Argues that tables, graphs, and diagrams extend language's power by exploiting the Euclidean possibilities which a text suggests. Notes that graphic display elements form no compatible natural set and that their value and visual elements are decisively disparate. Concludes that graphic displays are unlikely candidates for unitary theoretical…

Discusses knowledge graphs, a new form of knowledge representation, and their possible uses in electronic study books. Topics addressed include graph structures; semantics; and representing knowledge from books, including browsing, information marking, annotations, group-based learning, information sequencing, information distribution, and…

Discusses the use of logical imaging in information retrieval. Topics include the use of nonclassical logic in information retrieval; imaging and possible worlds semantics; retrieval by imaging; evaluation processes; worlds mass and worlds distance; and future work. (LRW)

Describes the logical construction of several Russian hypertext systems, and discusses the navigational algorithms used, nodes selected, and coherence demanded. Several illustrative graphs are included, and an overview of the development of linking structures producing logical-semantic models is given. (20 references) (EA)

Presents the ALEXIA system, a lexical-learning environment for French as a second or foreign language, and describes its network module, which can automatically build graphs of certain lexical semantic relations. (Author/VWL)
