The Bioz vStar rating is a multi-parameter data-driven algorithmic quality score that is based on multiple weighted parameters. The core parameter is the average quality rating (Bioz Stars) of all of a vendor’s products. Other Bioz vStar rating parameters include, vendor reputation, size, and product count. Bioz vStars distinguishes itself from Bioz Stars, in that the Bioz Star rating represents the quality rating of a single product, whereas Bioz vStars is the average quality rating of all of a vendor’s products.
The Bioz vStar rating algorithm factors in data that is extracted from scientific articles, together with relevant validation parameters.
The information that we take into account is all publicly available. However, we don’t share the inner-workings of the Bioz vStars algorithm, so that we can maintain the rating’s neutrality and integrity. Moreover, we do not disclose the weight that we assign to each parameter, so that it isn’t possible for a vendor to artificially manipulate or boost their ratings through unfair advantage. Bioz Stars and Bioz vStars can never be artificially altered or boosted; in particular, they cannot be influenced, altered or increased as a result of payment of a fee, sponsorship, advertising, or other forms of payment. Transparency, objectivity, and zero bias are at the core of the Bioz ethos.
Absolutely not! Bioz assigns a vStar rating to every product that we are able to identify as not being mentioned within a life science article. If you notice any information that you know to be incorrect, please contact Bioz and we will investigate the issue.
Bioz vStars are based on a deep analysis of hundreds of millions of life-science products that are mentioned in papers, which makes it a strong indicator of product and assay quality. Nevertheless, Bioz vStars is only one piece of information that you can use to evaluate whether a particular lab product is right for you. One should remember that the Bioz vStar rating is not specific to a single product, and that it is not directly based on being mentioned in articles. The Bioz vStar rating is based on the assumption that if a vendor has other high-quality products, then it is likely that its other products will also be high-quality, and vice versa. Bioz vStars guide researchers in their product evaluation process when a product doesn’t have any article mentions, and therefore, a Bioz Star rating is not associated with it. A product may not have any article mentions due to one or more of the following reasons: (1) It is a new product, (2) It is rarely used, (3) It is the type of product that researchers do not typically mention in articles. The Bioz vStar rating is a tool that provides a snapshot assessment, and should be considered alongside other information, including Bioz’s unique experimentation insights, that have been identified and structured from within article excerpts.
