In this paper, we introduce a new framework for recognizing textual entailment (RTE) which depends on extraction of the set of publicly-held beliefs – known as discourse commitments – that can be ascribed to the author of a text (t) or a hypothesis (h). We show that once a set of commitments have been extracted from a t-h pair, the task of recognizing textual entailment is reduced to the identi...

Texts are commonly interpreted based on the entire discourse in which they are situated. Discourse processing has been shown useful for inference-based application; yet, most systems for textual entailment – a generic paradigm for applied inference – have only addressed discourse considerations via off-the-shelf coreference resolvers. In this paper we explore various discourse aspects in entail...

In this paper, we present our work on constructing a textual semantic relation corpus by making use of an existing treebank annotated with discourse relations. We extract adjacent text span pairs and group them into six categories according to the different discourse relations between them. After that, we present the details of our annotation scheme, which includes six textual semantic relation...

In order to produce coherent linear documents, Natural Language Generation (NLG) systems have traditionally exploited the structuring role played by textual discourse markers such as relational and referential phrases. However, these coherence markers of the traditional notion of text do not work as efficiently in non-linear informative documents, where ambiguity and indeterminacy are usually u...

In this paper I introduce computational techniques to extend qualitative analysis into the study of large textual datasets. I demonstrate these techniques by using probabilistic topic modeling to analyze a broad sample of 14,952 documents published in major American newspapers from 1980 through 2012. I show how computational data mining techniques can identify and evaluate the significance of q...

Resumen. En este artículo describimos nuestro enfoque para la asignación de sintaxis concreta tanto gráfica como textual a Lenguajes Específicos de Dominio (LEDs). Nuestra aproximación consiste en definir un meta-modelo que describe la sintaxis abstracta del LED, a cuyos elementos se puede asignar una visualización gráfica. Para asignarles una sintaxis textual se ha construido un meta-modelo co...

This study proposes a computational model of the discourse segments in lyrics to understand and to model the structure of lyrics. To test our hypothesis that discourse segmentations in lyrics strongly correlate with repeated patterns, we conduct the first large-scale corpus study on discourse segments in lyrics. Next, we propose the task to automatically identify segment boundaries in lyrics an...

Academic writing is not just about presenting a set of ideas, but through the act of writing, the authors position themselves as individuals having particular identities which mostly reflect the dominant sociocultural values and practices of the discourse communities in which they are living and performing. The present study, using a mixed method approach, attempted to explore the evidences of ...
