Abstract

A method of syntactically categorizing the constituents of English language sentences and a schema for depicting all possible categories to which the constituents of any sentence could belong. It also depicts the general order to appearance of the basic elements (foundation elements) in a sentence and their alignment according to the functions they perform in a sentence, the alignment being informative to a schema user of certain relationships between constituents of a common function. In one embodiment of the schema, all possible forms and functions of foundation elements are depicted in a plurality of adjacent rows, all rows being parallel to an ordinate, each row containing only foundation elements of a common form in the general order of their common use in a sentence, the number of rows corresponding to the number of forms of foundation elements; all possible forms and functions of modifying elements are depicted in a plurality of adjacent rows, all parallel to said ordinate, each row being ordered to correspond to the foundation elements which they modify, and each row containing only modifying elements of a common form, the number of rows corresponding to the number of forms of modifying elements. In another embodiment, all forms and functions of modifiers of modifying elements are also depicted in a plurality of adjacent rows parallel to said ordinate, each row being ordered to correspond to the modifying elements which they modify, and each row containing only modifiers of modifying elements of a common form.

Dependent claims

A method of syntactically categorizing the constituents of an English language sentence, comprising the steps:

(a) defining all expressions of the subject of a sentence, all expressions modifying said subject expressions, and all expressions modifying said expressions modifying said subject expressions to be members of a first functional set,
(b) defining all expressions of action being performed by or upon a subject expression of a sentence, all expressions linking the subject expression to a predicate expression, all expressions modifying said action or linking expressions, and all expressions modifying said expressions modifying action or linking expressions to be members of a second functional set,
(c) defining all expressions of an indirect object of any action, all expressions modifying said indirect object expressions, and all expressions modifying said expressions modifying said indirect object expressions to be members of a third functional set,
(d) defining all expressions of a direct object of any action, all .expressions modifying said direct object expressions, and all expressions modifying said expressions modifying said direct object expressions to be members of a fourth functional set,
(e) defining all expressions which are an object of a preposition, all expressions modifying said object of preposition expressions, and all expressions modifying said expressions modifying said object of a preposition expressions to be a fifth functional set,
(f) defining all predicate expressions, all expressions modifying said predicate expressions, and all expressions modifying said expressions modifying said predicate expressions to be members of a sixth functional set,
(g) defining each member of the first through sixth functional sets which is in word form to be a member of a first form set,
(h) defining each member of the first through sixth functional sets which is a phrase to be a member of a second form set,
(i) defining each member of the first through sixth functional sets which is a clause to be a member of a third form set,
(j) defining each member of the first through sixth functional sets which is a foundation element to be a member of a first class set,
(k) defining each member of the first through sixth functional sets which modifies a foundation element to be a member of a second class set, and
(1) defining each member of the first through sixth functional sets which modifies a modifier to be a member of a third class set.

(1) defining each member of the first through sixth functional sets which modifies a modifier to be a member of a third class set,
(m) creating an image of a schema comprised of a set of individually distinct indicia, a half of the indicia corresponding to all possible forms and functions of foundation elements, and the other indicia corresponding to all possible forms and functions of foundation element modifiers, and
(n) matching or attempting to match the constituents of the sentence with their corresponding indicia of the schema image.
