Abstract
Embodiments of the present invention disclose a method and apparatus of generating an image characteristic representation of a query, and an image search method and apparatus. The method of generating an image characteristic representation of a query comprises: acquiring a clicked image set corresponding to a target query based on an image click log of a search user; generating image characteristic vectors corresponding to clicked images in the clicked image set based on image content characteristics of the clicked images; and clustering the clicked images based on the image characteristic vectors, and using a clustering result as an image characteristic representation of the target query.
