References: Extract: The approach to a solution The approach to a solution In the last few years there has been an increasing interest in general programming systems which attempt to solve this problem by providing some special language or program which takes advantage of the basic similarity of all tasks which consist of extracting and presenting data. Within this broad classification we can however define two main divisions. These we may call Technical Information Retrieval (TIR) exemplified by the retrieval of relevant abstracts from scientific journals and Management Information Retrieval (MIR) exemplified by sales analyses. Table 1 displays the difference between the two types of retrieval situation. A typical TIR request might be: 'Print the complete abstracts of any article written in 1969 and appearing in the Operational Research Quarterly or the Journal of the 0. R. Society of America which deals with the use of simulation or model building in marketing or with the implementation of marketing models, but excluding any article written by J. Smith or any article referring to Dynamic Programming Techniques.' A typical MIR request: 'Print the customer, product, date, sales reference number and value of all invoices with a value of less than £10 for product group X, area Y, during May. Compute the gross margin as a percentage of invoice value and print this next to the value. Sequence the results by date within product within customer and give totals of values and average of gross margin on change of customer or product.' Although most information retrieval programming systems are capable of work in both areas, the impetus for their creation has usually come from one in particular. FIND (I.C.L., 1966) and SPECOL (Smith, 1968), for example, are aimed primarily at Technical Information Retrieval. Systems directed at Management Information Retrieval include NITA and FILETAB (N.C.C., 1969), CRESTS (Craig, 1966), the Sales Management Information Retrieval System of the Metal Box Company (Gearing, Reynolds & Sears, 1968) and all R.P.G.
