What is Polygraf AI?

Polygraf AI is an AI protocol that identifies if digital content is reliable, trustworthy, and/or AI-generated. Applied to online reviews, our free Chrome browser extension, Polygraf Trust Engine, uses our AI protocol to holistically analyze review content, product features, seller & buyer behavior, and provide you with an objective AI-generated star rating and trust score so that you can shop with confidence. Sellers can rely on the fact that reviews we analyze, good or bad, are genuine feedback from the customer experience and not from malicious actors looking to damage the brand. Satisfied customers also mean minimal returns.

What criteria are used by Polygraf Trust Engine when analyzing reviews & products?

Polygraf Trust Engine uses real-time behavioral AI in conjunction with sentiment analysis to analyze reviews. Our algorithm is holistic and also uses other parameters when determining content reliability & trustworthiness. Our analyses are in real-time and dynamic – as users write reviews for products, our AI updates Trust scores, snapshots & ratings at the reviews, products, and seller levels. It’s also always learning, so the more reviews we analyze – the more accurate and nuanced feedback you get.

What e-commerce websites is Polygraf Trust Engine currently available on?

Polygraf Trust Engine is presently available for products and reviews on Amazon, and but will soon be available for a variety of e-commerce platforms in the US and globally.

What are Polygraf Trust scores and how are they calculated?

Polygraf Trust Engine generates trust scores at 2 levels: (a) At the individual review level: We calculate our trust score for each review by using our advanced AI engine. Our AI engine considers a range of factors including the history and reputation of the writer, the language used in the review, the writer's tonality, and the consistency of the review with other reviews for the same and competing products. Our AI uses these factors to generate a holistic score that indicates the level of trust you can place in that review. (b) At the product level: This is an overall trust score that is based on an aggregate of the reviews analyzed by Polygraf. This score is dynamic and changes in real time as new reviews are added.

What does a low or high Polygraf Trust score mean?

Trust scores are calculated from 1-100%. A trust score below 45% means that a review cannot be trusted, one between 45-72% indicates potential issues with trustworthiness & malicious intent, and one above 72% means a review is reliable. A trust score measures the reliability of a review, irrespective of whether it is a positive or negative review. It is not a judgment on the quality of the product or seller.

How do Polygraf Trust EngineI’s reassigned star ratings work?

Polygraf Trust Engine generates and reassigns star ratings at 2 levels: (a) at the individual review level: Current review ratings are subjective and include implicit human bias Our behavioral and sentiment AI protocols holistically analyze each review, considering various parameters, including tone and content. An AI-generated star rating based on NLP is then issued. Here are some examples; a simple statement like "Great company." won't automatically translate to a 5-star review with Polygraf AI's analysis, as it lacks sufficient context. Similarly, there may be a mismatch between the review description and the user-assigned rating. A review like "The directions are really hard to read, but the product quality is excellent and works great." doesn't deserve a 3-star rating. Polygraf’s NLP will address these issues and more, showing a clear correlation between review content and ratings. (a) at the product level: This is an overall star rating that is based on an aggregate of the reviews analyzed by Polygraf AI for a given product that were determined to be reliable (to be considered reliable a review has to have a trust score greater than 72%). It takes into account a variety of opinions analyzed and verified by our AI protocols and provides a simple mathematical average. This rating is dynamic and changes in real time as new reviews are added, giving you the most up-to-date sentiment of the product.

What are Polygraf Trust Engine Seller ratings?

Polygraf Trust Engine studies the reviews across all the products that a seller sells on the e-commerce platform to assign Seller Ratings. For e.g.; if our AI detects seller behavior across the platform that seems suspect, like multiple fake positive reviews, that is reflected in a lower seller rating. Sellers are rated as positive, neutral, or negative visualized by green, orange and red icons respectively.
