Predicate Argument Structures

In this paper we present a novel, cus- tomizable IE paradigm that takes advan- tage of predicate-argument structures. We also introduce a new way of automatically identifying predicate argument structures, …...

We study the impact of syntactic and shallow semantic information in automatic classifi- cation of questions and answers and answer re-ranking. We define (a) new tree struc- tures based on …...

In this paper, we first compare several strategies to handle the newly proposed three-way Recognizing Textual Entailment (RTE) task. Then we define a new mea- surement for a pair of …...

AbstractWe present a method for acquiring reliable predicate-argument structures from raw corpora for automatic compilation of case frames. Such lexicon compilation requires highly reliable predicate-argument structures to practically contribute to …...

Learning by Reading (LbR) aims at enabling machines to acquire knowledge from and rea- son about textual input. This requires knowl- edge about the domain structure (such as en- tities, …...

Discourse coherence is an important aspect of natural language that is still understudied in computational linguistics. Our aim is to learn factors that constitute coherent discourse from data, with a …...

In this paper, we propose a novel semantic cohesion model. Our model utilizes the predicate- argument structures as soft constraints and plays the role as a reordering model in the …...

We address the challenge of automatically generating questions from topics. We consider that each topic is associated with a body of texts containing useful information about the topic. Questions are …...

AbstractThe identification of various types of relations is a necessary step to allow computers to understand natural language text. In particular, the clarification of relations between predicates and their arguments …...

AbstractThis 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 …...

This article describes a method which al- lows acquiring artifact nouns in French automatically by extracting predicate- argument structures. Two strategies are presented: the supervised strategy and the semi-supervised strategy. …...

Users prefer natural language software re- quirements because of their usability and ac- cessibility. When they describe their wishes for software development, they often provide off-topic information. We therefore present …...

AbstractThis paper presents a new method for learning typed entailment graphs from text. We extract predicate-argument structures from multiple-source news corpora, and compute local distributional similarity scores to learn entailments …...
