1.7.1 to corresponding 2.0 senses
WordNet users who have semantically
tagged text to senses in version 1.7.1, or who have statically assigned
or used 1.7.1 senses in other applications should upgrade to WordNet 2.0
if possible. To help users automatically convert 1.7.1 noun and verb senses
to their corresponding 2.0 senses, we provide sense mapping information
with version 2.0.
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 1.7.1to2.0.{noun,verb}.mono
.
·- All senses of polysemous nouns and verb in version 1.7.1 were mapped to
senses in version 2.0. Various heuristics were used to evaluate the similarity
of 1.7.1 and 2.0 senses, and a score was assigned to each comparison. For
each word, each 1.7.1 sense was compared to all of the 2.0 senses for the
same word, and the 2.0 sense (or senses) with the highest score was deemed
the best mapping. These sense mappings are in the file 1.7.1to2.0.{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 1.7.1 sense and one for its corresponding 2.0 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 1.7.1 and 2.0. 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:
1.7.1_sense_key ; 1.7.1_synset_offset 2.0_sense_key ; 2.0_synset_offset
These files contain the mapping of sense keys
for nouns and verbs that are polysemous in WordNet 1.7.1 and are also found
in 2.0. This file is sorted by score from highest score (100) to lowest
(0), and then alphabetically within each score. Each line lists all 2.0
sense(s) that the corresponding 1.7.1 sense maps to with that score. Each
line is of the form:
score 1.7.1_sense_info 2.0_sense_info [2.0_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 134,716 noun senses in WordNet 1.7.1. A total of 134,345 senses
have been mapped to senses in version 2.0. The remaining 371 senses represent
noun senses unique to version 1.7.1.
A total of 40,562 senses for polysemous
nouns are mapped in the file 1.7.1to2.0.noun.poly , with the following scores:
| Score | Count |
| 100 | 37895 |
| 90 | 2247 |
| 80 | 132 |

93,783 monosemous
nouns are mapped in the file 1.7.1to2.0.noun.mono .
There
are 24,169 verb senses in WordNet 1.7.1. A total of 24,107 senses have been
mapped to senses in version 2.0. The remaining 61 senses represent verb
senses unique to version 1.7.1.
A total of 18,283 senses for polysemous
verbs are mapped in the file 1.7.1to2.0.verb.poly , with the following scores:
| Score | Count |
| 100 | 15914 |
| 90 | 1900 |
| 80 | 54 |
| 70 | 182 |

5,824 monosemous
verbs are mapped in the file 1.7.1to2.0.verb.mono .
The number of senses
of a polysemous word in version 1.7.1 often differs from the number of senses
for the same word in version 2.0. While there will always be a mapping
for each 1.7.1 sense to one or more 2.0 senses, there may be 2.0 senses to
which no 1.7.1 sense is mapped.
WordNet 1.7.1 words not found in either of
the monsemous maps are unique to version 1.7.1, and therefore cannot be
mapped to version 2.0.
