Automatic Transformational Analysis and Generation with NooJ

Speaker:
Max Silberztein
Abstract:
NooJ is a linguistic development environment that allows linguists to formalize linguistic phenomena in the orthographical, morphological, syntactic and semantic levels, using a   range of linguistic resources: dictionaries, finite-state, context-free and context-sensitive  grammars. NooJ provides linguists with tools to edit, test and debug, maintain a large number of  linguistic resources, and can apply sets of resources (NooJ modules) to parse large corpora of  texts in real time. NooJ has been endorsed by the European Community and is now available as an  open source package, published on the Metashare Web Site. There are over 30 languages that are  being described with NooJ, see www.nooj4nlp.net.  In this presentation, I will describe the system that allows NooJ to perform transformational  analysis and generation, i.e. to produce any number of transformed sentences from one given  sentence. For instance, from the sentence 'Joe loves Mary', NooJ produces over 1.4 million  declarative sentences such as 'It is Joe who loves her', 'He is no longer in love with Mary'. The  system is reversible, i.e. NooJ can produce the analysis of complex sentences such as 'It is not Joe  who stopped to love her' in the form of a series of semantic features such as '+Declarative  +ExtractSubject, +Negation, +Aspect='Stop', +Preterit, +PronominalizeObject'.
