Wiring Up
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.

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.

Sample Verb Structures
ToPay
Tenant is paid to wash
the windows
ToUse
He used the lease to obligate Lessee
to pay John the rent

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

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.

Logical Control

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.
