Abstract: According to the embodiments of the present disclosure, a method for conversion evaluation comprises: extracting a resource feature from resource-related data of a target resource; extracting an audience feature of the target audience group from audience-related data of a target audience group of the target resource, the target audience group being to be distributed with a recommended content item related to the target resource; and determining, based on the resource feature and the audience feature, a target predicted conversion rate for the target resource through a predetermined association between resource features, audience features and predicted conversion rates, the target predicted conversion rate indicating a predicted probability of the target audience group performing a conversion for the target resource. According to the scheme, the accuracy of the conversion rate evaluation may be improved, thereby improving distribution effect of the recommended content item for a resource.

Abstract: The present disclosure relates to an interaction method and apparatus, and a device, a computer-readable storage medium and a product. The method comprises: during the process of a live room playing a live video, in response to a change of interaction data in the live room, updating the display of a first progress bar, which is presented in a live video interface and corresponds to a target interaction control; and in response to triggering of the target interaction control, displaying an interaction interface, wherein the interaction interface comprises a virtual resource corresponding to the interaction data.

Abstract: A page display method and apparatus for an application, and an electronic device are provided. The method includes: receiving a play instruction for multimedia content in the application; and in response to the play instruction, in the case that the multimedia content belongs to a preview stream of an online live broadcast, playing the multimedia content and displaying real-time information of the online live broadcast. The real-time information of the online live broadcast includes at least one of a live broadcast commentary or a live broadcast explanation.

Abstract: A method, apparatus, device and storage medium for recommending information. The method includes determining, based on a set of feature representations of a plurality of features associated with information recommendation, a first set of weights indicating importance of the plurality of features. The method also includes determining a second set of weights based on the set of feature representations and the first set of weights. The method further includes recommending the information to a user based on the set of feature representations, the first set of weights and the second set of weights. The importance of respective features associated with the information recommendation can be accurately determined through this method, which further improves the effectiveness of information recommendation and improves the user experience.

Abstract: A magnetic field generator arranged behind a target and for generating a magnetic field on a front surface of the target based on magnetic force lines can include a ring-shaped outer magnetic body having a pole axis in a parallel direction (X-direction) with respect to the target surface, a center magnetic body arranged on an inner side of the outer magnetic body and having a pole axis in a parallel direction (X-direction) with the direction of the pole axis of the outer magnetic body, a yoke plate for supporting the outer magnetic body and the center magnetic body from behind, and a magnetic permeable plate for changing a magnetic field distribution of the front surface of the target. The magnetic permeable plate is arranged so as to be supported by the yoke plate from behind.
