The rise of computer graphics offers a new challenge for information retrieval: how to search and -e trie ve information whiih is partly or wholly graphical. As an example, procedures for handling geographical information, such as street maps and directories are explained. With this data, it is possible to find routes on maps, retrieve locations and names of people or businesses, and draw maps. But a comparison jf these programs with programs for face processing or computer typesetting makes clear how far we are fiom general purpose routines. Today successful graphics routines contain a great deal of local domain knowledge. Theie is no analog of the simple keyword systems that handle 'extual documents in any subject area. Just as computational linguists have found that subject matter expertise is necessary to do really sophisticated processing of English, it seems also necessary to sophisticated processing of pictures; the difference is that we don't know how to do unsophisticated processing of graphics.
