Abstract: Search systems and methods for connecting users with relevant information about products or services in which they are interested. Relevant information provided to the users includes links to web pages where the product or service is available and links to discussion groups or other social networking communities where the product or service is being discussed and reporting on the frequency of specific brand and product discussions along with sentiment attributes. Embodiments of the present invention advantageously provide an efficient way to provide or connect consumers with relevant information and web-based conversations about products or services in which they are interested, without the consumer having to actively search multiple disparate websites in the hopes of finding relevant information and conversations. Once connected, users are able to dig deeper for additional information, such as by reviewing and/or joining a conversation or accessing additional sites presented by the system.
