There is rising in the race to develop multimedia search engines capable of searching, indexing and cataloging the growing amount of music, images and video available on the Web.
The challenges are lack of resources devoted to tagging and marking up content for use as metadata, the lack of adequate metadata databases and the difficulties associated with indexing dynamic content. These are cited as hurdles that need to be overcome. Wider use of metadata should go a long way, but leading edge multimedia search technology developers are working on a range of other means and methods to improve users’ ability to seek out, find and make use of content.
Higher Level Patterns
mVisible, a distributor of independent digital music and multimedia content via the Web and mobile phone networks, uses fairly typical means of searching for and categorizing content..By extracting some degree of metadata from the content files that are ingested into the system ,such as artist, song, album, etc., and we store that in our database. While not directly involved in developing multimedia search technology, distributors such as mVisible nonetheless have a vested interest in its development and hope to take advantage of advances as they emerge.
Categorizing Multimedia Content
Six of the most commonly used means digital content distributors and search engine providers are using to categorize, index,and enable multimedia searches: by media type; by metadata (such as title, author, producer, lead artist and publisher); by genre; by recommendations specified by human authorities, computer programs or a combination of both; by aspects of data in the file (colors, rhythmic intensity) specified by human authorities, computer programs or a combination of both; and by user or authority ratings.
By Authority of the Peers
The emergence of “wisdom of the crowd,” or peer authority, as equally or more important than traditional authorities, such as eBay and Amazon has been one of the key milestones in the development of multimedia, Hoffert told TechNewsWorld.
Multimedia and Social Networks
Social networking sites have been big drivers of online multimedia content. They’ve grown quickly and now command huge valuations from large, well-established and acquisition-minded media networks and search engine providers keen to capitalize on the growing demand for and use of online multimedia.With more than 18 million unique users each month, Imeem is one of the fastest growing social media networks on the Web.The ability to search for, index and respond to users’ requests for various media and then enable users to use the material when connecting with other people with similar tastes is key to attracting members and differentiating Imeem from competitors.
Performance and Scale
Performance and scalability are two of the main challenges facing Imeem and other social networking sites, according to Jang. Giving users the ability to create music and video playlists gives rise to tracking relationships between different kinds of media, and that contributes further to a sophisticated form of social search.
