Identifying excessively reciprocal links among web entities
First Claim
1. A computer-implemented method for identifying reciprocal links comprising:
- determining, for a particular host, a value that is based at least in part on both (a) an intersection of (i) a first set of hosts and (ii) a second set of hosts and (b) a union of (i) the first set of hosts and (ii) the second set of hosts; and
presenting a list of ranked search results in which a rank of at least one web page that is hosted by the particular host is based at least in part on the value.

Abstract
A method for identifying reciprocal links is provided. At a particular host, the set of hosts which link to the particular host and the set of hosts to which the particular host links are determined. The intersection and union of the two sets of hosts are also determined, and the sizes of the intersection and union are calculated. The concentration of reciprocal links at the particular host is calculated based on the sizes of the intersection and union. A ratio of the intersection size to the union size is used to determine the concentration of reciprocal links. The particular host'"'"'s rank in a list of ranked search results may be changed as a result of identification of a high concentration of reciprocal links.

10. A computer-implemented method comprising:
for each host in a plurality of hosts, determining, for the each host, a value that is based at least in part on both (a) an intersection of (i) a first set of hosts and (ii) a second set of hosts and (b) a union of (i) a first set of hosts and (ii) the second set of hosts; associating the each host with the value wherein the step of associating comprises storing the value in a computer-readable medium; and presenting a list of ranked search results in which a rank of at least one web page that is hosted by the each host is based at least in part on the value associated with the each host and values associated with other hosts in the plurality of hosts. - View Dependent Claims (11)
