Wiring Up ORION Active Structure The process that converts text to a usable structure

ORION Active 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.

ORION Active Structure 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.

ORION Active 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.

ORION Active 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

ORION Active 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.

ORION Active Structure 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.
