摘要： A method for retrieving an image is provided. The method comprises: acquiring a first matrix obtained by performing feature extraction on a sketch of a target item; acquiring a second matrix composed of word vectors of keywords in a keyword set corresponding to the target item; acquiring a third matrix set obtained by performing feature extractions on images in an image set respectively; determining, for a third matrix in the third matrix set, a comprehensive matching degree between an item presented in an image corresponding to the third matrix and the target item, based on a first matching degree between the first matrix and the third matrix and a second matching degree between the second matrix and the third matrix; and selecting a preset number of images from the image set based on the determined comprehensive matching degrees, and sending the selected images.
