Alex II
The Model
History
Alex I was developped between November 2009 and February 2010. It was based on various thoughts and questions slowly raising bewteen ~ 1990 and 2009.
Alex I was developped without any evaluation of other similar studies or research in the scientific world.
It showed some promising perspectives, but also some significant limits:
- the fusion beween words and concepts, which results in weaknesses, incoherences, conflicts, and unreachable areas
- the lack of a correct implication of numeric cognition and processing
- a too rigid description of the conscience
In Februray 2010, the Alex II project started on various fronts:
- first contacts with Iridia (H. Bersini) and Cental (C. Fairon)
- various writings in French, thoughts and explorations rather than solutions and choices
- a model overview in English (anchored here), a full description of the selected solution
- the development of java classes forming a new Alex server side.
Alex II and Alex I, as java programs, share numerous developped components:
- tools
- Janimava graphic front-end
- data structures and persistence
- client server architecture
- teaching sources
- part of node & link
New in Alex II are (limited to the major points):
- focus objects
- tripolar links
- concept and word layering
Overview
The following paragraphs and the linked pages describe the Alex II model.
Globally Alex II is organized in 2 levels:
- the jelly level, autonomous, passive, the raw material
- the conscience level, transient, dynamic, active, interacting, built on top of the jelly
Slowly dynamic part : the base jelly
The jelly includes nodes and links.
Basically, a node is a content holder. But in most case, this content is impossible to name and very difficult to describe!
Basically, a link is a connection between 2 or 3 nodes.
Fives levels of nodes: concepts / words / variants / signals
Highly dynamic part : conscience and focus
A conscience is a tree of focuses.
The root focus is the only one to persist. Other are transitional.
A focus may be described as a thread (in java language understanding).
Focus object may be either target oriented or input-driven.
