We describe Abstract Meaning Representation (AMR), a semantic representation language in which we are writing down the meanings of thousands of English sentences. We hope that a sembank of simple, whole-sentence semantic structures will spur new work in statistical natural language understanding and generation , like the Penn Treebank encouraged work on(More)
In this paper, we have addressed the task of PropBank annotation of light verb constructions, which like multi-word expressions pose special problems. To arrive at a solution, we have evaluated 3 different possible methods of annotation. The final method involves three passes: (1) manual identification of a light verb construction, (2) annotation based on(More)
This research compares several of the thematic roles of Verb Net (VN) to those of the Linguistic Infrastructure for Interoperable Resources and Systems (LIRICS). The purpose of this comparison is to develop a standard set of thematic roles that would be suited to a variety of natural language processing (NLP) applications. We draw from both resources to(More)
This research focuses on expanding PropBank, a corpus annotated with predicate argument structures, with new predicate types; namely, noun, adjective and complex predicates, such as Light Verb Constructions. This effort is in part inspired by a sister project to PropBank, the Abstract Meaning Representation project, which also attempts to capture " who is(More)
This research discusses preliminary efforts to expand the coverage of the PropBank lexicon to multi-word and idiomatic expressions, such as take one for the team. Given overwhelming numbers of such expressions, an efficient way for increasing coverage is needed. This research discusses an approach to adding multi-word expressions to the PropBank lexicon in(More)
This paper gives guidelines of how to annotate Propbank instances using a dedicated editor, Jubilee. Propbank is a corpus in which the arguments of each verb predicate are annotated with their semantic roles in relation to the predicate. Propbank annotation also requires the choice of a sense ID for each predicate. Jubilee facilitates this annotation(More)
We take the first steps towards augmenting a lexical resource, VerbNet, with probabilistic information about coercive constructions. We focus on CAUSED-MOTION as an example construction occurring with verbs for which it is a typical usage or for which it must be interpreted as extending the event semantics through coercion, which occurs productively and(More)
This research describes SemLink, a comprehensive resource for Natural Language Processing that maps and unifies several high-quality lexical resources: PropBank, VerbNet, FrameNet, and the recently added OntoNotes sense groupings. Each of these resources was created for slightly different purposes, and therefore each carries unique strengths and(More)
This paper gives guidelines of how to create and update Propbank frameset files using a dedicated editor, Cornerstone. Propbank is a corpus in which the arguments of each verb predicate are annotated with their semantic roles in relation to the predicate. Propbank annotation also requires the choice of a sense ID for each predicate. Thus, for each predicate(More)
