  1. OntoSoar: Feeding a Growing Ontology CS 652 Information Extraction and Integration Fall 2012 Peter Lindes OntoSoar

  2. Project Goals • Use linguistic technologies to: • Find more facts • Learn new categories and relations • Technologies to be used: • OntoES • Link Grammar Parser • LG-Soar • Soar • Discourse Representation Theory OntoSoar

  3. What is OntoES? • A system for building OSM models • Capable of representing extraction ontologies • Processes text to extract facts OntoSoar

  5. OntoSoar

  6. What is Soar? • A cognitive architecture • A system that implements that architecture • Major elements: • Short- and long-term memories • Decision procedure • Perception and action modules • Various kinds of learning • Example applications: • TacAirSoar • BOLT Project OntoSoar

  18. Processing Steps • Gather section of text • Segment into sentence fragments • Parse with the LG-Parser • Build predicates with LG-Soar • Resolve pronouns using DRT • Convert predicates to facts • Match extracted facts against conceptual model • Record facts that match • Learn from partial matches OntoSoar
