Abstract: The present disclosure provides a method for visual question answering, which relates to fields of computer vision and natural language processing. The method includes: acquiring an input image and an input question; detecting visual information and position information of each of at least one text region in the input image; determining semantic information and attribute information of each of the at least one text region based on the visual information and the position information; determining a global feature of the input image based on the visual information, the position information, the semantic information, and the attribute information; determining a question feature based on the input question; and generating a predicted answer for the input image and the input question based on the global feature and the question feature. The present disclosure further provides a device for visual question answering, a computer device and a medium.

Abstract: The disclosure provides a method and an apparatus for extracting content from a document, an electronic device, and a storage medium, which relates to the field of artificial intelligence (AI) technologies such as natural language processing (NLP), deep learning (DL), knowledge graph (KG). The detailed implementation scheme is: obtaining the document; performing anchor search on the document to obtain anchor information corresponding to the document; determining region information of content to be extracted based on the anchor information; and extracting the content to be extracted from the document based on the region information.
