receive a list of categorization intervals, the list of categorization intervals including a category re-assignment interval for each network resource,

check the passage of time against each category re-assignment interval, and

upon the passage of time of the category re-assignment interval for each network resource, initiate a re-categorization by utilizing the subcategory assessment engine, the content evaluator engine, and the category comparator engine.

9. A machine-implemented method for categorizing a plurality of network resources, the method comprising:

assigning, by a network resource category assignment engine, a network resource category for one of the plurality of network resources;

assigning, upon initial operation of the network resource category assignment engine, a minimum interval for a network resource category interval for the network resource category;

determining if the network resource category assignment engine assigned a malicious category to the network resource, and if a malicious category is assigned, assigning the minimum interval for the network resource category interval;

calculating a new network resource category interval based on a computed probability of change to an undesirable category; and

assigning the new network resource category interval to the network resource category interval for a subsequent re-assignment of the network resource category.

10. The machine-implemented method for categorizing a plurality of network resources of claim 9 , further comprising:

if no malicious category is assigned to the network resource, determining a content suitability of the network resource; and

if the content suitability of the network resource is determined to be unsuitable, assigning a second minimum interval for the network resource category interval.

11. The machine-implemented method for categorizing a plurality of network resources of claim 10 , wherein the minimum interval and the second minimum interval are the same.

12. The machine-implemented method for categorizing a plurality of network resources of claim 10 , wherein the minimum interval and the second minimum interval are different.

13. The machine-implemented method for categorizing a plurality of network resources of claim 10 , wherein the undesirable category is based on at least one of content suitability or maliciousness.

14. The machine-implemented method for categorizing a plurality of network resources of claim 9 , wherein if the subsequent re-assignment of the network resource category does not change the category, the new network resource category interval is greater than a previous network resource category interval.

15. The machine-implemented method for categorizing a plurality of network resources of claim 9 , wherein if the subsequent re-assignment of the network resource category changes the category, the new network resource category interval is less than a previous network resource category interval.

16. The machine-implemented method for categorizing a plurality of network resources of claim 9 , wherein the computed probability of change to an undesirable category is based on a ratio of durations during which various categories have been assigned to the network resource.
