The recent research in sentiment analysis and code-mixed language processing has seen significant advancements, particularly in leveraging large language models (LLMs) for tasks such as sarcasm detection and translation of code-mixed texts. Innovations in this field are addressing the complexities introduced by code-mixing, where multiple languages are blended within a single utterance, often in non-native scripts. This poses unique challenges for traditional monolingual models, prompting the development of specialized corpora and methodologies. Notably, the integration of LLMs through prompting strategies has shown promising results in classifying sarcasm and sentiment polarity in code-mixed contexts, albeit with varying performance across different languages. Additionally, efforts in translating code-mixed texts to formal languages are highlighting the limitations and challenges faced by current LLMs, suggesting a need for more robust and context-aware models. The field is also witnessing advancements in interpretability tools, such as LIME, being integrated into transformer models to enhance transparency and trustworthiness in model decisions. These developments collectively push the boundaries of sentiment analysis and language translation in complex, real-world scenarios.

Noteworthy Papers:

• A novel gold standard corpus for sarcasm and sentiment detection in code-mixed Tamil-English and Malayalam-English texts demonstrates the potential of LLMs in handling complex linguistic phenomena.
• The study on translating Singlish to formal English underscores the challenges in code-mixed language translation, providing insights into the limitations of current LLMs.
