We acknowledge the help of ASR Melkote who had given their resources of Morphological Analyser in 2002. This formed a starting point for us.
-
Mr. Jain worked on the Sanskrit morphological analyser from 2002-2003 towards his M.Tech. thesis at IIIT-H.
-
Ms. Sheeba worked as a part of work on her Ph.D. thesis contributed towards the development of morphological analyser from 2004-2006. Her major contribution was for subantas and kridantas.
-
Dr. Anil Kumar contributed for the development of tinganta analyser between 2006-2007, especially with the Dhaturatnakar entries.
-
Later from 2004-2006, various students at the Rashtriya Sanskrit Vidyapeetham Tirupati contributed to the development of Sandhi package. Contribution of Ms. Sivaja Nair, Pankaj Vyasa and Ms. Sushama Vempati deserve special mention.
-
University of Hyderabad later supported further development under the University of Potential Excellence scheme from 2006-2007.
-
During 2006-2008 Pawan Goyal, IIT Kanpur worked with Amba Kulkarni towards the development of Ashtadhyayi simulator.
-
Though Amba Kulkarni worked on various modules at her own pace, the project got a boost when the Technology Development for Indian Languages(TDIL) division of Ministry of Information and Communication Technology supported the activity in the form of a Consortium of 7 Institutes (2009-13).
-
The Principal Investigators at the 7 institutes are:
- Amba Kulkarni, Department of Sanskrit Studies, University of Hyderabad (Consortium Leader)
- Dipti Mishra Sharma, IIIT-H, Hyderabad
- Girish Nath Jha, Special Center for Sanskrit, JNU, Delhi
- Veeranarayan Pandurangi, JRRSU, Jaipur
- Tirumala Kulkarni, PPVP, Bangalore
- S. S. Murty, RSVP, Tirupati
- Shrinivas Varkhedi, Director, Sanskrit Academy, Hyderabad
-
Under this project on 'Development of Sanskrit Computational tools and Sanskrit-Hindi Machine Translation system', following tools have been developed:
- Morph analyser
- Morph generator
- Sandhi
- Sandhi Splitter
- Sanskrit-Hindi Machine Translation system (Sampark and Anusaaraka models)
- Compound Processor
-
All these modules were developed at the Department of Sanskrit Studies, University of Hyderabad.
-
Various consortium members have contributed by developing annotated tests for building these modules. In addition JNU developed a POS tagger and IIIT-H deveoped a POS tagger and a parser, which are not part of this distribution.
-
During 2015-17 Amba Kulkarni was awarded a fellowship at Indian Institute of Advanced Study, Shimla. During this period she improved the parsing algorithms taking into account the yogyataa as a constraint.
-
Following persons had major contribution in the development of the tools:
- Dr. Sheeba
- Dr. Devanand Shukl
- Dr. Anil Kumar
- Ms. Bhavani
- Ms. Gauri
- Ms. Kiranmayi
- Mr. Karunakar
- Dr. Shivaja
- Dr. Shailaja
- Dr. Pavankumar Satuluri
- Dr. Monali Das
- Dr. Arjun K
- Dr. Preeti Shukla
-
In addition, Converters and Transliteration modules for converting/transliterating from one scheme to the other are developed. Following schemes have been addressed.
- Unicode Devanagari (UTF-8)
- WX
- Velthuis
- Itrans
- SLP
- Kyoto Harvard
-
Dr. Sivaja Nair worked on her Ph.D. thesis on the Amarakosha from 2007-2011. The package she developed in the process is also available for distribution.
-
Dr. Anil Kumar developed the Compound processor as a part of his PhD thesis from 2008-2011.
-
Dr. Shailaja developed the concordance of three Paninian Dhatuvrttis as a part of her PhD thesis from 2009-13.
-
Dr. Pavankumar Satuluri developed the compound generator as a part of his PhD thesis (2011-15).
-
Dr. Arjuna developed the Nyaayacitradiipikaa, an analyser for Navya Nyaya Expressions as a part of his PhD thesis (2013-17).
-
Dr. Monali Das provided the Kaaraka analysis of Sankshepa Ramayanam.
-
Dr. Preeti Patel (Shukl) developed the e-reader for SrimadBhagvadGeeta.
-
Dr. Anupama Ryali developed the e-reader for Shishupalavadham as a part of her Post Doctoral Fellowship.
-
Since 2007 Amba Kulkarni is also collaborating with Gérard Huet, INRIA. As a result of this collaboration, an inter-communication between the Sanskrit Heritage tools and the Anusaaraka tools has been possible.
-
Finally I would like to acknowledge Prof. K V Ramkrishnamacharyulu for his guidance throughout the development of these tools.
