The invention discloses a search method and device for figure information. The search method includes the steps that figure identity information in multiple networks and figure identity corresponding relations are obtained; the figure identity information of the known figure identity corresponding relations is gathered to serve as a training set; an energy minimum model based on the figure behavior similarity degree is constructed, and then energy factors and a matching relation classifier are obtained; energy filling is performed through the energy factors to form an energy matrix, and a matching result predicted at one time is obtained through solving the energy matrix; matching results obtained through repeated solving are integrated, so that the figure identity corresponding relations are obtained, and the identity uniformity of figures with the same name is determined; an input name is received, and the identity information, in different networks, of the same figure is displayed in one webpage. The method and device can determine the uniformity of the information with different identities but the same name in the multiple networks, and the adopted algorithm is efficient and calculation is rapid in the process of displaying the identity information, in different networks, of the same figure in the webpage.
