Lesk Harvard University Gerard Salton Use, reproduction, or publication, in whole or in part, is permitted for any purpose of the United States Government. 11-20 proceeds to the next set after finishing the present run, instead of returning control to the monitor system; PA[OCRerr] n this specification sets the initial page nuiiber to n. The normal setting is n = 1; STOP or X these synonymous specifications both indicate the end of the specification list. One of the two should be the last specification on the input cards; neither should occur any- where else in the specification list. A summary of the specifications is given in Table 2. [OCRerr]. Data Input After the specifications are submitted, the user m'ist provide the data for the retrieval processing. This consists of requests, documents, and relevance jud[OCRerr]ents, in a typical run. They may be introduced in either [OCRerr]glish or in looked-up binary form, and documents may be introduced on A2, A6 or both. Documents are divided into three ategories, the requests, the texts (documents to be searched), and requests which are also texts. This last category consists of documents to be used as search requests, but which may also appear as answers to other search requests (normally, requests may not appear as answers to other requests). The last named document type might occur if a user has identified one document in his field of interest and wishes to see more documents on the same subject. All of these types mly occur in natural language; in binary form, or both. 4.1. Natural Langage Documents Natural language input must be submitted before binary-form documents.
