CNTLIST(5WN) WordNettm File Formats CNTLIST(5WN)NAME
cntlist - file listing number of times each tagged sense occurs in a semantic concordance, sorted most to least frequently tagged
cntlist.rev - file listing number of times each tagged sense occurs in a semantic concordance, sorted by sense key
DESCRIPTION
A cntlist file for a semantic concordance lists the number of times each semantically tagged sense occurs in the concordance and its sense
number in the WordNet database. Each line in the file corresponds to a sense in the WordNet database to which at least one semantic tag
points. Only senses that are tagged in a concordance are in the concordance's cntlist file.
WordNet Database cntlist File
In the WordNet database, words are assigned sense numbers based on frequency of use in semantically tagged corpora. The cntlist file used
by grind(1WN) to build the WordNet database and assign the sense numbers is a union of the cntlist files from the various semantic concor-
dances that were formerly released by Princeton University. This combined cntlist file is provided with the WordNet package and is found
in the WNSEARCHDIR directory.
The cntlist.rev file is used at run-time by the WordNet library code and browser interfaces to print in the output display the number of
times each sense has been tagged.
File Format
Each line in a cntlist file contains information for one sense. The file is ordered from most to least frequently tagged sense. The
fields are separated by one space, and each line is terminated with a newline character. Senses having the same tag_cnt value are listed
in reverse alphabetical order of the lemma field of the sense_key.
Each line in cntlist is of the form:
tag_cnt sense_key sense_number
where tag_cnt is the decimal number of times the sense is tagged in the corresponding semantic concordance. sense_key is a WordNet sense
encoding and sense_number is a WordNet sense number as described in
The cntlist.rev file contains the same fields described above, in the following order:
sense_key sense_number tag_cnt
NOTES
Princeton no longer maintains or releases the Semantic Concordance files. The cntlist file used to order the senses in WordNet 3.0 was
generated from the Semantic Concordance files at the point that they were last updated in 2001. In general, the order of senses presented
usually reflects what the user would expect, however sense ordering is now less reliable than in prior releases and should not be construed
as an accurate indicator of frequency of use.

index.sense, sense.idx - WordNet's sense index
DESCRIPTION
The WordNet sense index provides an alternate method for accessing synsets and word senses in the WordNet database. It is useful to appli-
cations that retrieve synsets or other information related to a specific sense in WordNet, rather than all the senses of a word or colloca-
tion. It can also be used with tools like grep and Perl to find all senses of a word in one or more parts of speech. A specific WordNet
sense, encoded as a sense_key, can be used as an index into this file to obtain its WordNet sense number, the database byte offset of the
synset containing the sense, and the number of times it has been tagged in the semantic concordance texts.
Concatenating the lemma and lex_sense fields of a semantically tagged word (represented in a <wf ... > attribute/value pair) in a semantic
concordance file, using % as the concatenation character, creates the sense_key for that sense, which can in turn be used to search the
sense index file.
A sense_key is the best way to represent a sense in semantic tagging or other systems that refer to WordNet senses. sense_keys are inde-
pendent of WordNet sense numbers and synset_offsets, which vary between versions of the database. Using the sense index and a sense_key,
the corresponding synset (via the synset_offset) and WordNet sense number can easily be obtained. A mapping from noun sense_keys in Word-
Net 1.6 to corresponding 2.0 sense_keys is provided with version 2.0, and is described in sensemap(5WN).
See wndb(5WN) for a thorough discussion of the WordNet database files.
File Format
The sense index file lists all of the senses in the WordNet database with each line representing one sense. The file is in alphabetical
order, fields are separated by one space, and each line is terminated with a newline character.
Each line is of the form:
sense_key synset_offset sense_number tag_cnt
sense_key is an encoding of the word sense. Programs can construct a sense key in this format and use it as a binary search key into the
sense index file. The format of a sense_key is described below.
synset_offset is the byte offset that the synset containing the sense is found at in the database "data" file corresponding to the part of
speech encoded in the sense_key. synset_offset is an 8 digit, zero-filled decimal integer, and can be used with fseek(3) to read a synset
from the data file. When passed to the WordNet library function read_synset() along with the syntactic category, a data structure contain-
ing the parsed synset is returned.
sense_number is a decimal integer indicating the sense number of the word, within the part of speech encoded in sense_key, in the WordNet
database. See wndb(5WN) for information about how sense numbers are assigned.
tag_cnt represents the decimal number of times the sense is tagged in various semantic concordance texts. A tag_cnt of 0 indicates that
the sense has not been semantically tagged.
Sense Key Encoding
A sense_key is represented as:
lemma%lex_sense
where lex_sense is encoded as:
ss_type:lex_filenum:lex_id:head_word:head_id
lemma is the ASCII text of the word or collocation as found in the WordNet database index file corresponding to pos. lemma is in lower
case, and collocations are formed by joining individual words with an underscore (_) character.
ss_type is a one digit decimal integer representing the synset type for the sense. See Synset Type below for a listing of the numbers cor-
responding to each synset type.
lex_filenum is a two digit decimal integer representing the name of the lexicographer file containing the synset for the sense. See lex-
names(5WN) for the list of lexicographer file names and their corresponding numbers.
lex_id is a two digit decimal integer that, when appended onto lemma, uniquely identifies a sense within a lexicographer file. lex_id num-
bers usually start with 00, and are incremented as additional senses of the word are added to the same file, although there is no require-
ment that the numbers be consecutive or begin with 00. Note that a value of 00 is the default, and therefore is not present in lexicogra-
pher files. Only non-default lex_id values must be explicitly assigned in lexicographer files. See wninput(5WN) for information on the
format of lexicographer files.
head_word is only present if the sense is in an adjective satellite synset. It is the lemma of the first word of the satellite's head
synset.
head_id is a two digit decimal integer that, when appended onto head_word, uniquely identifies the sense of head_word within a lexicogra-
pher file, as described for lex_id. There is a value in this field only if head_word is present.
Synset Type
The synset type is encoded as follows:
1 NOUN
2 VERB
3 ADJECTIVE
4 ADVERB
5 ADJECTIVE SATELLITE
NOTES
For non-satellite senses the head_word and head_id fields have no values, however the field separator character (:) is present.
