Regia: a metadata editor for audiovisual documents

Multimedia Tools and Applications, 2007
Although the Metadata Editor is an important part of any digital library, it becomes fundamental in the presence of audiovisual content. This is because the metadata produced by automated support tools (such as speech recognizers and shot detection procedures) is error-prone and often needs correction. In addition, scenes are manually annotated.

Towards a Semantic Multi-modalities Description of Audiovisual Documents

2014 IEEE International Symposium on Multimedia, 2014
The description of an audiovisual document represents a major challenge for multimedia retrieval. Indeed, the lack of descriptive metadata extraction makes these proliferated resources underused in the querying process. To overcome these difficulties, the extraction of the semantic metadata of the content and the different structures of an audiovisual ...

Active reading of audiovisual documents

Proceedings of the 15th ACM international conference on Multimedia, 2007
Active reading is a process in which the reader analyses, and re-uses the object of his reading. The first step of this activity, annotating, is currently well addressed by lots of software. However, organizing annotations or building hypervideos from annotations is currently not well supported.

Towards Fusion of Textual and Visual Modalities for Describing Audiovisual Documents

International Journal of Multimedia Data Engineering and Management, 2015
Audiovisual documents provide a wide range of content description through more descriptors from different media types. Indeed, the extraction of these descriptions has received an increasing attention. But, the lack of semantic description always persists. In fact, this lack affects the retrieval process.

Temporal Relation Analysis in Audiovisual Documents for Complementary Descriptive Information

Lecture Notes in Computer Science, 2006
Relations among temporal intervals can be used to detect semantic events in audio visual documents. The aim of our work is to study all the relations that can be observed between different segmentations of a same document. These segmentations are automatically provided by a set of tools.

Teaching with Audiovisual Documents: Resources in the National Archives

The History Teacher, 1977
THE AUDIOVISUAL Archives Division of the National Archives in Washington, D. C., holds a uniquely comprehensive collection of documents. Unlike the Library of Congress or local historical societies, the National Archives must accept and preserve the records of all government agencies, including both written and audiovisual records.

Automatic Audiovisual Documents Genre Description

Proceedings of the International Conference on Knowledge Discovery and Information Retrieval, 2014
Audiovisual documents are among the most proliferated resources. Faced with these huge quantities produced every day, the lack of significant descriptions without missing the important content arises. The extraction of these descriptions requires an analysis of the audiovisual document’s content.

An audiovisual document for software maintenance

Proceedings. Conference on Software Maintenance, 1988., 1988
Three criteria are used to determine the form and content of a proposed audiovisual document containing videotaped walkthroughs: (1) walkthroughs should be structural behavioral; (2) the maintenance programmer should be able to relate new knowledge to existing knowledge; and (3) the walkthroughs should allow the maintenance programmer to learn by ...

Open Vocabulary ASR for Audiovisual Document Indexation

Proceedings. (ICASSP '05). IEEE International Conference on Acoustics, Speech, and Signal Processing, 2005., 2006
The paper reports on an investigation of an open vocabulary recognizer that allows new words to be introduced in the recognition vocabulary, without the need to retrain or adapt the language model. This method uses special word classes, whose n-gram probabilities are estimated during the training process by discounting a mass of probability from the ...
