Present situation of Sanskrit
  • Sanskrit colleges are like 'zoo'!
  • No Govt. support unless we are productive !!
  • Sanskrit is being neglected
  • How far this support will continue ?
  • Great tradition of learning is being lost
  • No scope for novel research

4
Innovation is the key
  • Sanskrit Shastras are competent enough to enter
    the science world.
  • Move out of Humanities and get merged with
    science.
  • Analogy Maths, psychology, Logic.
  • We must find practical approach for these
    Sanskrit Sciences.

5
we have lost 80
  • Meemamsa - No practical approach !
  • Nyaya - No use in modern dialectics ?
  • Vyakarana No application ??
  • What to do ?

6
Relevance of Sanskrit Shastras in Modern
Technology
  • fortunately these shastras are found relevent in
    todays technology
  • Computing ideas in Panini
  • Text processing principles in Meemamsa
  • Formal languages in Nyaya
  • we lack the technology and application area

7
Know How
  • Ultimate aim finding appropriate place for
    sanskrit Shastras
  • Method solutions to contemporory problems
    adopting modern technology
  • Resource needed Adequate manpower, who act as a
    bridge between modern scientists and
    technologists one side and sanskrit scholars on
    the other side.

8
Change the scenario
  • Technology
  • Western Theories
  • INDIAN THEORIES

9
Opportunities missed
  • Industrial revolution
  • We missed this with some hasty decisions
  • IT revolution
  • Indians are serving in the level of coding not
    in designing level !
  • Knowledge Revolution
  • we should take this advantage

10
Need of the hour
  • we need
  • to understand how technology works
  • to understand the contempomporary problems
  • Then
  • we will be able to give solutions in the light of
    sashtras and show the relevence of Indian theories

11
History and Progress
  • Conference held at Bangalore in Dec 1987 on
    Knowledge Representation and Sanskritam
    generated tremendous interest
  • Nothing much has been archived, except some
    efforts and projects here and there in small
    scale that too in technical institutions
  • Time running out ! What progress has been made
    since then?

12
Who would bell the cat ?
  • It needs a long interaction between technologists
    and Traditional Sanskrit Scholars
  • Technical institutions are always ready for such
    activities
  • There is NO much interest is seen in Sanskrit
    Institutions
  • It is we Sanskritists should to bell the cat

13
Long process like extraction of ghee from milk
  • Nothing miracle happens in the initial stage
  • Its a big challenge, one OR two persons are not
    enough
  • We need hundreds of dedicated persons to achieve
    a small goal
  • A person can climb a small hill Team can climb
    the Everest

14
Platform For Innovation
  • To achieve this Rashtiya Sanskrit Vidyapeetha has
    set up a view Innovative centre for advanced
    study and research in shabdabodha and language
    technology
  • Center has faculty from shabdabodha (Nyaya
    Vyakarana Meemamsa), NLP and computer science
  • Center has full-fledged computer lab

15
Possible areas
  • Machine Translation
  • Speech Processing
  • Summary Extraction from huge texts
  • Indo Wordnet as a base for IL-wordnets
  • Developing Tools for IL Researchers
  • Knowledge Representation schemes

16
Machine Translation
  • English To Indian Languages
  • Word sense disambiguation
  • Karaka Syntax Relation
  • Word-grouping
  • Idiomatic Expression
  • Shabdasutra
  • MT among Indian Languages
  • Bi-language Electronic Dictionaries
  • Karaka Vibhakti Relation

17
Summary Extraction
  • Meemamsa Principles applied to extract the
    summary of a text
  • Upakramaadi Tatparya Lingas are used to extract
    the summary of a text in Indian Institute of
    Science, Bangalore, in our consultancy.

18
Wordnet / Concept-net based on NN ontology
  • Wordnet is an electronic lexical reference
    resource system designed on the basis of semantic
    relations of words
  • Synonymy Graha, nivaasa,.
  • Hypernymy Amra, vriksha, vanaspati
  • Antonnymy Shreemaan, akinchana
  • Mecronymy nAsika, mukha, shariira..
  • Gradation Shushka,tara,.tama

    translations on web and CD R form
  • Statistical analysis of Sanskrit Texts

20
Knowledge Engineering
  • Representation
  • For Data representation, several databse
    management systems are available.
  • For representing and retrieving useful
    information, there are various worked out
    methodologies
  • Finally Knowledge Representation needs special
    treatment where Indian Knowledge systems can be
    applied

21
Knowledge and its importance in AI
  • AI researchers are interested in building
    Intelligent systems
  • Web technologies looking forward to Semantic webs
    instead of syntactic web
  • Knowledge is more valuable than data and
    Information
  • Data simple DoB. Info Age calculated.
  • Knowledge the judgment about suitability for
    job at hand etc. This requires a lot of inputs
    from various K- sources.

22

  • Dhaturatnakara All the forms of all roots will
    be made available on CD R.

  • Morphological analyser Hosted on web
  • Sandhi spliter (Under progress)
  • Samasa tag interpretor - Ready

26
Future Projects
  • Text to speach for Sanskrit texts
  • High quality search engine for Sanskrit E-library
  • Hypertext archive for Sanskrit Literature

27
