Abstract:
1. A method for identifying nodes with similar content, said nodes part of a network of nodes, comprising: determining a structure of the network, said structure defined by incoming links and outgoing links between nodes within said network; grouping said nodes within said network into a first set of modules; calculating a first modularity value for each of the modules within the first set, said modularity value indicating a degree of lexical similarity between said nodes within each module; grouping said nodes within said network into a second set of modules, said second set of modules different from the first set of modules; calculating a second modularity value between each of the modules within the second set, said second modularity value indicating a degree of similar content within each module; comparing said second modularity value to said first modularity value; selecting the set of modules associated with the lower modularity value; calculating a topical relevance value for each of the modules in the selected set; selecting those modules whose topical relevance value exceeds said threshold value; and calculating an authority score for the selected modules in the selected set.
