Towards Personalized Bangla Book Recommendation: A Large-Scale Heterogeneous Book Graph Dataset

arXiv:2602.12129v2 Announce Type: replace-cross Abstract: Personalized book recommendation in Bangla literature has been constrained by the lack of structured, large-scale, and publicly available datasets. This work introduces RokomariBG, a large-scale heterogeneous book graph dataset designed to support research on personalized recommendation in a low-resource language setting. The dataset comprises 127,302 books, 63,723 users, 16,601 authors, 1,515 categories, 2,757 publishers, and 209,602 reviews, connected through several relation types and organized as a comprehensive knowledge graph.

Why this matters
Why now

The proliferation of AI models demands high-quality, domain-specific datasets, particularly for low-resource languages, making this dataset's introduction timely for expanding AI accessibility.

Why it’s important

This development addresses a critical gap in data availability for personalized AI in a low-resource language, potentially fostering local AI innovation and reducing reliance on global AI stacks trained on dominant languages.

What changes

The existence of this large-scale Bengali book dataset enables the development of more accurate and culturally relevant recommendation systems and AI applications for Bangla speakers, previously hindered by a lack of structured data.

Winners
  • · Bangladeshi AI developers
  • · Bangla-speaking consumers
  • · NLP researchers in low-resource languages
Losers
  • · Global tech companies without localized data strategies
  • · Generic recommendation systems
Second-order effects
Direct

Increased research and development in personalized AI for Bangla.

Second

Emergence of more culturally nuanced AI services and applications tailored for the Bangla-speaking population.

Third

Potential for sovereign AI initiatives in Bangladesh, building on localized data infrastructure and models.
