圖書封面Titlebook: Automated Metadata in Multimedia Information Systems;  Michael G. Christel Book 2009 Springer Nature Switzerland AG 2009
影響因子Improvements in network bandwidth along with dramatic drops in digital storage and processing costs have resulted in the explosive growth of multimedia (combinations of text, image, audio, and video) resources on the Internet and in digital repositories. A suite of computer technologies delivering speech, image, and natural language understanding can automatically derive descriptive metadata for such resources. Difficulties for end users ensue, however, with the tremendous volume and varying quality of automated metadata for multimedia information systems. This lecture surveys automatic metadata creation methods for dealing with multimedia information resources, using broadcast news, documentaries, and oral histories as examples. Strategies for improving the utility of such metadata are discussed, including computationally intensive approaches, leveraging multimodal redundancy, folding in context, and leaving precision-recall tradeoffs under user control. Interfaces building from automatically generated metadata are presented, illustrating the use of video surrogates in multimedia information systems. Traditional information retrieval evaluation is discussed through the annual Nati

Angela Wroblewski,Udo Kelle,Florian Reithy discusses the broad range of metadata possibilities [13]. It can be free-form text or in structured form making use of controlled vocabularies. Metadata can describe the multimedia resource as a whole, or can describe a portion of it, e.g., a particular frame from within a video sequence. Metadata can serve a variety of purposes [13]:

,Evolution of Multimedia Information Systems: 1990–2008,This lecture discusses the role of automatically produced descriptors for multimedia source material, based on more than 14 years of work by the author with the Informedia research group at Carnegie Mellon University (www.informedia.cs.cmu.edu). This opening section defines terms in setting the scope for the lecture.
