Systems and associated methods for clustering a plurality of nodes based on connectivity among the plurality of nodes, determining relevant content of the clusters, and applying knowledge regarding the relevant content are described. The nodes can include for example web-based documents such as web pages. The clusters can include for example groups of web pages that are linked together, as via hyperlinks. The relevant content can include one or more topics associated with the web page, as for example determined via text mining. Applying the knowledge regarding the relevant content can include for example using the one or more topics associated with the web pages to augment search results and/or conduct contextual advertising. |
