Link classification
This page is part of the theory side of the Assothink desciption.
Links are part of the jelly, and are used to link together nodes : concepts, words and variants.
Links are classified according to
- the level of connected nodes (concepts, words or variants)
- its qualified (or not) nature
Links are used to generally represent the connectivity of nodes, but also to transfer signals between excited nodes in a conscience.
Link attributes
A link is described by:
- the two connected nodes it involves
- possibly third connecting node
- 2 permeability figures, one for each side (each connected node)
- 2 propagated signals for the currently active focus
Classified Links
Concepts unqualified links - CC links
These links are bi-polar.
They are used to describe fuzzy links between any pair of concept nodes.
They form the massive part of the associative memory.
Concepts qualified links - QC links
These links are tri-polar.
They involve 2 highly connected concepts and a third - connecting - concept.
Concept to word links - CW links
These links join a concept (language independant) to a word (language dependant).
Word to variant links - WV links
These links join a word to a variant. Both are language dependant.
Building the nodes and the jelly
There is a sequential construction of the jelly (nodes and links), completely independant from the conscience and focus.
Link as an OO class
In the OO logic of the Alex II implementation, links are defined as one single class: A CC link is a QC link whose connecting concept is undefined (null). The QC tripolar links form a subpopulation, not a subclass of the link class.
Links, signal and excitation
Within a conscience or a focus, links are used to propagate signals between excited nodes. These values are produced and consumed within a running focus.
When a focus change occurs, the excitation state (concept excitation levels and waiting signals) of the focus going to sleep has to be memorized. And the possible excitation state of the focus waken up has to be restored. This is the focus state switching process.
