Contrastive summarization is the problem of jointly generating summaries for two entities in order to highlight their differences. In this paper we present an investigation into contrastive summarization through an implementation and evaluation of a contrastive opinion summarizer in the consumer reviews domain.

Previous eye tracking studies [1] demonstrated that a prominent L+H* accent in English instructions evoked a contrastive relationship between discourse referents, immediately guiding listeners’ eye movements to contrastive candidates in the visual scene. However, the visual layout in the previous study conflated looks to contrastive candidates with those to previously fixated object groups, thu...

We were focusing on the core test. One primary and two contrastive systems were submitted. Primary system was a fusion of all GMM-UBM, SVM-GSV and SVM-GLDS systems described in this paper. The first contrastive system was a fusion of GMM-UBM based systems described in Section 3.1, the next was a fusion of SVM based systems described in Section 3.2. All the submitted scores can be interpreted as...

In this study the local and global prosodic exponents of information structure are examined in the production of six Bulgarian question-answer elicited sentences under different focus conditions (broad focus and non-contrastive and contrastive narrow focus). Local cues are the phonetic properties of the nuclear accented syllables, while global cues reflect broader phonetic patterns in the inter...

Contrastive topic is an information structural category that is usually associated with a specific intonation, which tends to be similar across languages (a rising pitch accent). The aim of the present study is to examine whether this also true of Estonian. Three potential prosodic correlates of contrastive topics are examined: marking with a particular pitch accent type, an emphatic realizatio...

The idea of contrast plays an important role in the analysis of information structure and discourse structure. In the literature on information structure, we encounter the concept of contrastive focus and of contrastive topic, and there is also the opinion that focus in general establishes a contrast. In the literature on discourse structure, it is commonly held that there is a discourse relati...

This study explores prosodic strengthening in the production of fortis plosives in Italian as a function of four structural levels of prominence, reflecting differing focal conditions (in order of increasing prominence: postfocal, broad focus, narrow focus and contrastive narrow focus). The overall analysis indicated that for lingual consonants closure duration was the most important acoustic p...
