Knowledge Representation & Processing

676 views

Published on

Knowledge is a very common and widely used word but it is hard to find a comprehensive and precise definition of knowledge---particularly in the context of humans and machines. Same is the case of "meaning" which is related to "knowledge".

Here is a proposal of definition of knowledge and a knowledge builder server HyperPlex initiated during 90s and formulated in the present form in 2008.

We claim that HyperPlex has high expressive power and precision than KIF, RDF and UNL.

  3. 3. • Knowledge Rep & Processing What is Knowledge is NOT 22 JAN 14 Knowledge is NOT  Data & information NOR  The Contents of:   http://www.slideshare.net/putchavn/concept-mapsknowledge-encoding and  Knuth’s definitions of data and information  http://www.slideshare.net/putchavn/knuthsdefinitions-of-data-and-information-04-mar13  Books, Dictionaries, Encyclopedias ?  Files, Databases? This builds on Concept Maps & Knowledge Encoding 3
  4. 4. What Knowledge is Knowledge Rep & Processing 1. How about people, DBMS, Search Engines, do they have 22 JAN 14 knowledge? 2. Yes, they have knowledge  Why do we say yes for 1 and  NO for books, files & databases  What is the difference?  See the following explanation and the proposed definition 4
  5. 5. Entities, NOT media, have Knowledge Essentially data & information Knowledge Rep & Processing Stimuli 22 JAN 14 Environment response Essentially data & information has ability To Receive, Hold, Process and or create data / Information & deliver them That is Knowledge 5
  6. 6. Knowledge: Proposed Definition Knowledge Rep & Processing  22 JAN 14  Knowledge is the ability of an entity to respond To Hold, Process To Stimuli Expressions of Knowledge are D & I But D & I are not K To deliver D & I and or create data / Information Queries of specified types within a Domain See http://www.slideshare.net/putchavn/knuths-definitions-of-data-andinformation-proposed-definition-of-knowledge-03-mar13 6
  7. 7. Knowledge Representation Knowledge Rep & Processing  22 JAN 14 Based on the definitions      of data & information and knowledge Knowledge representation is a way of encoding the content so that: Computer and its software can    Manipulate that content To generate responses That a good knowledge source would generate Encoding & processing gives that ability i.e., knowledge to computers & software 7
  8. 8. Knowledge Representation Standards  Knowledge Rep & Processing  22 JAN 14    Knowledge Interchange Format KIF Resource Description Framework RDF Universal Network Language UNL Perhaps more Their basic principles appear to be similar  Our proposed HyperPlex     Has more Expressive Power & Precision Open to checkingg See http://www.slideshare.net/putchavn/knuths-definitions-of-data-and-information-proposeddefinition-of-knowledge-03-mar13 8
  9. 9. HyperPlex for Meaningful Query-Response Knowledge Rep & Processing  22 JAN 14    Now you may take a look at our HyperPlex (link in next slide) It is a High Precision Knowledge Authoring and Query-Response System Based on Concept Maps with Nodes and Links having well defined microstructures     As a result HyperPlex is capable of encoding, decoding and processing Knowledge with high-precision It addresses and deals with What we call meaning to the extent the meaning is encoded using the microstructures 9

  11. 11. Conclusion Knowledge Rep & Processing  22 JAN 14  Could not find clear & usable definitions of Knowledge and meaning Particularly those valid in human and machine contexts    A definition of knowledge (first proposed in 2000) is explained It enables encoding knowledge for machine processing KIF, RDF, and UNL which evolved around 2000 are similar but (we believe) lack expressive power & precision of our HyperPlex 11
