The construction of knowledge bases with morphological semantics

This paper presents a strategy for building a morphological machine dictionary of English efficiently to infer meanings of derivatives from a simple word (semantic stem) by considering morphological affixes and their semantic classifications. The basic concept is to group the derivatives into one frame and to restrict the derivatives, accessible to a knowledge base, to the semantic stem. This approach enables us to simplify the structures of a morphological dictionary and the representation of the knowledge base. An efficient retrieval algorithm for these representation is presented by a modified hash technique
