Natural Language Processing (NLP) is a specialized branch of artificial intelligence that enables computers to understand, interpret, and generate human language in a way that is both meaningful and contextually relevant. By bridging the gap between human communication and machine processing, NLP powers a wide range of applications, from voice assistants to automated translation and intelligent search engines.
At the Academy of Technology (AOT), research in NLP combines linguistic theory, statistical modeling, and machine learning to address challenges in text and speech processing. Faculty and students work on areas such as sentiment analysis, text classification, machine translation, named entity recognition, and question-answering systems. Cutting-edge deep learning models, including transformers like BERT and GPT, are explored for tasks involving contextual language understanding and generation. Applications of AOT’s NLP research span multiple sectors. In business, NLP-driven analytics help organizations understand customer sentiment and improve service quality. In healthcare, NLP is used to process clinical notes, extract critical patient information, and support medical decision-making. Educational applications include automated essay grading and intelligent tutoring systems. Additionally, NLP contributes to information retrieval, enabling users to efficiently access relevant content from vast databases.
A key research priority at AOT is the development of multilingual and low-resource language models, particularly for Indian languages, to ensure that technological advancements are inclusive and culturally relevant. Efforts also focus on improving model interpretability, robustness against adversarial attacks, and reducing biases in language models. Research is supported by high-performance computing facilities, NLP toolkits, and collaborative projects with technology companies and research institutions. Students gain hands-on experience in building and deploying NLP solutions, equipping them with skills highly sought after in the AI industry. Looking forward, AOT aims to explore conversational AI, multimodal NLP, and cross-lingual transfer learning, driving innovation toward more natural, accessible, and human-like language technologies.
Problem Description: We propose a novel Hidden Markov Model (HMM)-based method for limited vocabulary recognition of unconstrained mixed-cursive handwriting. Unlike traditional sub-stroke recognition, entire word samples are treated as basic units. Both circular and linear features are extracted: circular features are modelled using von Mises distributions and linear ones using Gaussian distributions. To handle handwriting variability and delayed strokes, fully connected non-homogeneous HMMs with parameter smoothing are used. Recognition combines natural and reverse order HMM results. Additionally, segmentation via discrete curve evolution and feature modelling using mixture distributions improve performance. Tests on Bangla and Latin handwritten word datasets show promising results.
Problem Description: In today’s world, both natural and man-made disasters pose serious threats to societal stability. While predicting such events is critical, understanding public behavior during crises is equally vital. Social media, as a real-time platform for public expression, captures shifts in sentiment and engagement during emergencies. However, there is a notable gap in tools that effectively quantify and forecast the behavioral impact of social media during such events. Moreover, no existing model integrates both sentiment analysis and user engagement to estimate the likelihood of environmental or societal instability, highlighting a critical need for a more comprehensive predictive framework.
Problem Description: Alzheimer’s disease (AD), a severe neurodegenerative disorder, affects millions globally and is surrounded by social stigma that hinders early diagnosis and treatment. Patients often face discrimination and internalized fear, causing them to avoid medical help. The stigma is intensified by misinformation and negative sentiments, especially on social media. Simultaneously, healthcare data systems lack adequate privacy safeguards, leading to concerns about data misuse. This research explores the integration of Natural Language Processing (NLP) for sentiment analysis and Blockchain technology for secure data handling, aiming to reduce societal stigma and improve diagnosis, privacy, and quality of life for AD patients.
Problem Description: With the explosive growth of user engagement on OTT (Over-The-Top) platforms, understanding audience sentiment through user reviews has become crucial for improving content delivery and user experience. This research investigates which machine learning algorithms perform best for sentiment analysis of reviews from major OTT apps like Netflix, Amazon Prime Video, Disney+ Hotstar, and Sony Liv. By collecting data using the Google Play Scraper API and applying models like Naive Bayes, SVM, Logistic Regression, and Decision Trees, the study aims to identify the most effective algorithm for accurate sentiment classification across diverse user feedback in the OTT domain.
