2.0to2.1.verb.poly - mapping from monosemous verb senses in WordNet
2.0 to corresponding 2.1 senses
WordNet users who have semantically
tagged text to senses in version 2.0, or who have statically assigned or
used 2.0 senses in other applications should upgrade to WordNet 2.1 if possible.
To help users automatically convert 2.0 noun and verb senses to their
corresponding 2.1 senses, we provide sense mapping information with version
2.1.
The sense mapping was done as follows:
·- Nouns and verbs unique to
either database were ignored.
·- Nouns and verbs that are monosemous in both
databases were found and their sense_key s and synset_offset s were mapped.
These sense mappings are in the files 2.0to2.1.{noun,verb}.mono .
·- All senses
of polysemous nouns and verb in version 2.0 were mapped to senses in version
2.1. Various heuristics were used to evaluate the similarity of 2.0 and
2.1 senses, and a score was assigned to each comparison. For each word,
each 2.0 sense was compared to all of the 2.1 senses for the same word,
and the 2.1 sense (or senses) with the highest score was deemed the best
mapping. These sense mappings are in the file 2.0to2.1.{noun,verb}.poly .
Heuristics include comparison of sense keys, similarity of synset terms,
and relative tree location (comparision of hypernyms). Glosses are not
used for comparisions, as they are often significantly modified.
A sense mapping is generally represented by two sense_key synset_offset
pairs, one for the 2.0 sense and one for its corresponding 2.1 sense. For
the polysemous sense mappings, sense_number is also in each pair. This
field is not needed in the monosemous mappings since all monosemous words
are assigned sense_number 1. See senseidx(5WN)
for a detailed description
of these fields.
In all the mapping files, a space is the field delimiter
unless otherwise noted, and each line is terminated with a newline character.
These files contain the mapping of sense keys for
nouns and verbs that are monosemous in both WordNet 2.0 and 2.1. Although
the actual words and sense numbers are the same in both databases, not
all sense_keys are the same, and the synset_offset s are different. This
file is an alphabetized list of one mapping per line. Each line is of
the form:
2.0_sense_key ; 2.0_synset_offset 2.1_sense_key ; 2.1_synset_offset
These files contain the mapping of sense keys
for nouns and verbs that are polysemous in WordNet 2.0 and are also found
in 2.1. This file is sorted by score from highest score (100) to lowest
(0), and then alphabetically within each score. Each line lists all 2.1
sense(s) that the corresponding 2.0 sense maps to with that score. Each
line is of the form:
score 2.0_sense_info 2.1_sense_info [2.1_sense_info...]
where sense_info consists of the following three fields:
sense_key
; synset_offset ; sense_number
Scores range from
0 to 100, and are an indication of how confident the mapping heuristics
are that the senses are the same - a higher score indicates greater reliability
in the mapping. The vast majority of senses mapped with a score of 90
or 100. Mappings with a score of 90 or greater make up 98% of the total
nouns senses mapped, and 97% of the total verb senses mapped.
There are 141,690 noun senses in WordNet 2.0. A total of 141,364 senses
have been mapped to senses in version 2.1. The remaining 326 senses represent
noun senses unique to version 2.0.
A total of 42,726 senses for polysemous
nouns are mapped in the file 2.0to2.1.noun.poly , with the following scores:
| Score | Count |
| 100 | 36992 |
| 90 | 5336 |
| 80 | 133 |
| 70 | 110 |

98,638 monosemous
nouns are mapped in the file 2.0to2.1.noun.mono .
There
are 24,632 verb senses in WordNet 2.0. A total of 24,617 senses have been
mapped to senses in version 2.1. The remaining 15 senses represent verb
senses unique to version 2.0.
A total of 18,546 senses for polysemous verbs
are mapped in the file 2.0to2.1.verb.poly , with the following scores:
| Score | Count |
| 100 | 17851 |
| 90 | 554 |
| 80 | 12 |
| 70 | 86 |
| 60 | 8

| 50 | 6 |
| 40 | 4 |
| 30 | 10 |
| 20 | 12 |
| 0 | 3 |
6,071 monosemous verbs
are mapped in the file 2.0to2.1.verb.mono .
The number of senses of
a polysemous word in version 2.0 often differs from the number of senses
for the same word in version 2.1. While there will always be a mapping
for each 2.0 sense to one or more 2.1 senses, there may be 2.1 senses to
which no 2.0 sense is mapped.
WordNet 2.0 words not found in either of the
monsemous maps are unique to version 2.0, and therefore cannot be mapped
to version 2.1.
