Κάθε φορά που ανεβάζετε μια φωτογραφία στο Facebook ή σε κάποια άλλη από τις υπηρεσίες της εταιρείας, προστίθενται αυτόματα ετικέτες ή tags. Ένας από τους λόγους για αυτή την προσθήκη είναι ότι τα tags μπορούν να βοηθήσουν τα άτομα με προβλήματα όρασης να κατανοήσουν photos posted on Facebook (according to the company).
But the fact shows how much the algorithm has developed on Facebook. Needless to say, each tag or tag is automatically added to the bigger social networking data.
And while the algorithm recognitionς εικόνων του Faceboοk συνεχίζει να εξελίσσεται για να βελτιώσει τις υπάρχουσες υπηρεσίες, όπως την αναζήτηση ή το να διασφαλίσει ότι οι εικόνες δεν παραβιάζουν τις πολιτικές του κοινωνικού δικτύου, μπορεί και να προσθέσει information which is not part of the image metadata.
The algorithm that analyzes images in Facebook adds more basic tags like sky, tree, cat, and other words that define the image.
Since April 2016, Facebook automatically adds alt tags to the images you upload so they are filled with keywords that represent the content of your images. Labeling of your images is done by Deep ConvNet developed by team Facebook FAIR.
If you're interested in learning how and which labels Facebook adds to your photos, you can install a browser add-on that reveals them.
The Show Facebook Computer Vision Tags is a browser add-on for him Chrome and Firefox. After installation all you need to do is visit Facebook. You will notice that in the photos that are in the social network you also see the labels in the upper right corner.
Tags are only in the photos uploaded by someone and not in the images added with a link.
The images you see and do not have labels are because Facebook's image recognition algorithm has had trouble locating the image.
It seems that the algorithm does not work properly for all the images and definitely keeps Facebook's technicians busy. But as you will notice, he does his work for most of the photos on the website.
