COMPLEX SEMANTIC INFORMATION PROCESSING

In this paper some recent results from linguistics, cognitive psychology and artificial intelligence will be applied in the formulation of some major problems of information science.* These results pertain to theories about the structure and processing of discourse and of complex semantic information in particular. It is argued that grammatical and other models of discourse constitute a necessary basis for a sound theoretical explication of such terms as 'content of a text (or document)', 'abstract' or 'summary', 'key-word', 'paraphrase', 'theme' or 'topic', etc., as they are used in information science. In this respect the current automatic or non-automatic approaches to the analysis and processing of texts in documentation are found to be inadequate, whatever their practical merits may be.
