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

Case of people are under difference UCK

Example 1

past Future

UCKA UCKB

Creator under UCK-A created a document

D

Reader under UCK-B may not understand the document D

Create DRead D

32

Example 1

UGK

past Future

UCKA UCKB

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

UGK / UCKAD UCKB / UGK

Create DRead D’

Example 2

past Future

UCKA UCKC

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 and evaluation of UGK

In this case, the UCKA2 is an evolution of UCKA1

Example 3

It has possible 2 choices

1

D’ UGKv1 / UCKA1D UGKV2 / UGKV1 UCKA2 / UGKV2

2

D’ UCKA2 / UCKA1D

And

36

Example 3

I prefer to choose the simple one

D’ UCKA2 / UCKA1D

37

D and D’

Relation between D and D’ in the theory is

D’ DD’ has preservability relation with D
