Abstract: Embodiments herein provide a method and device for analyzing a social relationship. The method includes: acquiring at least one target interaction parameter pertaining to an interaction between the first electronic device and a second electronic device; and determining a ranking value of a social relationship between a first user of the first electronic device and a second user of the second electronic device according to the at least one target interaction parameter.

Abstract: An unlocking method for use in a terminal having a touch screen, includes: detecting a touch signal corresponding to a touch movement on the screen in a moving direction; and triggering the terminal to enter into an unlocked state, if the moving direction is the same as a preset reference direction and a number of loops of the touch movement corresponding to the touch signal is the same as a preset reference number of loops, wherein the preset reference direction is one of a clockwise direction or an anticlockwise direction.

Abstract: Method and device for data search are provided. The method includes: retrieving a first serialized data corresponding to a first user identifier in a non-relational database; deserializing the first serialized data to obtain a first index; performing a search based on the first index. In the embodiments of the present disclosure, serialized data corresponding to a user identifier may be retrieved and deserialized into an index by a server in a NoSQL database and a search may be performed based on the index. Since the search is performed against data corresponding to user identifiers rather than all users, a much smaller search scope is covered, leading to an improved search speed and performance and optimized user experience.

Abstract: This disclosure discloses a method and device for managing a user interface. The user interface can display one of a multiple of layers, which may share one or more same icons of available application programs. Users can change the layer being displayed on the user interface through performing a simple touch gesture on the touch screen, thereby quickly finding out a set of application programs needed to use currently. Thus, users' operations are simplified.

Abstract: A method for a first terminal device to handle a busy line is provided. The method includes: sending a number query request when a second terminal device to which the first terminal device initiates a first call request is in a busy state; receiving a feedback on the number query request, wherein the feedback is provided based on a second call request initiated by the second terminal device; and if the feedback indicates that the second terminal device is calling the first terminal device, sending a connecting request to a server or sending a terminating request to one of the server and the second terminal device, wherein the connecting request indicates a request to connect the first terminal device with the second terminal device, and the terminating request indicates a request to terminate the second call request initiated by the second terminal device.

Abstract: The present disclosure discloses a method for displaying messages in a terminal device and the terminal device thereof. The method includes the following steps: displaying messages by a display; detecting a first preset gesture acting on the display, wherein the gesture generates two endpoints on the display; and adjusting messages between the two endpoints. Accordingly, it is very convenient for the user to adjust the displayed messages by performing a simple gesture on the display of the terminal device.

Abstract: A method for a device to display a message includes receiving a message marking instruction directed to a message in a message display window; processing the message according to the message marking instruction; and updating the message display window with the processed message.

Abstract: A method for processing includes detecting a gesture operation to a session in a current session interface, determining whether the gesture operation is identified, and performing a corresponding processing to the session in the current session interface according to the gesture operation if the gesture operation is identified.
