User navigation in a target portal

A computer system for user navigation in a target portal with at least two portal pages, said computer system comprising:

• a memory;
• and
• a processor in communication with the memory, wherein the computer system is configured to perform a method, said method comprising:
• creating at least one query including at least one of uniform resource locators of selected portal pages or content of selected portal pages as search terms in a first search level;
• repeating until a certain abort criterion is reached:
• receiving and analyzing search results of said at least one query including external websites containing search terms as part of their content;
• selecting a set of uniform resource locators from said received search results;
• creating a node in a graph-like-model for each uniform resource locator of said selected set of uniform resource locators, based on the node not already being contained in said graph-like-model and associating said node with said uniform resource locator;
• creating and issuing a further search query including selected uniform resource locators of external websites in an additional search level;
• based on reaching said certain abort criterion performing:
• computing said graph-like-model containing nodes and edges representing direct or indirect references between said external websites and portal pages of said target portal based on said created nodes;
• defining a threshold value for a maximum distance for pairs of portal pages in said graph-like-model;
• calculating distances in said graph-like-model for said pairs of portal pages of said target portal;
• comparing said calculated distances for said pairs of portal pages with said defined threshold value;
• creating an additional navigation path for pairs of portal pages whose distance is smaller than said threshold value;
• and
• displaying said additional navigation path in said target portal.

A computer program product for user navigation in a target portal with at least two portal pages, said computer program product comprising:

• a non-transitory computer readable storage medium readable by a processing circuit and storing instructions for execution by the processing circuit for performing a method comprising:
• creating at least one query including at least one of uniform resource locators of selected portal pages or content of selected portal pages as search terms in a first search level;
• repeating until a certain abort criterion is reached:
• receiving and analyzing search results of said at least one query including external websites containing search terms as part of their content;
• selecting a set of uniform resource locators from said received search results;
• creating a node in a graph-like-model for each uniform resource locator of said selected set of uniform resource locators, based on the node not already being contained in said graph-like-model and associating said node with said uniform resource locator;
• creating and issuing a further search query including selected uniform resource locators of external web sites in an additional search level;
• based on reaching said certain abort criterion performing:
• computing said graph-like-model containing nodes and edges representing direct or indirect references between said external websites and portal pages of said target portal based on said created nodes;
• defining a threshold value for a maximum distance for pairs of portal pages in said graph-like-model;
• calculating distances in said graph-like-model for said pairs of portal pages of said target portal;
• comparing said calculated distances for said pairs of portal pages with said defined threshold value;
• creating an additional navigation path for pairs of portal pages whose distance is smaller than said threshold value;
• and
• displaying said additional navigation path in said target portal.
