Criteria-specific authority ranking
View Patent ↗A plurality of linkable nodes may be ranked based on their intrinsic scores. The intrinsic scores may be assigned to each node based on an analysis of the respective node with respect to one or more criteria. Links may be identified between the nodes, and a ranking score for each node may be generated based on the intrinsic scores of nodes linked therewith.
1. A method of ranking a plurality of interlinked nodes, the method comprising the steps of:
(a) analyzing each node, with respect to one or more user-specified criteria, so as to measure one or more properties of the node, each of which is independent of the relation of the node to other nodes;
(b) assigning an intrinsic score to each node based on the analysis;
(c) using a processor, generating a ranking score for each node based at least in part on the intrinsic scores of nodes linked therewith and iteratively updating the ranking score of each node based on the product of one or more numbers representing previous ranking scores and one or more numbers representing the intrinsic scores of documents linked therewith.
2. The method of claim 1 , wherein the first user-specified criterion is the presence of unsafe content at the node.
3. The method of claim 1 , wherein the first user-specified criterion is the presence of inappropriate content at the node.
4. The method of claim 1 , wherein the first user-specified criterion comprises the user's age.
5. The method of claim 1 , wherein the first user-specified criterion comprises a topic.
6. The method of claim 1 , wherein the links are directed.
7. The method of claim 1 , wherein the links are undirected.
8. The method of claim 1 , wherein the nodes represent documents.
9. The method of claim 8 , wherein a link represents a reference in one document to another document.
10. The method of claim 9 , wherein the documents are web sites and the links represent hyperlinks.
11. The method of claim 8 , wherein the intrinsic scores reflect the readability of the documents.
12. The method of claim 1 , wherein iteratively updating the ranking scores comprises multiplying a vector of the ranking scores by a matrix that reflects (i) the intrinsic scores of the documents and (ii) links between the documents.
13. A method of ranking a plurality of interlinked nodes that form a network, the method comprising the steps of:
(a) analyzing each node, with respect to one or more user-specified criteria, so as to measure one or more properties of the node, each of which is independent of its relation to other nodes, and assigning an intrinsic score to the node based on the analysis; and
(b) using a processor, iteratively computing ranking scores for the nodes by generating a ranking score for the each node based at least in part on the intrinsic scores of nodes linked therewith and iteratively updating the ranking score of each node based on the product of one or more numbers representing previous ranking scores and one or more numbers representing the intrinsic scores of a list of nodes that includes one or more documents linked therewith.
14. The method of claim 13 , wherein the list of nodes further comprises the immediately preceding node.
15. A system for ranking a plurality of interlinked nodes, comprising:
a processor; and
in communication with the processor, computer memory storing instructions, executable by the processor, for
(i) analyzing each node, with respect to one or more user-specified criteria, so as to measure one or more properties of the node, each of which is independent of its relation to other nodes;
(ii) assigning an intrinsic score to each node based on the analysis;
(iii) generating a ranking score for each node based at least in part on the intrinsic scores of nodes linked therewith and iteratively updating the ranking score of each node based on the product of one or more numbers representing previous ranking scores and one or more numbers representing the intrinsic scores of documents linked therewith.
