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
