Method of and system for determining creation time of a web resource

A server communicatively coupled to a user electronic device and at least one host via a communication network, the at least one host hosting a plurality of pages, the server including a processing module being configured to:

• create a page network comprising the plurality of pages including the target page and a plurality of links,
• each link of the plurality of links having a source page and a destination page, each of the source page and the destination page being one of the plurality of pages, each page of the plurality of pages being one of a source page and a destination page for at least one of the plurality of links,
• each page of the plurality of pages having a corresponding creation time,
• the creation time for each page being one of known and unknown,
• the creation time of the target page being unknown,
• each page of the plurality of pages being associated with a corresponding creation time parameter T indicative of the corresponding creation time of the page,
• assign an initial value to the creation time parameter T for each page of the page network,
• the initial value assigned to the creation time parameter T for any page having a known creation time being the corresponding known creation time;
• vary the initial value of the creation time parameter T of the target page to maximize a page network probability Pnetwork,
• the page network probability Pnetwork being based on a link probability P for each link of the plurality of links, the link probability P for each link being based at least in part on a difference between a creation time parameter T of the source page of the link and a creation time parameter T of the destination page of the link, the difference being the age difference a between the source page and the destination page;
• and
• determine the creation time of the target page to be the value of the creation time parameter T of the target page which maximizes the page network probability Pnetwork.
