Revision history for Perl extension Lingua::Wordnet.

0.01 Mon May 17 10:58:40 1999

• original version; created by h2xs 1.19

0.1 Mon Feb 2 1:28:30 2000

• rewrote whole module to convert dbs to Berkeley DB files
• took out all Wordnet C API code

0.2 Fri Apr 14 11:24:30 2000

• added pointer counting to 'scripts/report.pl'
• fixed examples for Lingua::Wordnet::Analysis::intersection() to use references
• added Lingua::Wordnet::Analysis::distance()
• changed Wordnet.pm and scripts/convertdb.pl to allow custom data delimiters via the $DELIM and $SUBDELIM globals.
• made nested subs in Analysis.pm anonymous, thanks to Josef Meyer
• fixed lookup_synsets morphing, thanks to Melissa L. Holcombe
• changed morph() to require a POS, and convertdb.pl writes the morph database with POS labels.

0.3 Sun Apr 16 3:24:12 2000

• lots of POD edits
• improved (fixed) lots of add/delete pointer functions
• fixed Lingua::Wordnet::Analysis::match()

0.4 Thu Aug 24 11:36:14 2000

• fixed installation to recommend a 'cd' to convert the dbs
• removed plan to automate the synchronization of corrsponding pointer types
• more POD updates and typos
• added a small 'wn.pl' script to 'scripts/' to illustrate the most basic usage

0.5 Thu Aug 31 20:07:54 2000

• added 'overview' method due to popular demand
• overloaded stringify operators ("") for class Lingua::Wordnet::Synset; you can print '$synset' directly and get an overview for the synset; it uses 'overview()'
• added test of overloaded behavior

0.6 Tue Oct 17 2000

• Changed the overload syntax in Wordnet.pm (line 559) to work for Perl < 5.6.
• Fixed some typos in 'scripts/10questions.pl'

0.65 Wed Feb 21 2001

• Fixed documentation errors
• Added reverse_morph() lookups (don't use them)
• Fixed errors in new_synset()

0.7 Wed Mar 7 2001

• Data file formats have changed in 0.7. This requires new conversion using the 'scripts/convertdb.pl' script. What hasn't changed is the way any of the indexes are written, so this should not affect most code. What has changed is the way each word entry is written to the data files. Word entries are now of the form "lemma%sense_num", where sense_num is the unique number for the sense of lemma in a POS (rather than unique within a lexicographer file). This makes the return values for words conform to what you might expect to see when searching for a given sense.
  • Added lookup_synset_all()
  • Added scripts/big_struct.pl
  • Added scripts/tree.pl
  • Fixed the lemma% concatenation, which misrepresented the sense numbers
  • Changed 'scripts/convertdb.pl' to try harder to update paths in Wordnet.pm

0.71 Mon Aug 13 2001

• This release is compatible with Wordnet 1.7, but requires a rebuild of the data files. Wordnet 1.7 changes include new file byte offsets; these do not map to 1.6 offsets, and this module performs no conversion (no access to the "Sense Map" package). Additionally, some sense numbers have changed.

  This release should still be compatible with 1.6, but includes no features that enhance 1.6.

  • 1.7 does not have a "cousin.exc" list; caused the conversion script to not choke as a result.
  • Added a script 'scripts/convertdb_win.pl' for Win32 compatibility; thanks to Ray Schumacher.
  • Changed test.pl to work with new synset numbers

0.72 Mon Dec 17 2001

• Fixed test.pl ... again ... to work with new synset numbers

0.73 Tue Dec 18 2001

• Changes synset write() behaviour to store offsets correctly, and changed Lingua::Wordnet typos. Thanks Marco Nova.

0.74 Wed Aug 11 2004

• Fixed tests for Wordnet 2.0
• Significant updates thanks to Markus Koppenberger and his group at Universidad Pompeu Fabra:
  • Wordnet.pm
    • morph() now returns an array (it's possible that a word has more than one baseform
    • reverse_morph() does the same ...
    • lookup_synset returns the synsets for all forms of morph
    • the 'functions' are commented now, because WN 2.0 uses the '+' pointer for derivational morphology
    • added functions for domains and domainterms (all_domains, category_domains, region_domains, usage_domains and all_domainterms, category_domainterms, region_domainterms, usage_domainterms). there are also example 2 scripts for that functions
  • convertdb.pl
    • some code-cleanup: added -w and 'use strict', Removed some global variables and corrected some typos. Added some comments.
    • loops over all pos-types (index.<pos>, <pos>.exc and data.<pos>
    • changed structure of lingua_wordnet.morph:if there are more than one baseform, the value of the morph-hash will contain both seperated by $DELIM
  • Analysis.pm
    • added a function 'global_distance', which tries to find the steps needed from one to another synset. (highly experimental, very slow)
  • scripts/
    • added scripts to show the new functionalities

      TODO

• find someone to maintain the module
• methods for XML delivery of data
