  • Patent number: 10019734
    Abstract: Embodiments of the present invention are directed to flexible, user-adapted, continuous searching, on behalf of a particular user, for points of interest relevant to the user's current location within a specifically computed personal region of interest. In a general case, the personal region of interest is computed as a function of the user's level of disposition towards the searched-for points of interest. The level of disposition towards the searched-for points of interest may, in turn, be based on two or more of the user's location, the current date and time, a history of the user's interaction with the POI-searching system, including user-initiated searches and user selections from displayed search results, a user profile developed for, and continuously updated on behalf of, the user, and a current context for the search, as specified by a search query or by other context-specifying means.
