Opencola Pro 1.1

"Opencola has selected seven search engines that can be searched with a single query: Google, AltaVista, Yahoo!, AllTheWeb, NorthernLight, Teoma, and Dmoz. Users can add their own news sources or blog sites to include in the search and can also choose to search more than 3,000 news sources provided by Moreover. A folder is automatically created for each search.

Users can also add text-based documents (HTML, text files, Adobe Acrobat PDF, Microsoft Outlook, Microsoft Word, Microsoft PowerPoint, or Microsoft Excel) to a folder to start a search. Opencola will extract the key phrases from the documents and use them to find relevant information or relevant peers. Users then tag results items that they feel to be relevant, and the Semantic Relevance Engine scores other documents (scale of 1 to 100) on how relevant they are to the tagged documents. It then alters the query based on a user’s preferences. New search results are automatically delivered directly to folders at frequency intervals that are defined by the user (daily, weekly, or hourly).

Opencola PRO customers may access other registered users on the global Opencola Knowledge Network. Opencola analyzes similarities between peers on the Knowledge Network and can suggest a user in search results as a “relevant peer.” Opencola allows customers to set permissions for every item in every folder residing within Opencola. Users can browse folders designated as “shared” and download files."

Available for most versions of Windows. There's also an Enterprise version of the product.
