Research
My research focuses on Natural Language Processing - in particular, I am working on developing NLP tools for linguistically rich Indian languages using deep learning algorithms. These tools can be effectively utilized in Neural Machine Translation, Indian language spoken dialogue systems, Robotics, social media text analytics etc. Along with the machine learning/deep learning tools, I also prepared datasets for different NLP tasks such as Machine Translation, Morphological analysis, Sandhi splitting, Parts-of-Speech tagging and Named Entity Recognition in Indian languages.
My research aims to take the common man to the world of flooded knowledge and let them learn through their spoken language or mother tongue.
Some topics of interest are:
Neural Machine Translation
Models of linguistically rich languages such as Sanskrit, Malayalam, Tamil, Hindi, Telugu and also for Arabic
Morphological and Sandhi splitter
Named Entity Recognition (NER) tagger
Parts of Speech (POS) tagger
Word Sense Disambiguation (WSD)
Social media text analytics
Factuality identification
Sentiment analysis
Hate speech identification
Emotion detection
Fake News Detection
Biomedical text mining
Kernel methods and explicit random feature mapping algorithms
Anomaly Detection and Intrusion Detection
