2. Preface Draft idea only Something may be informal – Formula sign may be informal, such as, dark delta – No any axioms – Not enough Mathematical sense 2

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 3

4. Underlying Knowledge (UK) Concept UK 4

5. 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) 5

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 6

7. Underlying Community Knowledge (UCK) DC Concept UCK 7

8. Underlying Community Knowledge (UCK) DC 1 UCK 1 Name Family name First name = 8

9. Underlying Community Knowledge (UCK) DC 2 UCK 2 Name Family name First name = 9

10. Delta Represent differences of UCKs Describe associate between UCKs I may use symbol Δ 10

11. Delta UCK 1 Name Family name First name = UCK 2 Name Family name First name = 11

12. Delta I may define UCK1 / UCK2 Describe differences of UCK1 from UCK2 UCK2 / UCK1 Describe differences of UCK2 from UCK1 12

13. Delta I may define UCK1 / UCK2 UCK1UCK2 UCK2 / UCK1 UCK1UCK2 13

14. Delta I may define UCK1 / UCK2 UCK2 / UCK1 UCK1 / UCK2 but So 14

15. Delta Represent differences of UCKs Describe associate between UCKs I may use symbol Δ Δ with an UCK can construct another UCK 15

16. Delta I may define UCK1 UCK2 UCK1UCK2 UCK1 /UCK2 UCK1 UCK2 UCK1 UCK2 UCK2 / UCK1 UCK1 /UCK2 How UCK2 differ from UCK1 How UCK1 differ from UCK2 16

17. 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” 17

18. Idea It should have a reference knowledge that all DCs are agree. I may define the reference knowledge as absolute knowledge called Underlying Global Knowledge (UGK) It means that UCKs are relative to UGK Differentiate between UCKs is referred by UGK 18

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 19

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 20

21. Unreliable Evolution Concept UK v.1 Concept UK v.2 Concept Time 21

22. Unreliable Evolution UK v.1 UK v.2 I may use this sign to represent delta unreliable evolution Time 22

23. Reliable Evolution Concept UK v.1 Concept UK v.2 Concept Time 23

24. Reliable Evolution UK v.1 UK v.2 I may use this sign to represent delta Reliable Evolution Time 24

25. 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 25

26. Unreliable Derivation Concept UK 1 UK 2 26

27. Unreliable Derivation UK 1 UK 2 I may use this sign to represent delta of unreliable derivation 27

28. Reliable Derivation Concept UK 1 UK 2 28

29. Reliable Derivation UK 1 UK 2 I may use this sign to represent delta of reliable derivation 29

30. Example 1 UGK past Future UCK A UCK B Case of people are under difference UCK 30

31. Example 1 UGK past Future UCK A UCK B Creator under UCK-A created a document D Reader under UCK-B may not understand the document D Create D Read D 31

32. Example 1 UGK past Future UCK A UCK B 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 / UCK A D UCK B / UGK Create D Read D’ 32

33. Example 2 UGK V1 past Future UCK A UCK C 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 UGK v1 / UCK A D UGK V2 Create D Read D’ UGK V2 / UGK V1 UCK C / UGK V2 33

34. Example 3 UGK V1 past Future UCK A1 UCK A2 In this case, the UCK A2 is an evolution of UCK A1 UGK V2 Create D Read D’ 34

35. Example 3 It has possible 2 choices 1 D’ UGK v1 / UCK A1 D UGK V2 / UGK V1 UCK A2 / UGK V2 2 D’ UCK A2 / UCK A1 D And 35

36. Example 3 I prefer to choose the simple one D’ UCK A2 / UCK A1 D 36

37. D and D’ Relation between D and D’ in the theory is D’ D D’ has preservability relation with D 37
