Preface

• Draft idea only• Something may be informal– Formula sign may be informal, such as, dark delta– No any axioms– Not enough Mathematical sense

Page 3: Propose a theory

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)

Page 6: Propose a theory

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

• Represent differences of UCKs• Describe associate between UCKs• I may use symbol Δ

• I may define

UCK1 / UCK2

Describe differences of UCK1 from UCK2

UCK2 / UCK1

Describe differences of UCK2 from UCK1

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”

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

Page 19: Propose a theory

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

Page 20: Propose a theory

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
