Bioz Stars

When researchers choose reagents, tools, kits, instruments, equipment, and other products for their life science experiments, they look to the stars…the Bioz Stars…the world’s only trusted and objective confidence scores for life science products.
Bioz Stars - The Industry Standard!
  • 100% objective
  • Transparency article sentences are displayed
  • Actual usage data scores cannot be influenced
  • Trusted data source published peer-reviewed articles
  • The industry standard adopted by researchers & vendors
For researchers, a quick check of a product’s Bioz Stars score and its article sentences, is all that is needed for them to choose a product with confidence!
"What previously took me months to find when working on a new experiment, I found in mere minutes with Bioz."
- Professor Giles Plant
Comprehensive & Dynamic
Bioz Stars scores guide researchers towards the best products to purchase for their life science experiments, with the number of stars indicating the likelihood that a product will work well in their experiment. Within each product category, products that have been used more frequently and more recently than other products, as documented in published articles, receive higher Bioz Stars scores.
The Bioz Stars algorithm assigns scores to products on the following 100-point scale:
  • 95-100 Excellent (a top selection)
  • 90-94 Great
  • 85-89 Very good
  • 80-84 Good
  • 75-79 Mediocre
  • 01-74 Not recommended
The Bioz A.I. engine has already analyzed 27 million life science articles, and has identified 300 million different products from 50,000 vendors. Every day, thousands of new life science articles are published, from which Bioz generates new product mentions. These new product mentions are automatically added to and Bioz Badges, and result in each product’s Bioz Stars score dynamically adjusting up or down (based on the number and frequency of new product mentions).
The Bioz Stars algorithm analyzes multiple scoring parameters that are weighted, normalized and standardized. The primary factors include:
  1. Product Mentions Index (product popularity relative to corpus)
  2. Article Recency (date of the article in which the product was identified)
  3. Journal Impact Factor (as published annually by Thomson Reuters)
  4. Article Citation Strength (citation count relative to extracted entity mentions)
  5. Efficacy Factor (entity popularity within a category, relative to the corpus average)
  6. Tendency Factor (entity popularity relative to category average)
  7. Timeline Slope Factor (product usage timeline trend anomaly adjustment)
  8. Product Recency (product age relative to corpus)
  9. Search Frequency (number of times a product appeared in Bioz search results)
  10. Product Preference Depth (product details page visits)
  11. Quick-View Interest (quick-view visits)
  12. Vendor Button Clicks (vendor button click frequency)
  13. Score Normalization (relative to category)
  14. Score Standardization (relative to category)
  15. Manufacturer Factor (original manufacturer weighting adjustment)
The industry standard for selecting products
Over a million life science researchers in academia and biopharma use Bioz to make decisions on which products to purchase for their experiments.
The top life science tool vendors are displaying Bioz Stars scores on their websites, with hundreds more rapidly adopting Bioz Stars to highlight that their products have been used successfully by life science researchers in academia and biopharma.
"We've only just started working with Bioz and are already seeing a positive impact. Our sales team is sharing the badge information with prospective customers who are using the objective ranking to influence purchase decisions."
- Bill Campbell, VP Marketing at Covaris
The Bioz Stars scoring algorithm uses advanced A.I. technology that is backed by 3 Nobel Prize winners, mathematicians, A.I. & data science experts from Google, and the former CTO of Microsoft.
Bioz is the world’s most objective and trusted recommendation engine for life science products.
Bioz it!
Frequently asked questions
How do Bioz Stars help you select the best tools, reagents, lab equipment, assays, etc.?
Bioz Stars scores guide you towards the best products and tools to purchase for your life science experiments, with the number of stars indicating the likelihood that a product will work well in your experiment. Products that have been used more frequently and more recently than other products, as documented in published articles, receive higher Bioz Stars scores. By selecting products with the most stars, you will be increasing the likelihood that your experiments will be successful.
Are Bioz Stars scores objective?
Yes, Bioz Stars scores are 100% objective, and have ZERO BIAS. The stars are calculated using a sophisticated multi-parameter mathematical model, with all products and tools evaluated based on the same objective set of criteria. We don’t use any human-generated reviews, as they are inherently biased. By basing Bioz Stars scores exclusively on measured product usage data, as documented in peer-reviewed published life science articles, you are getting a direct glimpse into which products worked well for other researchers. Bioz is your trusted source for decision-making guidance when selecting the best products and tools for your experiments. A.I. experts, 3 Nobel Laureates, experienced mathematicians, and data scientists from Google, have validated the accuracy of Bioz Stars scores.
Are vendors able to influence the Bioz Stars scores of their products?
The Bioz Stars scoring algorithm cannot be influenced by outsiders, whether they be researchers or vendors, period! At Bioz, all products, tools, reagents, kits, lab instruments, and lab equipment are treated equally. We don’t play favorites, and life science tool vendors can’t pay us to improve their Bioz Stars scores. The scores are never artificially altered or boosted; in particular, the scores can neither be influenced nor altered as a result of payment of fees, sponsorship, advertising, or other forms of payment. Objectivity and elimination of bias is our goal. ZERO BIAS is at the core of Bioz.
Does Bioz publish the details of how Bioz Stars scores are calculated?
The core factors that the Bioz Stars scoring algorithm takes into account are detailed above. We don’t share the inner-workings of the algorithm so that we can maintain the neutrality and integrity of the Bioz Stars scores. Moreover, we do not disclose the weights that we assign to each factor, so that it isn’t possible to boost scores by “gaming the system” to gain an unfair advantage.
Do vendors have to pay for their products to be listed on Bioz and to receive Bioz Stars scores?
Absolutely not! Bioz generates Bioz Stars scores for every product that our advanced A.I. is able to identify within 27 million published peer-reviewed life science articles. lists 300 million products from 50,000 vendors.
