Abstract: A web content enrichment system can match an image to text of web content. When the text of web content includes a snippet, the image matched to the text enriches the snippet to enhance results of a search engine. When the text of web content includes text contained in a webpage, the image matched to this text enriches the webpage to enhance user perception and understanding of the webpage. The process of matching images to text involves extracting features of a plurality of images and features of a plurality of text documents, calculating scores of the images based on the extracted features, and selecting one image per text document based on the scores using a machine-learning algorithm. The result of the matching can be provided to a web content module for storing, incorporating into the result lists of the search engine, or delivery to a user.
