Conversational language comprehension using integrated pattern-matching and parsing

• Roger C. Parkinson

One of the major problems in natural language understanding by computer is the frequent use of patterned or idiomatic phrases in colloquial English dialogue. Traditional parsing methods typically cannot cope with a significant number of idioms. A more general problem is the tendency of a speaker to leave the meaning of an utterance ambiguous or partially implicit, to be filled in by the hearer from a shared mental context which includes linguistic, social, and physical knowledge. The appropriate representation for this knowledge is a formidable and unsolved problem. We present here an approach to natural language understanding which addresses itself to these problems. Our program uses a series of processing stages which progressively transform an English input into a form usable by our computer simulation of paranoia. Most of the processing stages involve matching the input to an appropriate stored pattern and performing the associated transformation. However, a few key stages perform aspects of traditional parsing which greatly facilitate the overall language recognition process.

Turing-like indistinguishability tests for the validation of a computer simulation of paranoid processes

A computer simulation of paranoid processes in the form of a dialogue algorithm was subjected to a validation study using indistinguishability tests. Judges rated degrees of paranoia present in initial psychiatric interviews of both paranoid patients and of versions of the paranoid model. Judges also attempted to distinguish teletyped interviews with real patients from interviews with the simulation model. The statistical results indicate a satisfactory degree of resemblance between the two groups of interviews. It is concluded that the model provides a successful simulation of naturally occurring paranoid processes as measured by these tests.

Artificial Paranoia

• Kenneth Mark Colby
• Sylvia Weber
• Franklin Dennis Hilf

A case of artificial paranoid has been synthesized in the form of a computer simulation model. The model and its embodied theory are briefly described. Several excerpts from interviews with the model are presented to illustrate its paranoid input-output behavior. Evaluation of the success of the simulation will depend upon indistinguishability tests.
