Annotating Syntax and Lexical Semantics With(out) Indexing

A new method of annotation is introduced that is able to establish a rich range of dependencies without recourse to indexing. With well defined annotation practices for assigning structure, the index-less annotation can be subsequently processed by means of a mechanism of semantic calculation that identifies relationships (dependencies) by reference to structure. These relationships can be subsequently expressed through a derived indexing, but don't rely on indexing in order to be established. The technique is illustrated capturing dependencies seen with PropBank/FrameNet annotations.
