Abstract
The present invention assists a user in locating an intended address even where an address entered by the user is incorrect. In particular, in accordance with an embodiment of the present invention, an address structure entered by a user containing an existing domain name is considered as a vine of interconnected elements. This vine is then compared to the tree structure of the correctly named domain. A possible match or matches within the domain for the address entered by the user are returned to the user. The possible match or matches may be assigned an accuracy score to assist the user in locating the desired address. The present invention is applicable to any system utilizing addresses that can be considered as a series of elements, such as universal resource locators.
