ORIONActive Structure

The process that converts text to a usable structure

ORIONActive Structure

Only A Prolog

The process of parsing is only a prolog to the main event - the connecting of pieces of

structure to represent the meaning of the text. It is nowhere near one for one, more like a

jigsaw, with some pieces creating new pieces as they fit together - a simple preposition like “for” able to create cycling logical machinery.

Noun Phrases

As soon as a noun phrase is recognised, it is pulled apart and structure to represent it is built

“The delayed response” will result in the creation of a delay relation, and the attachment of it to the response object. The response object (itself a relation) will then be propagated as the object representing the noun phrase.

ORIONActive Structure

Verb Phrases

Verb phrases are turned into relations, with any verb auxiliaries that are present controlling how existence and logic operate on the relation. Any special properties, such as passive voice, are applied to the relation so they can later be used in matching by prepositionals.

Sample Verb Structures

ToPayTenant is paid to washthe windows

ToU se

He used the lease to obligate Lesseeto pay John the rent

ORIONActive Structure

Prepositional Phrases

Prepositional chains are identified and the network of relations set up for analysis. Prepositions can jump over each other or, like “by”, make a beeline for the leftmost object

ORIONActive Structure

Logical Connection

Each sentence results in a logical or existential connection, which is an attribute of the sentence object, and its state is controlled by the discourse.

That is, there is a logical spine running through the discourse, controlling the elements.

Invariant Structure

The resulting structure is reasonably close to invariant - except for synonyms, no matter how you say it, for the same meaning the same structure gets built.Relations can be explicit in verbs, or hidden in nouns, adjectives, adverbs - the same relation will be built, although with less control over logic and existence than there is with verb auxiliaries.This invariance makes searching and simulation much easier.
