Abstract : The algorithmization of an inversion-type information retrieval system (IRS) with the object of utilizing it in electronic computers is described and the advantages of the coordinate-comparison retrieval method over the sequential retrieval method are pointed out, particularly with respect to bulky documents for the purpose of assuring the flow of documents to users without great effort on their part as well as of eliminating manual labor and accelerating the retrieval process. In addition, the authors form the class of standard processes into which the algorithm of the inversion-type IRS breaks down; this class may be utilized in the solution of other information-logic problems. The developed algorithm flowchart of the IRS corresponds to the special features of electronic digital computers and may serve as a basis for developing a practical and convenient information retrieval system. The findings of the experiments with the realization of an inversion-type IRS by means of Ural-2 electronic digital computers also are presented.
