MMT: A Multilingual and Multi-Topic Indian Social Media Dataset

open access: yesProceedings of the First Workshop on Cross-Cultural Considerations in NLP (C3NLP), 2023
Social media plays a significant role in cross-cultural communication. A vast amount of this occurs in code-mixed and multilingual form, posing a significant challenge to Natural Language Processing (NLP) tools for processing such information, like language identification, topic modeling, and named-entity recognition.
