grind - process WordNet lexicographer files

       Please report bugs to wordnet@princeton.edu.

WordNet 3.0                                         Dec 2006                                            GRIND(1)

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.

   InputFiles
       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
       format.

       Each filename specified is of the form:

              pathname/pos.suffix

       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.

   OutputFilesgrind() 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.

   SenseNumbers
       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.

       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.

              None of the filenames specified were of the appropriate form.

              Syntax errors were found while parsing the input files.

       grind - process WordNet lexicographer files

-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 InputFiles.
