Why Do It?
Idaho State University
• Extant typologies are implicit and subjective• Some have statistical
bases and are replicable but cumbersome
• Experts not available in day to day contexts
• AI Neural Networks accurately represents expertise with statistical rigor and highlight necessity for rethinking

Current Activity
Feeding SIGGI
• Feeding SIGGI authentic data
• Training SIGGI to make intelligent decisions
• Seeking more recent data to go beyond typology
• Evaluating quality of SIGGI’s thinking and learning

Research Databases Are Insular
Using this this technique– Each researcher has his
own island of information
– Building a unified database builds bridges
– Each island retains identity
May have own bridge

The Future
Attach a database to the interface to capture the outputs.
Modify the interface to allow for multiple artifact types and classification systems.
Design a web interface to allow secure sharing via internet access.– Three levels of availability research, private
and public.

Identification And Authentication
Controls access to the system using a two step process
Identification– Telling the system who you are
Authentication– Proving to the system that you are who you say you are
Three classic ways of establishing proof– Something you know– Something you have– Something you are
AACS
Discretionary Access Control
Capability lists– General schema
• Every object has a unique owner
• Owner possesses major access rights
• Owner may declare who has access
• Owner may revoke access
• One capability list per user
• Names all objects user is allowed access to
• Lists maintained by OS
• Users cannot access lists directly
AACS
Mandatory Access Control
In addition the system will use mandatory access control
Implements both integrity and confidentiality– Makes sure that the data can be
• Modified only by authorized individuals
• Accessed only by authorized individuals
Compartments
AACS
Examples
Levels = Research, Private, Public Compartments = University, Company,
Government, NA, EDU … Users
– Alice is logged in at a session level of “Private-Company, NA"
– Tim is logged in at a session level of “Public-University, NA, EDU"
– Anne is logged in at a session level of “Research-EDU, NA"
