“…To this end, a support vector machine (SVM) based summarization model is trained to integrate a set of 28 commonly-used prosodic features (Liu and Hakkani-Tur, 2011) for representing each spoken sentence, since SVM is arguably one of the state-of-the-art supervised methods that can make use of a diversity of indicative features for text or speech summarization (Xie and Liu, 2010;Chen et al, 2013). The sentence ranking scores derived by QMM and SVM are in turn integrated through a simple log-linear combination.…”

“…On the other hand, extractive speech summarization aims at producing a concise summary by selecting salient sentences or paragraphs from the original spoken document according to a predefined target summarization ratio (Carbonell and Goldstein, 1998;Mani and Maybury, 1999;Nenkova and McKeown, 2011;Liu and Hakkani-Tur, 2011). Intuitively, this task could be framed as an ad-hoc IR problem, where the spoken document is treated as an information need and each sentence of the document is regarded as a candidate information unit to be retrieved according to its relevance to the information need.…”

“…Obviously, speech is one of the most important sources of information about multimedia. Users can listen to and digest multimedia associated with spoken documents efficiently by virtue of extractive speech summarization, which selects a set of indicative sentences from an original spoken document according to a target summarization ratio and concatenates them together to form a summary accordingly [4][5][6][7]. The wide array of extractive speech summarization methods that have been developed so far may roughly fall into three main categories [4,7]: 1) methods simply based on the sentence position or structure information, 2) methods based on unsupervised sentence ranking, and 3) methods based on supervised sentence classification.…”

“…Even if the performance of unsupervised summarizers is not always comparable to that of supervised summarizers, their easy-to-implement and flexible property (i.e., they can be readily adapted and carried over to summarization tasks pertaining to different languages, genres or domains) still makes them attractive. Interested readers may also refer to [4][5][6][7] for thorough and entertaining discussions of major methods that have been successfully developed and applied to a wide variety of text and speech summarization tasks.…”
