Marathi Language Processing Challenges and Advancements

Introduction

Marathi is one of the major languages spoken in India, particularly in the state of Maharashtra, where roughly half of the population uses it as their primary means of communication. As a result of global digital culture and technological advancements, researchers are increasingly interested in exploring ways to apply advanced language processing techniques to understand and analyze Marathi content. This includes sentiment analysis, which involves determining the emotional tone or attitude expressed within texts, and question answering, which aims to accurately interpret questions posed in a given language. Both areas have seen significant progress in recent years, despite challenges related to data scarcity and the complexity of Marathi as a language.

Emotion-Aware Multimodal Marathi Sentiment Analysis

One notable development is an effort called MahaEmoSen, which proposes an emotion-aware multimodal Marathi sentiment analysis system. This system goes beyond traditional sentence-level analysis to consider emotions embedded in tweets and combines textual and visual modalities from social media posts to perform sentiment classification. By leveraging machine learning techniques, including word-level attention mechanisms and data augmentation strategies, the study demonstrates improved performance compared to earlier sentiment analysis methods when dealing with resource-constrained situations.

Question Answering for Hindi and Marathi

To address the shortage of suitable question answering datasets for these under-resourced languages, there has been an initiative to translate the SQuAD 2.0 dataset into Hindi and Marathi. This translated dataset serves as a foundation for developing effective question answering systems in these languages, although these efforts still need to overcome issues surrounding data dearth and the peculiarities inherent to regional languages.

Challenges and Future Directions

Despite some promising developments, the field of Marathi language processing faces numerous hurdles. For instance, the detection of sentiment-related topics is crucial yet largely unexplored. Additionally, the construction of high-quality microblog-specific sentiment lexicons would greatly contribute to sentiment analysis systems designed specifically for Marathi. Moreover, the vast majority of computational linguistics tools and techniques have historically prioritized western languages over those of the Indian subcontinent, leaving room for improvement in the realm of Marathi language analysis.
