YouTube starts tonight at its test site TestTube the video search for keywords. These so-called "Topics" are automatically generated and displayed on the clips. Please click on a keyword lists videos that are thematically related. "We here develop their own vocabulary for the video search," said YouTube developer Palash Nandy. He gave no details of when the new regular feature will be available to the site on. The keywords could be similar to Google AdWords advertisers in the future be of interest to it.

"People do not know what to look, because they do not know what it is,” said Nandy. That is the difference between a web search and video search. Anyone who uses a search engine, has a certain result in mind, but does not know where to find it. For videos, the requested content, however, are not defined exactly. YouTube can be seen, for example, a search for "funny" videos are not in a position to what the searcher means by "funny".

To videos delivered comments are no help. What one person there as super fun means, find another simply silly.Topics will explore with the YouTube, if and how keywords are used for video search. They function like tags, but are specially programmed algorithm of comments, behavior patterns of users and other parameters calculated by. Over a video of fighter jets, for example, could impact word combinations such as Air Force jets, air show films or Blue Angels aerobatic team may result.
