Abstract

Abstract A parsing method and apparatus for symbolic expressions of thought such as English-language sentences is provided. The basic procedure distinguishes only between symbols for picture-like entities (such as "squirrel" or "justice") and symbols for relations (such as "above" or "pushed"). For example, to the cognitive parser the sentences "The squirrel buried a nut" and "My aunts sent a telegram" are equivalent. The parser thus operates at a level more basic than syntactic parsing, making it simpler. The illustrative embodiment, a cognitive parser for English sentences, comprises: a microprocessor, a stored lexicon including symbols and associated entity-types (picture or relation), an input device for a symbol sequence, and a procedure executing on the microprocessor for grouping the inputted picture-designating and relation-designating symbols according to rules based on entity type. A method comprising operation of the cognitive parser is also provided.

Claim 3
Dependent Claim 12 words
The apparatus of claim 1, wherein said input device comprises a keyboard.
Claim 4
Dependent Claim 13 words
The apparatus of claim 1, wherein said input device comprises a voice-recognition system.

Claim 6
Dependent Claim 18 words
The apparatus of claim 1, wherein said output device comprises a software program for using the symbol grouping.
Claim 7
Dependent Claim 16 words
The apparatus of claim 5, wherein said software program operates a control unit of another device.
Claim 8
Dependent Claim 14 words
The apparatus of claim 1, wherein said output device comprises an information storage device.
Claim 9
Dependent Claim 58 words
The apparatus of claim 1, wherein said lexicon includes a cognitive category valuation for each symbol that designates a picture-like entity, the cognitive category substantially ranging from sensation-related to abstract concepts; and wherein said program includes a consecutive picture-symbol routine that uses the cognitive category valuation for inserting a relation-designating symbol between consecutive symbols which designate picture-like entities.
Claim 10
Dependent Claim 46 words
The apparatus of claim 1, wherein said procedure includes routines selected from the group consisting of a picture-symbol grouping routine, a hierarchy-building routine, and a track-utilization routine; and wherein said procedure uses said routines for building a symbol group consisting of picture-designating symbols and relation-designating symbols.
Claim 11
Dependent Claim 51 words
The apparatus of claim 1, wherein said lexicon includes symbol-grouping properties corresponding to at least some of the symbols; and wherein said procedure also determines the symbol-grouping properties corresponding to an inputted symbol and also groups the inputted picture-designating and relation-designating symbols into a symbol group according to the symbol-grouping properties.
Claim 12
Dependent Claim 65 words
A lexicon for use in a parser for symbol sequences such as natural language sentences comprising: a memory device; and a table, stored in said memory device, including a plurality of symbols and an entity-type corresponding to each symbol of the plurality of symbols, the entity-type selected from the group consisting of a picture-like entity, a relation, and a picture-like entity accompanied by a relation.
Claim 13
Dependent Claim 65 words
A lexicon for use in a parser for symbol sequences such as natural language sentences comprising: a memory device; and a table, stored in said memory device, including a plurality of symbols and an entity-type corresponding to each symbol of the plurality of symbols, the entity-type selected from the group consisting of a picture-like entity, a relation, and a picture-like entity accompanied by a relation.
Claim 14
Dependent Claim 38 words
The lexicon of claim 11, wherein said table further comprises a cognitive category valuation for each symbol of the plurality of symbols which designates a picture-like entity, the cognitive category valuation substantially ranging from sensation-related to abstract concepts.
Claim 15
Dependent Claim 35 words
The lexicon of claim 11, wherein said table further comprises symbol-grouping properties associated with at least one of the plurality of symbols, said symbol-grouping properties applying to picture-designating and relation-designating symbols of said symbol sequences.
Claim 16
