Brief Speaker Bio :
Prof. Pushpak Bhattacharyya, Fellow of National Academy of Engineering and A.P.J. Abdul Kalam National Fellow, is former Director of IIT Patna (2015-20) and Professor of Computer Science and Engineering Department IIT Bombay where he also held the Vijay and Sita Vashi Chair Professorship. Prof. Bhattacharyya is currently the Professor-Incharge too of Data and Information Sciences Lab under the Institute of Eminence activity of IIT Bombay. He was raised in the picturesque town of shillong in Meghalaya where he was the state topper in both class 10th (1977) and class 12th (1979) examinations. He was educated in IIT Kharagpur (B.Tech, 1984; also chosen as its Distinguished Alumnus in 2018), IIT Kanpur (M.Tech, 1986) and IIT Bombay (PhD, 1994). He has been visiting scholar and faculty in MIT, Stanford, UT Houston and University Joseph Fouriere (France). Prof. Bhattacharyya’s research areas are Natural Language Processing, Machine Learning and AI (NLP-ML-AI). His lab called "Center for Indian Language Technology" (CFILT) at IIT Bombay is known internationally for its contribution to NLP and ML. In IIT Patna too, the lab called "Center of Excellence in Natural Language Processing" is gaining visibility in the country and abroad.
Prof. Pushpak Bhattacharyya has worked in all areas of Natural Language Processing- machine translation, sentiment and opinion mining, cross lingual search and multilingual information extraction. He combines linguistics, cognitive science and machine learning in a unique way. He has published more than 300 research papers. Multilingual Lexical Knowledge Bases and Projection and Computational Sarcasm are his reasearch trail-blazers. Author of the text book ‘Machine Translation’ Prof. Bhattacharyya has shed light on all paradigms of machine translation with abundant number of examples from Indian Languages. Two recent monographs by him called 'Investigations in Computational Sarcasm' (with Dr. Aditya Joshi) and 'Cognitively Inspired Natural Language Processing- An Investigation Based on Eye Tracking' (with Dr. Abhijit Mishra) describe cutting edge research in NLP and ML.
Prof. Bhattacharyya has guided more than 250 students (PhD, masters and Bachelors); he is loved by his students for his friend-phillosopher-guide approach to mentorship. Students mentored by Prof. Bhattacharyya are faculty members in IITs, NITs, IIITs and Universities, and also are industry leaders and members of top research labs.
Ministries, Government organizations and leading industries have benefitted from Prof. Bhattacharyya's expertise. The list includes MEITY, MHRD, MoC, MEA, NITI Aayog, CDAC, Accenture, Elsevier, Microsoft, IBM, Honeywell, Samsung, HCL, LG, Emirates Airlines, and startups like Bluepool, Scribetech, FreshGravity etc. He has led government and industry projects of international and national importance. Sponsored projects and consultancy projects executed by Prof. Bhattacharyya run into multiple crores.
Over the years, Prof. Bhattacharyya has been rendering professional service in various capacities. He has been President (2016-17) of Association of Computational Linguistics (ACL) the highest International body defining standards of and propagating Computational Linguistics. He is currently serving as Chairman of Committee for Standardization in Artificial Intelligence, set up by Bureau of Indian Standards under Ministry of Consumer Affairs in 2018, whose members include IITs and IISc, CSI, MEITY, NITI Ayog, CAIR DRDO and leading industries like TCS, Google India, IBM Software, Samsung, Intel Research, and Microsoft Research. He has been a founding member (2017) of Asian Association for Computational linguistics (AACL) and South Asian Association for Language Processing (SAALP) (2005). He organized one of the major international conferences on computational linguistics- COLING 2012 in Mumbai.
Prof. Bhattacharyya has been a propagator of NLP, its foundations, state of art and Indian Language Technology. Starting with educational institutes in and around Mumbai, he has lectured in IITs, IISc, NITS, IIITs, MIT, Stanford, University of Chicago, Oxford University, Grenoble University, University of Texas at Houston etc. Similarly, he has delivered invited talks in industries and research labs like IBM, Microsoft, Yahoo, Apple, NVIDIA, Accenture, Honeywell, Adobe, CDAC, CDOT and others.
Prof. Bhattacharyya's research has gained national and international visibility. His work on Computational Sarcasm with his students featured in The TIMES London Edition, 19th Sept, 2017 (Link) and also in Hindustan Times, 22nd August, 2018 (Link). The deep learning based sarcasm research also featured in MIT Technology Review and ACM Tehnology News (Link). A recent web analysis places Prof. Bhattacharyya in the list of most prolific researchers on NLP and ML for the period 2012-17 (Link). Another such very recent web analysis places Prof. Bhattacharyya amongst top 10 machine learning researchers of the country (Link).
Prof. Bhattacharyya is Fellow of Indian National Academy of Engineering (FNAE) (elected 2015). For sustained contribution to technology he received the Manthan Award of Ministry of IT (2009), P.K. Patwardhan Award of IIT Bombay (2008) and VNMM Award of IIT Roorkey (2014). He is Distinguished Alumnus Awardee (2018) of IIT Kharagpur. In 2020, he was conferred the prestigiuos Abdul Kalam Technology Innovation National Fellowship.
Title of Talk
AI for Society: the Role of Natural Language Processing
In this talk we will present our two decade long work on many areas of natural language processing like machine translation, sentiment and emotion analysis, information extraction and so on. Machine Learning and data have played a very important role in this research. The role of NLP and ML in societal benefit is supreme. We will discuss a few cutting edge and impactful applications in this talk.
