The most difficult and important research questions for the advancement of general-purpose language processors are seen to be concerned with measuring meaning, dealing with ambiguities, translating into formal languages and searching large tree structures. DOI in [ACM] CACM 8(01) Jan 1965 view details in [ACM] CACM 8(01) Jan 1965 view details Three search languages are analyzed in detail and compared on the basis of form and capability. The selected languages are: QUERY, used in the context information processing system; the Relational Language. based upon early work with a Relational Data File at Rand Corporation; and TDMS, a state- of the-art file management system developed at SDC. The complete language structures are not described; only certain features are selected for comparison. Within this limitation, the comparisons are handled in a reasonable, straight-forward manner and with the aid of many examples. In effect this report reviews the thinking of the authors as they studied different search languages and justified the need to design the new language QUERY for use in the context retrieval system and to plan for needed extensions of this language. in ACM Computing Reviews 11(02) February 1970 view details in [ACM] ACM Computing Surveys (CSUR) 8(1) March 1976 view details |
