An apparatus and method for searching color and shape of image data based on a natural language with Fuzzy concept is disclosed. The apparatus for retrieving includes: a dictionary storing unit for storing a dictionary used for processing a natural language; a color/shape threshold storing unit for storing color histograms mapped to color related words and edge information corresponding to shape related words; a query input unit for receiving a query sentence which describes the color and the shape of the image by using a natural language; an analyzing unit for analyzing the query sentence based on the dictionary information and generating analyzed words; a color/shape recognizing unit for recognizing whether the analyzed words represent the color or the shape; a color/shape threshold database constructing unit for mapping and storing color histograms to color related words and storing edge information corresponding to shape related words; a color/shape threshold retrieving unit for retrieving the color histograms and the edge information corresponding to the analyzed words from the color/shape threshold storing unit; and a retrieving result output unit for providing image data searched in the color/shape threshold retrieving unit.
