A Bengali-Hindi-Telugu parallel corpus for enhanced literary machine translation

. The development process of BHT25 followed structured data cleaning, preprocessing, sentence alignment, and human validation procedures. Each sentence triplet is assigned a unique identifier to ensure traceability and a systematic analysis. The dataset is released under the CC-BY-4.0 license on Hugging Face, along with preprocessing scripts and documentation, to support research on Indic machine translation and multilingual literary processing. An extended version, annotated with four emotion labels (joy, sadness, anger, fear) and pairwise semantic similarity scores, is also included to support future research on emotion-aware translation and semantic consistency.
