Abstract

The invention relates to an information extraction method and device, electronic equipment and a storage medium, relates to the technical field of information processing, and aims to solve the problems that object meta-information is complex, lack of pertinence and cannot be accurately and efficiently applied in the related art, and the method comprises the following steps: obtaining a label set corresponding to a target object and account information of a target account, wherein the label set comprises at least two labels used for describing objects; based on a preset mapping mode, obtainingattention features obtained through mapping according to the account information, wherein the attention features comprise weights corresponding to all tags in the tag set, and the preset mapping modeis determined according to historical behaviors of sample objects corresponding to the sample accounts; and determining target object meta-information corresponding to the target account according tothe attention features and the label set. According to the embodiment of the invention, the attention characteristics associated with the user can be obtained, the attention of the user to each labelin the label set can be represented, and the target object can be described in a targeted manner.

Description

technical field [0001] The present disclosure relates to the technical field of information processing, and in particular to an information extraction method, device, electronic equipment, and storage medium. Background technique [0002] With the rapid development of science and technology, deep learning has been widely used in video images, speech recognition, natural language processing and other related fields. As an important branch of deep learning, convolutional neural network (CNN) has greatly improved the prediction accuracy of image classification tasks due to its strong fitting ability and end-to-end global optimization ability. [0003] Although the accuracy of the model has been greatly improved, it has a certain limit with normal usage scenarios. Due to the large number of feature dimensions perceived by the algorithm, it is difficult to describe the video in a more targeted manner and apply it to specific scenarios. For example, in the search scenario, the u...
