Presents the "Evidence-of-Existence" information system in which the structure is developed, with application of cybernetic concepts, as an isomorphic model in analogy to the system structure of communication technology. Three criteria of structuring are postulated: (1) source-channel-sink, with input-output characteristics, (2) filter-type…

Defines a "communicate"--the objectification of a subject's internal model of the object of reality by means of a certain set of physical signs--and examines its information value with relation to intelligent systems. (CWM)

Examines the selective dissemination of indexed surrogates to overcome two major causes of cultural lag: reading overload and lack of cogency of technical communication. An analysis of three models--reference-retrieval systems, question-answering systems, and surrogate-dissemination systems--explores reasons for lag in technique implementation.…

Describes a semantic content recognition process based on relatively small sets of context relators, logical relators, phase and state relators, and aspect relators, which are connecting tools in describing meanings in process of concept formation and human communication. Semantic analysis of textual data by computer is tested for feasibility.…

Presents a system model for transmission of input data that is coming from terminals of users in a limited user resource-sharing environment. Performance of a mini/microcomputer receiving mixture of picture-phone terminal data is analyzed with constant service times, synchronous transmission, and single-server interruptions through first-order…
