Most recent annotation efforts for language have focused on small pieces of the larger problem of semantic annotation, rather than producing a single unified representation. In this talk, I investigate the issues involved in merging several of these efforts into a unified linguistic structure: specifically, PropBank, NomBank, TimeBank, Discourse Treebank, and Opinion Corpus. Each of these is focused on a specific aspect of the semantic representation task: semantic role labeling, discourse relations, temporal relations, etc., and has reached a level of maturity that warrants a concerted effort to merge them into a single, unified representation, what I will refer to as a Unified Linguistic Annotation (ULA). There are several technical and theoretical issues that must be resolved to bring these different layers together seamlessly. Most of these approaches have annotated the same type of data (Wall Street Journal), so it is also important to demonstrate that the annotation can be extended to other genres such as spoken language. The demonstration of success for the extensions is the training of accurate statistical semantic taggers
