On-Line Text Processing: Introduction and Overview.
The objective of the current work program is to develop an on-line computer capability that would assist an information analyst in processing textual materials. The initial result of the work program is the design of a system for text processing and a computer implementation of a preliminary model of the system that strongly supports the validity of the basic design concepts. The model system allows an analyst to scan through messages, reports, and other documents and to identify significant content structures which are processed linguistically and then stored in the computer in a logical form. With respect to a given area of interest the analyst is able to search through the stored content representations, identify those that seem relevant, recover text passages from which they were derived, and edit and annotate these passages to generate reports. The design of the system has two major characteristics: (1)linguistic analysis and logical formalization, (2)man/machine interaction. Developments in transformational grammar provide a formal, mathematical model of language, and elaborations of functional calculus allow for the use of complex predicate-argument structures as content representations. Man/machine interaction is essential because the depth of analysis necessary for representing the information content of text through linguistic and logical techniques cannot yet be wholly mechanized.
