Graph: spotting the products

Spotting (x, y) coordinates in the graph (x, y) axes of the graph range respectively from 0.5 to 1 (50%-100% similarity with product reference), and from 0 to 5 (worst to best nutrition score). x coordinate The computation of the x coordinate is complex and we just provide here a brief description of it by working with 2 examples: Let P be the product reference shown as an ellipse, and C its number of categories used for computing the similarities between products ( more details... ). Let C = 10, we divide the graph vertically into 10 stripes ( N ) of equal sizes; hence the right-most stripe ranges with x=]0.9; 1]. By the way, this is also the width of the ellipse showing our product reference. So in this stripe are shown all products with a similarity to the product reference of 100%. That being said, a product with a similarity of S=60% will be randomly located in the stripe ]N-1; N] where N = Math.Ceiling(S / (100 / C) = S*C/100 E.g. 1: Let C=10, S=60% => N=Math.Ce...

Graph: how to use the interface?

French version / version française English version The TUTTIFRUTTI website is a web-application fulfilling web-standards and requirements. It can be used on any device (computer, tablet, smartphone) through a web-browser (Mozilla, Chrome, Safari, ...). But you can also create your own App . In this latter case, you can use a barcode scanner to scan products, whereas in a web-browser you may have to type in the barcode manually instead. Note: the above link provides details for creating your App on smartphones running Android . This requires the addition of 2 extra Apps available on the Play Store. If you know similar Apps on the iTunes store, please fell free to contact the author of the blog who will update this news. Be advised: using the application on a device with a mouse (typically a computer) or without a mouse (typically a tablet or smartphone) implies a few differences in the available functionalities. So d...

API usage for getting similar products with scoring

Note: the Prosim Engine delivers matching products with similarity and score details. Check its stats records here. Daily statistics on S C O R E databases are available here . Let P be the product reference (barcode) for which you want to get similar products, C the country and S the store for restricting results, here are the Rest API endpoints delivered by the tuttifrutti.alwaysdata.net website to retrieve this information: Endpoint Parameters Results fetchScoreDbs n/a try it! JSON returned: timestamp of last updates + characteristics of the graphs related to the nutritional Mongo-Databases available on the server (min. and max values for scores, labels for graph, etc.) + statistics on stored data. Typically, it is used by the Statistics link provided at the top of this article. fetchP barcode=P score=R Nu...
