Quintura is a visual search engine based on the Yahoo! Search engine.
A search returns both a list of search results and a tag cloud. The tag cloud contains the original search terms surrounded by related tags. The closer to the search terms, the larger the keyword suggestions (both in terms of font size and boldness), the more relevant they are deemed. Holding the mouse over a term will display a new set of results in the bottom window and will also show another keyword cloud overlaying the original.
Keywords can be dropped from the semantic display by clicking on the appropriate icon, and any associated keywords are also dropped at the same time. Words can be added to a search by clicking into a blank area in the screen and typing them into the search box that appears; words can be excluded in a similar manner as well with the usual minus sign in front. It's possible to save searches as a favorite or it can be emailed to a friend or colleague.
In February, 2007 Quintura re-launched its user interface, becoming the first search engine to help visually find webpages, images, video, and Amazon products. In November new features enriched the service - a Hot News default cloud, occasional holiday search verticals and search management options - undo/redo actions, Save a cloud as a bookmark or webpage, Share it with friends and Embed it into a website/blog by copypasting its customizable HTML code. In December AltSearchEngines, a leading blog on minor search engines, chose Quintura Alternative Search Engine of the Year for its search widget and "We're not afraid of Google!" marketing campaign.
The innovative graphical user interface (GUI) of Quintura presents search results in two panes - the left pane contains a preset interactive tag cloud and the right pane lists search results. Holding a mouse cursor over a tag in the cloud causes new, related tags to appear surrounding an original tag and search results to change in the scrollable right pane.
Quintura is the first to display graphical images (favorite icons) next to tags (search terms) in the tag cloud. The icon is associated with a URL that corresponds to a search term. Clicking the icon users can visit web pages right from the tag cloud making Quintura easy to use for simple search queries.
Quintura is based on advanced algorithms of artificial intelligence (neural networks). The algorithms simulate the intuitive work of human brain. The Quintura technology helps to develop an idea and build the Semantic Web.
