Recent Advancements and Challenges in Bangla Textual Document Classification: A Review

Bengali is the world's sixth-most frequently used dialect. Natural language processing (NLP), which enables data scientists to extract useful information from the constantly growing quantity of text data available on the net, includes text categorization as a key component. It is the act of organizing already-created groups or classes of text documents. But compared to other languages, like English, Bengali does not have as many capabilities for classifying texts. This study offers an extensive analysis of the current categorization of Bengali documents. Also gives a comprehensive summary of recent advances in ML and DL, covering datasets, methods, performance, accuracy rate, classification category, strengths, and limits. The purpose of this discussion is to identify current challenges that must be addressed and recommend some guidelines for future studies that might be explored.
