       index.adv, data.adv - WordNet database files

       noun.exc, verb.exc. adj.exc adv.exc - morphology exception lists

       sentidx.vrb, sents.vrb - files used by search code to display sentences
       illustrating the use of some specific verbs

DESCRIPTION
       For each syntactic category, two files are needed to represent the con-
       tents of the WordNet database - index.pos and data.pos,  where  pos  is
       noun,  verb,  adj  and  adv.  The other auxiliary files are used by the
       WordNet library's searching functions and are needed to run the various
       WordNet browsers.

       Each index file is an alphabetized list of all the words found in Word-
       Net in the corresponding part of speech.  On each line,  following  the
       word,  is  a list of byte offsets (synset_offsets) in the corresponding
       data file, one for each synset containing the word.  Words in the index
       file are in lower case only, regardless of how they were entered in the
       lexicographer files.  This folds various  orthographic  representations
       of  the word into one line enabling database searches to be case insen-
       sitive.  See wninput(5WN) for a detailed description of the  lexicogra-
       pher files

       A data file for a syntactic category contains information corresponding
       to the synsets that were specified in  the  lexicographer  files,  with
       relational  pointers resolved to synset_offsets.  Each line corresponds
       to a synset.  Pointers are followed and hierarchies traversed by moving
       from one synset to another via the synset_offsets.

       The  exception  list files, pos.exc, are used to help the morphological
       processor find base forms from irregular inflections.

       The files sentidx.vrb and sents.vrb contain sentences illustrating  the
       use  of  specific  senses  of  some verbs.  These files are used by the
       searching software in response to a request for verb  sentence  frames.
       Generic  sentence frames are displayed when an illustrative sentence is
       not present.

       The various database files are in ASCII formats that are easily read by
       both humans and machines.  All fields, unless otherwise noted, are sep-
       arated by one space character, and all lines are terminated by  a  new-
       line  character.  Fields enclosed in italicized square brackets may not
       be present.

       See wngloss(7WN) for a glossary of WordNet terminology and a discussion
       of the database's content and logical organization.

   Index File Format
       Each  index  file  begins  with  several  lines  containing a copyright
       notice, version number and license agreement.  These  lines  all  begin
       with  two  spaces and the line number so they do not interfere with the
       binary search algorithm that is used to look up entries  in  the  index
       files.   All  other  lines  are  in the following format.  In the field


       All remaining fields are with respect to senses of lemma in pos.


       synset_cnt     Number of synsets that lemma is in.  This is the  number
                      of  senses  of  the  word  in WordNet. See Sense Numbers
                      below for a discussion of how sense numbers are assigned
                      and the order of synset_offsets in the index files.

       p_cnt          Number  of  different  pointers  that  lemma  has in all
                      synsets containing it.

       ptr_symbol     A space separated  list  of  p_cnt  different  types  of
                      pointers  that  lemma  has in all synsets containing it.
                      See wninput(5WN) for a list of pointer_symbols.  If  all
                      senses  of lemma have no pointers, this field is omitted
                      and p_cnt is 0.

       sense_cnt      Same as sense_cnt above.  This  is  redundant,  but  the
                      field was preserved for compatibility reasons.

       tagsense_cnt   Number  of  senses of lemma that are ranked according to
                      their frequency of occurrence  in  semantic  concordance
                      texts.

       synset_offset  Byte  offset  in  data.pos  file  of a synset containing
                      lemma.  Each synset_offset in the list corresponds to  a
                      different  sense  of lemma in WordNet.  synset_offset is
                      an 8 digit, zero-filled decimal integer that can be used
                      with fseek(3) to read a synset from the data file.  When
                      passed to read_synset(3WN) along with the syntactic cat-
                      egory,  a data structure containing the parsed synset is
                      returned.

   Data File Format
       Each data file begins with several lines containing a copyright notice,
       version  number  and license agreement.  These lines all begin with two
       spaces and the line number.  All other lines are in the following  for-
       mat.  Integer fields are of fixed length, and are zero-filled.

       synset_offset  lex_filenum  ss_type  w_cnt  word  lex_id  [word  lex_id...]  p_cnt  [ptr...]  [frames...]  |  gloss


       synset_offset  Current  byte  offset  in  the  file represented as an 8
                      digit decimal integer.

       lex_filenum    Two digit decimal integer corresponding to the  lexicog-
                      rapher  file  name  containing  the  synset.   See  lex-
                      names(5WN) for the list of filenames  and  their  corre-
                      sponding numbers.

