In this paper, we propose a bilingual lexical cohesion trigger model to capture lexical cohesion for document-level machine translation. We integrate the model into hierarchical phrase-based machine translation and achieve an absolute improvement of 0.85 BLEU points on average over the baseline on NIST Chinese-English test sets.

Transcript-based topic segmentation of TV programs faces several difficulties arising from transcription errors, from the presence of potentially short segments and from the limited number of word repetitions to enforce lexical cohesion, i.e., lexical relations that exist within a text to provide a certain unity. To overcome these problems, we extend a probabilistic measure of lexical cohesion ...

Anomic aphasia is a disturbance affecting lexical retrieval. Nonetheless, persons with this disorder may also experience difficulties in the construction of coherent narratives. Whether this symptom is a sign of a macrolinguistic difficulty per se or reflects the lexical disorder is still an open debate. In order to analyze the effect of the lexical impairment on macrolinguistic processing, we ...

An analysis of linguistic approaches to determining the lexical cohesion in text reveals differences in the types of lexical semantic relations (term relationships) that contribute to the continuity of lexical meaning in the text. Differences were also found in how these lexical relations join words together, sometimes with grammatical relations, to form larger groups of related words that some...

Automatic text summarization takes an input text and extracts the most important content in the text. Determining the importance of information depends on several factors. In this paper, we combine two different approaches that have been used in the text summarization domain. The first one is using genetic algorithms to learn the patterns in the documents that lead to the summaries. The other o...

This paper uses materials from annotation studies of lexical cohesion (Beigman Klebanov and Shamir, 2005) and of definite reference (Poesio and Vieira, 1998; Vieira, 1998) to discuss the complementary nature of the two processes. Juxtaposing the two kinds of annotation provides a unique perspective for observing the workings of the reader’s common-sense knowledge at two levels of text organizat...

This paper presents research that connects the cohesion structure of a text to the derivation of its coherence structure. Two diierent algorithms that derive the cohesion structure in the form of lexical paths from large thesauri are illustrated. Their results are correlated with (1) cue phrases of discourse usage and (2) coherence constraints empirically derived. A novel model of coherence str...

In this paper, we introduce the notion of speech cohesion for topic segmentation of a spoken content. The aim is to integrate speaker information and lexical information within a single cohesion value. Based on a lexical cohesion system, we propose an approach that directly integrates the speaker distribution when processing the cohesion. A potential boundary is effective if the joint distribut...

This paper aims to introduce students to a new problem-solving method in reading comprehension through analyzing the feasibility of using the lexical cohesion theory based on Systemic Functional Linguistics. For this purpose, an empirical research was carried out to some Chinese college students. Research shows that the lexical cohesion theory can help improve students’ reading speed and accura...
