Explain the strategy commonly used for searching multimedia archives. List the limitations associated with this strategy.
What will be an ideal response?
Interfaces to structured databases and textual-document libraries are good and getting better, but search interfaces in multimedia-document libraries are a greater challenge. To locate items such as images, videos, sound files, or animations, most systems depend on text searches in descriptive documents or searches on keywords, tags, and metadata. For example, searches in photo libraries can be done by date, photographer, medium, location, or text in captions, but without captioning and human annotation, finding a photo of a particular ribbon-cutting ceremony or horse race is very difficult.
Collaborative tagging of multimedia documents is dramatically changing how users search for photos, videos, maps, and web pages (Section 12.3), but many important collections remain untagged. Even if completely automatic recognition is not possible, however, it is useful to have computers perform some filtering.
Multimedia-document search interfaces have to integrate powerful annotation
and indexing tools, search algorithms to filter the collections, and media-specific browsing techniques for viewing the results. Types of searches might include the following: Image searches, map searches, design or diagram searches, sound searches, animation searches or video searches.
