Sentiment Analysis for Kannada–English Code-Mixed Social Media Text

Abstract

The exponential rise of social media has led to the generation of a large amount of informal text. Especially, code-mixed languages have gained substantial popularity among social media users. In India, the code-mixed language Kannada-English is widely used in social media platforms. This informal and non-standard language form brings forward significant challenges to natural language processing (NLP) tasks like sentiment analysis. This paper presents a detailed analysis of sentiment analysis in kannada-english code-mixed social media text. A manually annotated dataset is created and classified into positive, negative, and neutral sentiment labels. Various kinds of machine learning, deep learning, and transformer-based models are evaluated. The results suggest that the transformer-based models trained on Indian language corpora outperform others. Furthermore, this paper provides a comprehensive set of observations regarding sentiment analysis of Indian language code-mixed social media text.
