Abstract: The disclosure may provide a method for obtaining a document layout, an electronic device, and a storage medium. The method may include: obtaining a plurality of characters and character information of each of the plurality of characters in a target document; generating a character fully-connected graph based on the plurality of characters and the character information of each of the plurality of characters; obtaining a spatial semantic feature of each of the plurality of characters; generating types of character vertices based on the character information of each of the plurality of characters; generating types of edges based on the spatial semantic feature of each of the plurality of characters, and the character information of each of the plurality of characters; and obtaining a document layout of the target document based on the types of the character vertices and the types of the edges.

Abstract: The present disclosure provides a form information extracting method, apparatus, electronic device and storage medium and relates to the field of artificial intelligence such as natural language processing, computer vision and deep learning. The method includes: for a form to be processed, obtaining feature information of characters in the form, respectively; determining types of the characters respectively and determining a reading order of the characters according to the feature information; extracting a predetermined type of information content from the form according to the types and the reading order of the characters. The solution of the present disclosure may be applied to save the manpower and time costs, and improve the information-extracting efficiency and the accuracy of extraction results.

Abstract: A method of comparing documents, an electronic device, and a readable storage medium are provided, which relate to the field of data processing technology, and specifically to the field of big data technology. In the present disclosure, an area division is performed on each document of two documents to be compared, according to a document layout of each document, so as to obtain at least two sets of comparison units. Each set of comparison units comprises comparison units for the two documents respectively and the comparison units for the two documents correspond to each other. Thus, a content comparison may be performed on between comparison units of each of the at least two sets, so as to obtain a content comparison result for each set of comparison units as a comparison result for the two documents.

Abstract: A method and an apparatus for processing voice data. A specific implementation of the method includes: receiving voice data sent by a user terminal; extracting a voiceprint characteristic vector in the voice data; matching the voiceprint characteristic vector with a registered voiceprint vector prestored by the user, and generating a matching degree between the voiceprint characteristic vector and the registered voiceprint vector; determining whether the matching degree is greater than or equal to a preset update threshold; and updating the registered voiceprint vector by using the voiceprint characteristic vector and the voice data in response to determining that the matching degree is greater than or equal to the preset update threshold. This implementation enhances accuracy of a registered voiceprint vector of a user.

Abstract: The present disclosure discloses a method and an apparatus for authenticating a user. A specific embodiment of the method comprises: receiving an authentication request sent by a user terminal, wherein the authentication request comprises a user identification of a user of the user terminal and operation information related to user operation; determining whether the user operation matches a preset to-be-authenticated operation according to the user identification and the operation information; sending voicing material to the user terminal for reading by the user in response to determining that the user operation matches the preset to-be-authenticated operation, so that the user terminal acquires corresponding authentication voice of the user; receiving the authentication voice sent by the user terminal; and authenticating the user according to the user identification and the authentication voice.
