In this paper we explore a new theory of discourse structure that stresses the role of purpose and processing in discourse. In this theory, discourse structure is composed of three separate but interrelated components: the structure of the sequence of utterances (called the linguistic structure), a structure of purposes (called the intentional structure), and the state of focus of attention (ca...

According to discourse theories in linguistics, conversational utterances possess an informational structure that partitions each sentence into two portions: a “given” and “new”. In this work, we explore this idea by building sub-sentence discourse language models for conversational speech recognition. The internal sentence structure is captured in statistical language modeling by training mult...

Sentence compression holds promise for many applications ranging from summarisation to subtitle generation. The task is typically performed on isolated sentences without taking the surrounding context into account, even though most applications would operate over entire documents. In this paper we present a discourse informed model which is capable of producing document compressions that are co...

Sentence compression holds promise for many applications ranging from summarization to subtitle generation. The task is typically performed on isolated sentences without taking the surrounding context into account, even though most applications would operate over entire documents. In this article we present a discourse-informed model which is capable of producing document compressions that are ...

Theories of CSCL have often focused on the discourse of student groups and their possible modes of participation in this discourse as definitive of collaborative learning. Lave & Wenger (1991), for instance, analyzed the increasing participation of novices in the discourses of communities of practice. Scardamalia & Bereiter (1996) proposed the use of networked computers to promote literate part...

Ecolinguistics: language and ecology delivers an overall view and a critical approach on ecolinguistic studies. This book is an excellent resource to students, researchers, linguists and those working in the area of discourse analysis as well as ecology. The book claims presenting a news course for ecolinguistics including a framework for understanding the theory of ecolinguistics, exploration ...

Discourse parsing aims to identify the relationship between different discourse units, where most previous works focus on recovering the constituency structure among discourse units with carefully designed features. In this paper, we propose to exploit Long Short Term Memory (LSTM) to properly represent discourse units, while using as few feature engineering as possible. Our transition based pa...
