The similarity and diversity of semantic relations

Subjects’ perceptions of similarities among relations were studied for a wider variety of relations than had been used in previous studies, and relations were viewed not as unanalyzable primitives, but in terms of the relational properties that distinguished them.

Abstract

There is a rich variety of semantic relations in natural languages. Subjects' perceptions of similarities among relations were studied for a wider variety of relations than had been used in previous studies. Forty subjects sorted 31 cards bearing five example pairs of each of 31 semantic relations. Subjects were able both to distinguish the relations and to perceive their similarities. A hierarchical clustering analysis of the sorting data indicated that the subjects perceived five families of semantic relations (contrasts, class inclusion, similars, case relations, and part-wholes). The five families were distinguished in terms of three properties of semantic relations: contrasting/noncontrasting, logical/pragmatic, and inclusion/noninclusion. Within each family, relations also were sorted in ways consistent with their defining properties. Relations were therefore viewed not as unanalyzable primitives, but in terms of the relational properties that distinguished them.
