Propose a theory

Preface
• Draft idea only• Something may be informal– Formula sign may be informal, such as, dark delta– No any axioms– Not enough Mathematical sense
3
Underlying Knowledge (UK)
• UK – contains Concepts which are encoded from real-world
concept.• Concept – Is represented by Language– Enumerates until Atomic Concept
• E.g. “Name” must enumerate to “First name”, “Middle name”, and “Family name”
• Language– Is common and formal – Must be able to capture and express knowledge

Designated Community (DC)
• DC is a group of people who– Have common knowledge (concept)– Have common background– Have common contextual knowledge– Have same language
• Knowledge of DC called Underlying Community Knowledge (UCK)
6
Underlying Community Knowledge (UCK)
• UCK extends behaviors from UK by focusing on knowledge under community
• UCK looks like: knowledge, background, context, commonsense, semantic, and etc. that are understandable by all people in DC
• It means that People in the same DC know the same UCK and understand every Concept inside UCK

Issue of UCK
• Each UCK may have different Concepts which are same meaning; such as:– UCK1 contains a concept “Family Name”– UCK2 contains a concept “Last Name”
18
Idea
• It should have a reference knowledge that all DCs are agree.
• I may define the reference knowledge as absolute knowledge calledUnderlying Global Knowledge (UGK)
• It means that UCKs are relative to UGK• Differentiate between UCKs is referred by UGK
19
Underlying Global Knowledge (UGK)
• UGK extends behaviors from UK by focusing on common knowledge being known among DCs
• UGK must– Be defined from reliable organization– Trend to change lightly– Be able to change to new version under policy of
Reliable Evolution
20
Evolution Policy
• Evolution– Preserve modification of a version of UK to be new version of that
UK• Reliable Evolution
– Every concept in a version of UK must have association to some concepts of new version of UK
– New version of UK is able to trace back to old version of UK with lossless
– Old version of UK is able to be new version of UK with lossless as well
• Unreliable Evolution– Opposite from Reliable Evolution

UCK with UGK
• UCK must derive from UGK– Every concept in UCK must have association to
some concept in UGK– I may call this relationship is Reliable Derivation

Reader under UCK-B may not understand the document D

D’
The system should generate new digital object that the reader understand called D’. The D’ is modified from D by delta of difference knowledge between UCK

The system should generate new digital object that the reader understand called D’. The D’ is modified from D by delta of difference knowledge between UCK and evaluation of UGK

Example 3I prefer to choose the simple one
