Overview

Turn hundreds of millions of public product reviews into structured feedback on quality, packaging, delivery and value, in English, Hindi and Hinglish.

What's included

  • Review text, star rating, review date, verified-purchase flag and helpful votes
  • Product ID linking each review to the Bazaarlens catalog and brand
  • Language label (English, Hindi, Hinglish, Tamil, Telugu, Bengali, Marathi) and a machine translation to English
  • Aspect-level sentiment for 18 aspects such as quality, fit, fragrance, packaging, delivery and after-sales service
  • Spam and incentivized-review likelihood score

How buyers use it

  • Brand teams track complaints by product, pack size and launch batch
  • Product developers mine unmet needs before reformulating or redesigning
  • Insights teams benchmark sentiment against competitor brands
  • Data scientists train review classifiers and sentiment models under the separate AI training licence

Coverage and methodology

Reviews are collected from public product pages only. Reviewer names, profile links, photos and any other identifiers are dropped at collection and never stored, and phone numbers or email addresses typed into review text are masked before delivery. Aspect labels come from a multilingual classifier fine-tuned on 120,000 human-annotated reviews; quarterly spot checks show 89% agreement with annotators on aspect sentiment. History starts in 2019 for the top 40 categories and in 2022 for the rest.

    Review sentiment fed straight into our roadmap

    Aspect-level sentiment on noise, build quality and after-sales service showed exactly where our mixer grinders lost to competitors. Reviewer identities are stripped, which kept our legal team happy.

    Seller sales estimates are directional

    The assortment data is very good. Estimated sales for sellers are useful for ranking competitors but were off by a fair margin for two sellers whose real numbers we know. Treat them as relative, not absolute.
