Proceedings ArticleDOI
Which Side are You on? Identifying Perspectives at the Document and Sentence Levels
TL;DR: The results show that the proposed models successfully learn how perspectives are reflected in word usage and can identify the perspective of a document with high accuracy.
Journal ArticleDOI
Can High-Level Concepts Fill the Semantic Gap in Video Retrieval? A Case Study With Broadcast News
TL;DR: It is concluded that "concept-based" video retrieval with fewer than 5000 concepts, detected with a minimal accuracy of 10% mean average precision is likely to provide high accuracy results in broadcast news retrieval.
Proceedings ArticleDOI
News video classification using SVM-based multimodal classifiers and combination strategies
TL;DR: The experimental results show that combining multimodal classifiers can significantly improve recall and precision, and the meta-classification strategy gives better precision than the approach of taking the product of the posterior probabilities.
Proceedings ArticleDOI
Extreme video retrieval: joint maximization of human and computer performance
TL;DR: An efficient system for video search that maximizes the use of human bandwidth, while at the same time exploiting the machine's ability to learn in real-time from user selected relevant video clips is presented.
Proceedings ArticleDOI
How many high-level concepts will fill the semantic gap in news video retrieval?
TL;DR: It is concluded that "concept-based" video retrieval with fewer than 5000 concepts, detected with minimal accuracy of 10% mean average precision is likely to provide high accuracy results, comparable to text retrieval on the web, in a typical broadcast news collection.
