Abstract: An information processing method includes obtaining a conversation record. The conversation record includes a first conversation generated by a first conversation object and a second conversation generated by a second conversation object. The method further includes analyzing the conversation record to obtain at least two question-answer pairs. Each question-answer pair includes the first conversation as a question and the second conversation as a step. The step is a step of a solution corresponding to the question of the question-answer pair. One question corresponds to at least one solution. One solution includes at least one step. The method further includes determining a solution corresponding to each question in the conversation record based on features of the step, and displaying the question and the corresponding solution based on a generation process of the question in the conversation record to obtain a target abstract content of the conversation record.

Abstract: A terminal device sends a directional signal in a direction in which a to-be-controlled device is located, the to-be-controlled device establishes a transmission channel between the to-be-controlled device and the terminal device according to the directional signal, the to-be-controlled device returns a response signal to the terminal device after receiving the directional signal, and the terminal device controls, according to the response signal, an application program corresponding to the to-be-controlled device to start. In this way, a process in which the user uses the terminal device to control the to-be-controlled device, and searches for an application program of the to-be-controlled device is simple, and many application programs do not need to be searched one by one for the required application program.

Abstract: A fingerprint information is collected when a touch screen of a terminal device remains black. Fingerprint recognition is performed. In response to success of the fingerprint recognition, lighting up the touch screen and displaying a first interface. An icon of a first application and a first plurality of application options of the first application are displayed together on the first interface. The first plurality of application options of the first application are displayed in an area within a range of the icon.
