Abstract: An adaptive discussion-topic system, an operating method thereof, and a non-transitory computer-readable recording medium are provided. The adaptive discussion-topic system includes a server having a discussion-topic database and a software program executed in a user device for initiating a graphical user interface. When the server receives a selection of one of discussion-topic categories displayed on a first layer discussion-topic page, the discussion-topic database is queried for rendering a second layer discussion-topic page. The second layer discussion-topic page is displayed on the graphical user interface initiated by the user device, in which multiple discussion-topic areas are displayed in a first direction, and multiple discussion-topic areas associated with a location attribute or multiple discussion-topic categories that relate to topics of the discussion-topic areas in the first direction and match with a personal preference of a user are displayed in a second direction.

Abstract: A location-related topic discussion system, an operating method, and a computer-readable recording medium are provided. The system includes a server having a topic-discussion database. In the server, the topic-discussion database is queried for obtaining one or more location-related discussion topics within a geographic range according to location information transmitted by a user device. The server then provides one or more location-related discussion-topic-category linking icons to the user device, and the one or more icons can be marked on a graphical user interface initiated by the user device. When a user selects one of location-related discussion-topic-category links, the server accordingly provides contents on a first layer topic-discussion page to be displayed by the user device. The first layer topic-discussion page includes multiple popularity-sorted topic-discussion areas and location-related discussion topic categories in accordance with personal preference of the user.

Abstract: A method and a system for providing contents within a region of interest of a user are provided. The system includes a serving system having a database, and an application program executed in a user device. The application program is configured to initiate a user interface for allowing the user to browse the one or more contents within the region of interest. The serving system receives an instruction that is generated when the user clicks a link to enter the region of interest via the user interface. The database is queried according to one or more regions of interest of the user in a user regional activity profile, so as to obtain the contents within every region of interest. Lastly, the serving system provides links associated with the one or more contents to the user device, and the links can be displayed on the user interface.
