The term "machine-readable dictionary" can clearly be taken in two ways. In its stronger and better established interpretation, it presumably refers to dictionaries intended for machine consumption and use as in a language processing system of some sort. In a somewhat weaker sense, it has to do with dictionaries intended for human consumption, but through the intermediary of a machine. Ideally, of course, the two enterprises would be conflated, material from a single basic store of lexical information being furnished to different clients in different forms. . | THE DICTIONARY SERVER Martin Kay Intelligent Systems Laboratory Xerox Palo Alto Research Center 3333 Coyote Hill Road Palo Alto California 94304 USA The term machine-readable dictionary can clearly be taken in two ways. In its stronger and better established interpretation it presumably refers to dictionaries intended for machine consumption and use as in a language processing system of some sort. In a somewhat weaker sense it has to do with dictionaries intended for human consumption but through the intermediary of a machine. Ideally of course the two enterprises would be conflated material from a single basic store of lexical information being furnished to different clients in different forms. Such a conflation would if it could be accomplished be beneficial to all parties. Certainly human users could surely benefit from some of the processes that the machine-oriented information in a machine-readable dictionary usually makes available. They can profit even more from other processes specifically oriented to the human user but which have not yet received much attention. For these reasons I believe that machine-readable dictionaries should and probably soon will come to replace traditional book-form dictionaries fairly soon. I do not have in mind machine-readable dictionaries that single users load into their personal machines so much as centralized services to which individual clients subscribe. I have spend a considerable proportion of the last two years designing and implementing a dictionary server. This is a computer with a large dictionary in its file system specifically the American Heritage Dictionary for the use of which we are indebted to its publisher Houghton-Mifflin Company together with a variety for indices for giving rapid access to it. The machine is connected thorugh a packet-switching network to a large number of other computers and work stations. Through a mechanism known as remote procedure call RPC developed concurrently with the dictionary .
