Global - Find search engines from across the world with Search Engine Colossus Search Engine Land (sengineland) Video search engine A video search engine is a web-based search engine which crawls the web for video content. Some video search engines parse externally hosted content while others allow content to be uploaded and hosted on their own servers. Some engines also allow users to search by video format type and by length of the clip. Video search engines are computer programs designed to find videos stored on digital devices, either through Internet servers or in storage units from the same computer. Utility[edit] The main use of these search engines is the increasing creation of audiovisual content and the need to manage it properly.

[edit] All video formats incorporate their own metadata. [edit]
Glean Comparison Search: An Educational Research and Search Tool SearchEngine Land: Must Read News About Search Marketing & Sear DuckDuckGo Google Correlate Google Correlate is an experimental new tool on Google Labs which lets you use the same methodology and data as Google Flu Trends. What is Google Correlate? Google Correlate is like Google Trends in reverse. With Google Trends, you type in a query and get back a series of its frequency (over time, or in each US state). With Google Correlate, you enter a data series (the target) and get back queries whose frequency follows a similar pattern. Correlated Queries When you upload a data set (a time series, for instance), Google Correlate will compute the Pearson Correlation Coefficient (r) between your time series and the frequency time series for every query in our database. For example, say your data set was a sine wave from 2003-2010, so that 0.0 is the summer solstice and 1.0 is the winter solstice. This could be generated in Excel using the SIN or COS function. To get your data into Google Correlate, you have two main options: We’ll use the copy/paste technique here. 0.9483 alpine touring
The Future of Question and Answer Sites Since the early days of the Internet people have been gathering around common interests and sharing knowledge. The early bulletin board services, Usenet, and message boards provided a great place to get advice form people who were passionate and knowledgeable about any subject imaginable. Today, there are many places online where you can pose a question. These sites often suffer from two general problems: a lack of experts to give strong, accurate answers, and secondly a general lack of audience scale to help ferret out niche knowledge from the masses. Without enough experts sites can wither away or simply be unfocused. While everyone waits for Facebook to unveil their anticipated “location” feature to compete with Foursquare, Gowalla, and Twitter, Mark Zuckerberg’s company has begun previewing a new component to the site: Facebook Questions. Using Facebook Questions users can pose a question to the Facebook community. Just coming out of beta, Quora takes a middle approach.