       ss_type        One character code indicating the synset type:

                      contrast  to  its  form  in  the corresponding index.pos
                      file, that contains only lower-case forms.  In data.adj,
                      a  word  is  followed  by  a syntactic marker if one was
                      specified in the lexicographer file.  A syntactic marker
                      is  appended,  in  parentheses,  onto  word  without any
                      intervening spaces.  See wninput(5WN) for a list of  the
                      syntactic markers for adjectives.

       lex_id         One  digit  hexadecimal integer that, when appended onto
                      lemma, uniquely identifies a sense within  a  lexicogra-
                      pher file.  lex_id numbers usually start with 0, and are
                      incremented as additional senses of the word  are  added
                      to  the same file, although there is no requirement that
                      the numbers be consecutive or begin with 0.  Note that a
                      value  of 0 is the default, and therefore is not present
                      in lexicographer files.

       p_cnt          Three digit decimal integer  indicating  the  number  of
                      pointers from this synset to other synsets.  If p_cnt is
                      000 the synset has no pointers.

       ptr            A pointer from this synset to another.  ptr  is  of  the
                      form:

                      pointer_symbol  synset_offset  pos  source/target

                      where  synset_offset  is  the  byte offset of the target
                      synset in the data file corresponding to pos.

                      The source/target field distinguishes lexical and seman-
                      tic  pointers.   It is a four byte field, containing two
                      two-digit hexadecimal integers.  The  first  two  digits
                      indicates  the  word  number  in  the  current  (source)
                      synset, the last two digits indicate the word number  in
                      the   target   synset.   A  value  of  0000  means  that
                      pointer_symbol represents a  semantic  relation  between
                      the  current (source) synset and the target synset indi-
                      cated by synset_offset.

                      A  lexical  relation  between  two  words  in  different
                      synsets  is represented by non-zero values in the source
                      and target word numbers.  The first and last  two  bytes
                      of  this  field  indicate the word numbers in the source
                      and target  synsets,  respectively,  between  which  the
                      relation  holds.   Word numbers are assigned to the word
                      fields in a synset, from left to right,  beginning  with
                      1.

                      See  wninput(5WN)  for  a  list  of pointer_symbols, and
                      semantic and lexical pointer classifications.

       frames         In data.verb only, a list of  numbers  corresponding  to
                      the  generic  verb  sentence  frames  for  words  in the
                      synset.  frames is of the form:
                      See  wninput(5WN)  for  the text of the generic sentence
                      frames.

       gloss          Each synset contains a gloss.  A gloss is represented as
                      a  vertical bar (|), followed by a text string that con-
                      tinues until the end of the line.  The gloss may contain
                      a definition, one or more example sentences, or both.

   Sense Numbers
       Senses  in  WordNet 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.  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(5WN)  file  provided with the database lists the number of
       times each sense is tagged in the semantic concordances.  The data from
       cntlist  is  used by grind(1WN) 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 speci-
       fied word, in all syntactic categories,  and  indicates  which  of  the
       senses are represented in the semantically tagged texts.

   Exception List File Format
       Exception  lists are alphabetized lists of inflected forms of words and
       their base forms.  The first field of each line is an  inflected  form,
       followed  by  a  space  separated list of one or more base forms of the
       word.  There is one exception list file for each syntactic category.

       Note that the noun and verb exception lists were  automatically  gener-
       ated  from  a  machine-readable dictionary, and contain many words that
       are not in WordNet.  Also, for many of the inflected forms, base  forms
       could  be  easily  derived  using the standard rules of detachment pro-
       grammed into Morphy (See morph(7WN)).  These anomalies are  allowed  to
       remain in the exception list files, as they do no harm.


   Verb Example Sentences
       For  some  verb  senses,  example sentences illustrating the use of the
       verb sense can be displayed.  Each line of the  file  sentidx.vrb  con-
       tains  a  sense_key  followed  by a space and a comma separated list of
       example sentence template numbers,  in  decimal.   The  file  sents.vrb
       lists all of the example sentence templates.  Each line begins with the
       template number followed by a space.  The rest of the line is the  text
       of  a  template  example sentence, with %s used as a placeholder in the
       text for the verb.  Both files are sorted alphabetically  so  that  the
       sense_key and template sentence number can be used as indices, via bin-
       srch(3WN), into the appropriate file.

       When a request for FRAMES is made, the WordNet search  code  looks  for
       tic category (since it is possible for synsets  in  different  data.pos
       files to have the same synset_offset).

       The  WordNet  system provide both command line and window-based browser
       interfaces to the database.  Both interfaces utilize a  common  library
       of  search  and  morphology  code.  The source code for the library and
       interfaces is included in the WordNet package.  See wnintro(3WN) for an
       overview of the WordNet source code.
