Propriétés des Attributs du Jeu de Données d’Entreprise

Le tableau ci-dessous présente la liste des attributs du jeu de données d’entreprise, avec leur nombre de valeurs distinctes observées pendant l'expérimentation (Values), leur entropie normalisée (Norm. Ent.), leur entropie conditionnelle normalisée minimum (MNCE), leur taux d'identité (Sameness rate), leur taille médiane (Size), et leur temps de collecte médian (Time).

Dans un souci de clarté, nous avons abrégé les noms des objets JavaScript courants et certains appels à des APIs. Nous notons D l'objet JavaScript document, M l'objet Math, N l'objet navigator, S l'objet screen, et W l'objet window. Aussi, nous notons A une instance de Audio Context, AA une instance de AudioAnalyser, et AD l'objet A.destination. Enfin, nous notons WG une instance de WebGL Context, WM le préfixe WG.MAX_, et WI le préfixe WG.IMPLEMENTATION_.

Dû à la diversité des moteurs JavaScript, certaines propriétés sont accessibles au travers de différents appels, comme celles préfixé de moz pour Firefox ou ms pour Internet Explorer. Nous indiquons ces cas via des crochets, et notons A.[B, C] une propriété qui est accessible via A.B ou A.C. Si un seul mot-clef se trouve dans les crochets, ça signifie qu'il est optionnel. Enfin, nous notons [...] une partie qui est omise, mais décrite dans les attributs présentés dans notre article.
