Propose a theory

1. Propose a theory RathachaiChawuthai

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

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

4. Underlying Knowledge (UK) UK Concept Concept Concept Concept Concept

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)

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

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

8. Underlying Community Knowledge (UCK) UCK1 First name = Name Family name DC1

9. Underlying Community Knowledge (UCK) UCK2 First name = Name Family name DC2

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

11. Delta UCK1 First name = Name Family name UCK2 First name = Name Family name

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

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

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

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

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

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”

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 ReliableEvolution

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

21. Unreliable Evolution Concept Concept Concept Concept Concept Concept Concept Time UKv.1 UKv.2

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

23. Reliable Evolution Concept Concept Concept Concept Concept Concept Concept Time UKv.1 UKv.2

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

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

26. Unreliable Derivation Concept UK1 Concept Concept Concept UK2 Concept Concept

27. Unreliable Derivation UK1 I may use this sign to represent delta of unreliable derivation UK2

28. Reliable Derivation Concept UK1 Concept Concept Concept UK2 Concept Concept

29. Reliable Derivation UK1 I may use this sign to represent delta of reliable derivation UK2

30. Example 1 Future past UGK UCKB UCKA Case of people are under difference UCK

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

32. Example 1 Future past UGK Create D Read D’ UCKB UCKA 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 D’ D UCKB/ UGK UGK / UCKA

33. Example 2 Future past UGKV2 UGKV1 Create D Read D’ UCKC UCKA 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 D’ D UGKv1 / UCKA UGKV2 / UGKV1 UCKC / UGKV2

34. Example 3 Future past UGKV2 UGKV1 Create D Read D’ UCKA2 UCKA1 In this case, the UCKA2 is an evolution of UCKA1

35. Example 3 It has possible 2 choices 1 D’ D UGKv1 / UCKA1 UGKV2 / UGKV1 UCKA2 / UGKV2 And 2 D’ D UCKA2 / UCKA1

36. Example 3 I prefer to choose the simple one D’ D UCKA2 / UCKA1

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