Title
(EN) SELECTING POINTS OF INTEREST FOR DISPLAY ON A PERSONALIZED DIGITAL MAP
(FR) SÉLECTION DE POINTS D'INTÉRÊT À AFFICHER SUR UNE CARTE NUMÉRIQUE PERSONNALISÉE
Abstract
(EN)
A system determines a geographic area of interest to be presented to a user in a digital map. The system identifies a set of general POIs based on one or more signals unrelated to the user and, in a first instance, places respective indicators for the set of general POIs on the digital map of the geographic area of interest. In a second instance, the system identifies a set of personalized POIs of likely relevance to the user, based on signals specific to the user and independent of geography, and places respective indicators for the set of personalized POIs on the digital map of the geographic area along with some but not all of the indicators for the set of general POIs, so that density of the indicators does not exceed a certain threshold value.
(FR)
Cette invention concerne un système qui détermine une région géographique d'intérêt à présenter à un utilisateur sur une carte numérique. Le système identifie un ensemble de de points d'intérêt généraux sur la base d'un ou de plusieurs signaux sans rapport avec l'utilisateur et, dans un premier temps, place des indicateurs respectifs pour l'ensemble de points d'intérêt généraux sur la carte numérique de la région géographique d'intérêt. Dans un second temps, le système identifie un ensemble de points d'intérêt personnalisés de pertinence probable pour l'utilisateur, sur la base de signaux spécifiques à l'utilisateur et indépendants de la géographie, et place des indicateurs respectifs pour l'ensemble de points d'intérêt personnalisés sur la carte numérique de la région géographique conjointement avec certains mais pas tous les indicateurs pour l'ensemble de points d'intérêt généraux, de telle sorte que la densité des indicateurs ne dépasse pas une certaine valeur seuil.
