1. A computer-readable storage medium having stored and encoded thereon computer-executable instructions for performing on a computing device an enhanced local search of web sites and intranets by mining user access logs, comprising: segmenting the user access log into different browsing sessions; generating ordered pairs of pages from the browsing sessions to find implicit links by using a gliding window to move over explicit paths of the browsing sessions to generate the ordered pairs of pages; determining a frequency of each of the ordered pairs; defining a minimum support threshold; applying the minimum support threshold to the frequency of each of the ordered pairs; filtering the ordered pairs to remove any ordered pairs that are infrequently occurring; constructing an implicit links graph from the implicit links; generating two-item sequential patterns from the ordered pairs; updating the implicit links graph using the two-item sequential patterns; re-ranking search results obtained from a search engine to enhance the local searching to produce updated search results; and displaying the updated search results to a user.
