  1. NL-Soar update Deryle Lonsdale BYU Linguistics lonz@byu.edu Soar 2003

  2. BYU Soar Research Group • 1 faculty, 6-10 students/year • Weekly meetings • Literature, development, planning • Goals: • Expand Soar knowledge and explore possible uses on-campus • Provide and support an NL capability to the Soar research community • Toolkits, resources, knowledge repositories • Carry out research into the cognitive modeling of linguistic performance Soar 2003

  3. NL-Soar (overview) • Soar for natural-language modeling • Comprehension (NLC) • Parsing sentences into syntax/semantics • Discourse (NLD) • Discourse moves, turns, participants • Generation (NLG) • Tactical sentence generation • Various language-related applications • Parsing, acquisition, translation, task integration Soar 2003

  4. What we’ve accomplished • Several students have learned to use NL-Soar (and some even write sp’s) • Substantial improvements to coverage • Still a lot remains, though... • Testing (including the patience of those who want to use it...) • Bug tracking via in-house version of SourceForge • LG-Soar (Data Extraction RG) Soar 2003

  5. What we’ve accomplished (2) • Updated website (biblio, mini-tutorials) • Two-agent conversation over sockets • Involves NLC, NLD, NLG • Workable solution(s) to massive ambiguity problems due to WordNet • Tutorial at this workshop Soar 2003

  6. The new release (2003) • Soar 7.3, Tcl 8.x, WordNet 1.6 • Some new documentation • Hasn’t gone out yet... • What’s the best vehicle? • Works pretty well, though semantics coverage needs to be increased Soar 2003

  7. What we’ll be working on • Increasing linguistic coverage • Including an interface to morphology engine • Releasing and documenting new release • Chunking/learning (including WSD) • WordNet 1.6  1.7.1 • Soar 8.x (works already, but...) • More interesting conversational discourse • Other languages (French) • Integration with other NLP tools • Other lexicons (e.g. CELEX) • Other grapher (CLIG) Soar 2003

  8. Complete linguistics coverage is hard It’ll be a difficult transition from in-house The NLP pendulum is not currently favorable We’re a strictly volunteer team again We’re doing real language (and gaining associated insights) The architecture still works (and we’re still trying to listen...) Less ad-hoc, more principled development Interest is picking up Coals Nuggets Soar 2003
