Discourse Cues for Broadcast News Segmentation
نویسنده
چکیده
This paper describes the design and application of time-enhanced, finite state models of discourse cues to the automated segmentation of broadcast news. We describe our analysis of a broadcast news corpus, the design of a discourse cue based story segmentor that builds upon information extraction techniques, and finally its computational implementation and evaluation in the Broadcast News Navigator (BNN) to support video news browsing, retrieval, and summarization.

Story Segmentation and Detection of Commercials in Broadcast News Video
The Informedia Digital Library Project [Wactlar96] allows full content indexing and retrieval of text, audio and video material. Segmentation is an integral process in the Informedia digital video library. The success of the Informedia project hinges on two critical assumptions: that we can extract sufficiently accurate speech recognition transcripts from the broadcast audio and that we can seg...
متن کاملBroadcast News Parsing using Visual Cues: A Robust Face Detection Approach
Automatic content-based analysis and indexing of broadcast news recordings or digitized news archives is becoming an important tool in the framework of many multimedia interactive services such as news summarization, browsing, retrieval and news-on-demand (NoD) applications. Existing approaches have achieved high performance in such applications but heavily rely on textual cues such as closed c...
متن کاملSegmenting Broadcast News Streams using Lexical Chains
In this paper we propose a course-grained NLP approach to text segmentation based on the analysis of lexical cohesion within text. Most work in this area has focused on the discovery of textual units that discuss subtopic structure within documents. In contrast our segmentation task requires the discovery of topical units of text i.e. distinct news stories from broadcast news programmes. Our sy...
متن کاملSegmentation and Indexation of Broadcast News
This paper describes a topic segmentation and indexation system for broadcast news that is integrated in an alert system for selective dissemination of multimedia information. The goal of this work is to enhance the retrieval and navigation through specific spoken audio segments that have been automatically transcribed, using speech recognition. Our segmentation algorithm is based on simple heu...
متن کاملBroadcast News Story Boundary Detection Using Visual, Audio and Text Features
News video story segmentation is vital for video summarization, story linking, and curation. We present a multimodal segmentation algorithm which fuses video, audio and text cues for story boundary detection. We show that broadcast news closed captioning is a rich and readily available source that improves story boundary detection. Furthermore, we propose an empirical distribution-based feature...
