Abstract: Embodiments of the present disclosure relate to a method and apparatus for generating a text description for an image, an electronic device, and a medium. The method includes generating a first feature of the image through a visual encoder, where a text encoder semantically aligned with the visual encoder is used to train a conversion model and a language model. The method further includes converting the first feature into a second feature through the conversion model, where the first feature and the second feature correspond to different feature spaces. In addition, the method also includes generating, by the language model, a text description for the image based on the second feature.

Abstract: Embodiments of the present disclosure disclose a method and an apparatus for generating video dialog question answering data, an electronic device, and a medium. The method includes: determining target video description information corresponding to a target video; determining a target prompt used for a target question answering model, where the target question answering model is pre-configured based on a large language model, and the target prompt is capable of guiding the target question answering model to a desired dialog question answering effect based on the target video description information when the target question answering model executes a dialog question answering generation task; and outputting, using the target question answering model and based on the target video description information and the target prompt, dialog question answering data associated with the target video.

Abstract: The invention relates to a class of novel Brønsted acidic ionic liquids each having a lactam cation, and to a method for preparing the same through simple neutralization reaction of a lactam, which is available in large scale from industry, with a Brønsted inorganic or organic acid under room temperature. The properties of the lactam Brønsted acidic ionic liquids are as follows: they are water- and moisture-stable; they are more environmentally benign and lower cost than that of dialkylimidazolium salts; they have stronger Brønsted acidity and can be used as acidic catalysts and media instead of inorganic corrosive acids, such as concentrated sulfuric acid and hydrofluoric acid, in many acid-catalyzed reactions; and they can also be used as green media for extraction and separation.
