Refining the frame element hierarchy: Application of initial steps

Several proposed steps for refining the frame element hierarchy have now been performed. At present, there are 1011 frame elements in the frame element digraph with 261 primitives (compared with an original 476 primitives), consisting of 202 primitives not used as hypernyms and 59 used as hypernyms in deriving 750 frame elements. The current hierarchy […]

Circularities in the frame element hierarchy

In a digraph analysis, links between nodes may give rise to strong components, i.e., nodes that are mutually reachable. In the frame element hierarchy, ten strong components (or circularities) have arisen. In an effort to provide a strict hierarchy for frame elements, these circularities need to be broken. In doing this, it is instructive to […]

Preposition meaning: syntactic reflex and semantic relation coverage

The Oxford Dictionary of English defines preposition as “a word governing, and usually preceding, a noun or pronoun and expressing a relation to another word or element in the clause”.  A few years ago, Bill Dolan, quoting Lucy Vanderwende (both of the Microsoft NLP group), suggested that prepositions are essentially just syntactic reflexes that have […]

Analyzing the frame element digraph: Initial steps

The main objectives of analyzing the frame element digraph, whose derivation was described in a previous post, are to identify the primitive frame elements and to show the derivational hierarchy of each of the other frame elements.  There are 1015 frame elements in the frame element dictionary. Based on the hypernym relationships, this yields a […]
