses of each word.  When the index.pos
       files are generated, the synset_offsets  are  output  in  sense  number
       order,  with sense 1 first in the list.  Senses with the same number of
       semantic tags are assigned unique but consecutive sense  numbers.   The
       WordNet  OVERVIEW  search displays all senses of the specified word, in
       all syntactic  categories,  and  indicates  which  of  the  senses  are
       represented in the semantically tagged texts.


       -v             Verify integrity of input without generating database.

       -s             Suppress  generation of warning messages.  Usually grind
                      is  run  with  this  option  until  all  syntactic   and
                      structural   errors  are  corrected  since  the  warning
                      messages may make it difficult to spot error messages.

       -Llogfile      Write all messages to logfile instead of stderr.

       -a             Generate statistical report on input files processed.

       -d             Generate distribution of senses by string length  report
                      on input files processed.

       -i             Generate sense index file.

       -o             Order senses using cntlist.

       -n             Generate  nominalization (derivational morphology) links
                      in database.

       filename       Input file of the form described in Input Files.

       Exit  status  is  normally  0.  Exit status is -1 if non-specific error
       occurs.  If syntactic or structural errors exist, exit status is number
       of errors detected.
