Topsy, a search that provides access to the real time web (news and blogs), tweets, photos, and a search tool to help identify experts using Twitter (Beta, learn more has announced that they just added real time video search to their offerings.
Topsy Video search extends topsy’s socially ranked search technology to videos. The new video search works similarly to other Topsy’s search tools, where the search results will appear ranked based on several factors including Topsy Influence, showing you the most popular and influential videos first.
Retweets are one of the factors to determine influence.
Topsy trending videos provides the top 100, 1000, 5000 videos for each day in a chronological stream. as with other topsy trends (web, tweet, photo) trending videos are the most popular videos shared by influential users within the first 24 hours of their release.
Topsy continues to grow into a very valuable search tool. Two things we hope to see moving forward are an increase in the comprehensiveness of the Topsy Twitter archive. Also, making sure that every current tweet is available.
