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• Nothing much has been archived, except some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

19
Sanskrit Corpus

• Annotating the relation in Sanskrit Texts
• Tagging Samasas
• Identifying the topics of the texts
• Make available Sanskrit Texts along with Simple
  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
