Homer: Text Interpreter

Description

• Parser and semantic interpreter operate bottom-up, yielding all semantically meaningful interpretations
• Parsing and interpretation interleaved, so meaningless parse trees are eliminated from consideration
• Interpreter runs asynchronously, so parsing and interpretation begin as a sentence is being typed in
• Natural language sentences translated into state transition representation
  • Provides flexible, powerful method for representing action verbs: framelike descriptions are augmented by descriptions of effect on world state
  • Small set of primitive relations (i.e. CONNECTED, ISA, IN, SHAPE) describe the world and may be composed to form complex meanings
• This method is believed to be required for an agent who must plan using information transmitted via natural language
