Despite the body of research on textbook evaluation from the discourse analysis perspective, cohesive devices have rarely been analyzed in English for Specific Purposes (ESP) textbooks. The acquisition and use of cohesive devices is inherent to naturalistic communication, including business interactions. Hence, L2 learners of business English should be exposed to these devices through cohesion-...

Conversations reflect the existing norms of a language. Previously, we found that utterance lengths in English fictional conversations in books and movies have shortened over a period of 200 years. In this work, we show that this shortening occurs even for a brief period of 3 years (September 2009-December 2012) using 229 million utterances from Twitter. Furthermore, the subset of geographicall...

This study explores the empirical basis for multimodal conversation control acts. Applying conversation analysis as an exploratory approach, we attempt to illuminate the control functions of paralinguistic behaviors in managing multiparty conversation. We contrast our multiparty analysis with an earlier dyadic analysis and, to the extent permitted by our small samples of the corpus, contrast (a...

This paper presents and evaluates several original techniques for the latent classification of biographic attributes such as gender, age and native language, in diverse genres (conversation transcripts, email) and languages (Arabic, English). First, we present a novel partner-sensitive model for extracting biographic attributes in conversations, given the differences in lexical usage and discou...

Conversational spoken language translation (CSLT) systems facilitate bilingual conversations in which the two participants speak different languages. Bilingual conversations provide additional contextual information that can be used to improve the underlying machine translation system. In this paper, we describe a novel translation model adaptation method that anticipates a participant’s respon...

Speech recognition and language analysis of spontaneous speech arising in naturally spoken conversations are becoming the subject of much research. However, there is a shortage of spontaneous speech corpora that are freely available for academics. We therefore undertook the building of a natural conversation speech database, recording over 200 hours of conversations in English by over 600 local...

We describe a translation model adaptation approach for conversational spoken language translation (CSLT), which encourages the use of contextually appropriate translation options from relevant training conversations. Our approach employs a monolingual LDA topic model to derive a similarity measure between the test conversation and the set of training conversations, which is used to bias transl...
