Multimedia_search
Multimedia search enables information search using queries in multiple data types including text and other multimedia formats. Multimedia search can be implemented through multimodal search interfaces, i.e., interfaces that allow to submit search queries not only as textual requests, but also through other media. We can distinguish two methodologies in multimedia search:
- Metadata search: the search is made on the layers of metadata.
- Query by example: The interaction consists in submitting a piece of information (e.g., a video, an image, or a piece of audio) for the purpose of finding similar multimedia items.
