A drawing information presentation apparatus has a memory for storing data representing a plurality of drawings, including text labels, and a concept dictionary memory for storing synonyms and connection relation for terms used in the text labels. A correspondence analysis section analyzes correspondence relation of elements of two drawings by referring to data of the concept dictionary memory. Then, a display section displays elements of a first drawing in a manner which demonstrates those elements of the first drawing which correspond to elements of the second drawing, from those elements of the first drawing which do not so correspond, in accordance with the analysis performed by the correspondence analysis section. The apparatus also comprises a drawing description analysis section for extracting drawing titles from document information, and for analyzing the correspondence relationship of the drawing titles between two drawings, by referring to date of the concept dictionary memory. In this case, the correspondence analysis section analyzes the correspondence relationships of elements between two drawings, whose titles are analyzed to correspond to each other by the drawing description analysis section.
