Semantic Role Labelling of Prepositional Phrases
نویسندگان
چکیده
We propose a method for labelling prepositional phrases according to two different semantic role classifications, as contained in the Penn treebank and the CoNLL 2004 Semantic Role Labelling data set. Our results illustrate the difficulties in determining preposition semantics, but also demonstrate the potential for PP semantic role labelling to improve the performance of a holistic semantic role labelling system.

Prepositional phrases (PPs) are both common and semantically varied in open English text. Learning the semantics of prepositions is not a trivial task in general. It may seem that the semantics of a given PP can be predicted with reasonable reliability independent of its context. However, it is actually common for prepositions or even identical PPs to exhibit a wide range of semantic fuctions i...
متن کاملJoint Learning of Preposition Senses and Semantic Roles of Prepositional Phrases
The sense of a preposition is related to the semantics of its dominating prepositional phrase. Knowing the sense of a preposition could help to correctly classify the semantic role of the dominating prepositional phrase and vice versa. In this paper, we propose a joint probabilistic model for word sense disambiguation of prepositions and semantic role labeling of prepositional phrases. Our expe...
متن کاملIntegration of Semantic and Syntactic Constraints for Structural Noun Phrase Disambiguation
A fundamental problem in Natural Language Processing is the integration of syntactic and semantic constraints. In this paper we describe a new approach for the integration of syntactic and semantic constraints which takes advantage of a learned memory model. Our model combines localist representations for the integration of constraints and distributed representations for learning semantic const...
متن کاملCFN - based Semantic Role Labeling of Chinese Prepositional Phrase ⋆
Prepositional Phrases are often among the most frequent expressions in Chinese, but they have been ignored on the grounds of being syntactically promiscuous and semantically vacuous, and relegated to the ignominious rank of “stop word”. The Chinese FrameNet (CFN) is a lexical resource project developed by Shanxi University, Taiyuan, based on the principles of Frame Semantics and supported by co...
متن کاملOntology-Based Semantics for Prepositions
This paper addresses the elaboration of a relation-logical compositional semantics for the meaning content of nominals using formal ontologies as semantic domains. Prepositions are conceived as denoting binary semantic role relations between concepts in the ontology. The ontology comes with ontological affinities specifying the admissible ontological combinations. The key idea is to establish a...
