ISR11 Operating Instructions for the SMART Text Processing and Document Retrieval System chapter M. E. Lesk Harvard University Gerard Salton Use, reproduction, or publication, in whole or in part, is permitted for any purpose of the United States Government. 11-11 value, i.e. they nuist be assigned the proper word stem or the proper thesaurus category; 2) the components of the phrase miist have the proper syntactic role (e.g. "aut[OCRerr]natically translating" would not match "aut[OCRerr]natic translation"); 3) the components of the phrase zinist exhibit the proper syntactic dependency relations with each other (e.g. "blind Venetian" would not match "Venetian blind"). This phrase searching procedure makes use of the Kuno multiple-path syntactic analyzer (7,8,9] to determine the syntactic roles and dependency relations of the words in the sentence. This makes possible very accurate searching, in that, for exan[OCRerr]le the phrase "solid state" would not be recognized as appearing in "Some authors [OCRerr][OCRerr]hose other work is solid state that information retrieval can be performed without accurate syntactic analysis." It should be noted that the syntactic phrase searcher is very slow and also very erratic in its tinzing. It is hoped that the use of a new version of the Kuno syntactic analyzer will alleviate these problems (10]. The specifications to be used in the phrase searching procedure are: which causes a statistical phrase search to be performed; which causes a syntactic phrase search to be performed; causes a table of the detailed correspondences between tree nodes and sentence words to be printed; SYNA[OCRerr][OCRerr] causes the syntactic analyses of the text searched to be printed.
