This library is a Ruby interface to WordNet®[https://wordnet.princeton.edu/]. WordNet® is an online lexical reference system whose design is inspired by current psycholinguistic theories of human lexical memory. English nouns, verbs, adjectives and adverbs are organized into synonym sets, each representing one underlying lexical concept. Different relations link the synonym sets.
This library uses SqlUNET[http://sqlunet.sourceforge.net/], which is a conversion of the WordNet (along with a number of other linguistic databases) lexicon flatfiles into a relational database format. You can either install the wordnet-defaultdb gem, which packages up the SQLite3 version of SqlUNet, or install your own and point the lexicon at it by passing Sequel connection parameters to the constructor.
There are three major parts to this library:
WordNet::Lexicon : the interface to the dictionary, used to connect to the database and look up Words and Synsets.
WordNet::Word : the English word entries in the Lexicon that are mapped to Synsets via one or more Senses.
WordNet::Synset : the main artifact of WordNet: a "synonym set". These : are connected to one or more Words through a Sense, and are connected to each other via SemanticLinks.
The other object classes exist mostly as a way of representing relationships between the main three:
WordNet::Sense : represents a link between one or more Words and one or more Synsets for one meaning of the word.
WordNet::SemanticLink : represents a link between Synsets
WordNet::LexicalLink : represents a link between Words in Synsets
WordNet::Morph : an interface to a lookup table of irregular word forms mapped to their base form (lemma)
The last class (WordNet::Model) is the abstract superclass for all the others, and inherits most of its functionality from Sequel::Model, the ORM layer of the Sequel toolkit. It's mostly just a container for the database connection, with some convenience methods to allow the database connection to be deferred until runtime instead of when the library loads.
The library also comes with the beginnings of support for the SUMO-WordNet mapping:
WordNet::SumoTerm : Suggested Upper Merged Ontology terms, with associations back to related Synsets.
As mentioned above, SqlUNet has done an amazing job of linking up a number of other useful linguistic lexicons via WordNet synsets. I plan on adding support for at minimum VerbNet, FrameNet, and PropBank.
- Ruby >= 3.0
- Sequel >= 5.0
You can check out the current development source with Mercurial via its project page. Or if you prefer Git, via its Github mirror.
After checking out the source, run:
$ gem install -Ng
$ rake setup
This will do any necessary development environment set up.
