URL normalization

Abstract: A system and method are provided for identifying inappropriate content in websites on a network. Unrecognized uniform resource locators (URLs) or other web content are accessed by workstations and are identified as possibly having malicious content. The URLs or web content may be preprocessed within a gateway server module or some other software module to collect additional information related to the URLs. The URLs may be scanned for known attack signatures, and if any are found, they may be tagged as candidate URLs in need of further analysis by a classification module.

Abstract: We demonstrate the usefulness of the uniform resource locator (URL) alone in performing web page classification. This approach is faster than typical web page classification, as the pages do not have to be fetched and analyzed. Our approach segments the URL into meaningful chunks and adds component, sequential and orthographic features to model salient patterns. The resulting features are used in supervised maximum entropy modeling. We analyze our approach's effectiveness on two standardized domains. Our results show that in certain scenarios, URL-based methods approach the performance of current state-of-the-art full-text and link-based methods.

Abstract: A Web browser running on a client machine typically includes an address field in which a Uniform Resource Locator (URL) may be entered. The URL identifies a particular server (or file) located at a target Web site. If a given URL is entered incorrectly at the Web client, a fuzzy URL detection scheme automatically performs a fuzzy search that returns a list of URLs that most closely match what was originally entered into the browser address field. The user can then select the correct URL from the list and launch the browser to the desired site, or to a directory or file within that site. If the fuzzy search does not reveal a match, the browser may contact a server dedicated to performing a broader fuzzy search. In another alternative, the browser contacts a Web server and the fuzzy search is implemented at the Web server in order to return a particular file.

Abstract: The present invention provides methods and systems for accessing a network URL through a pre-assigned simplified network address, correlating to the URL, and for displaying the home page having the URL as its address. These methods and systems provide easier URL and home page access because persons wanting to access the home page need only input the simplified network address, thereby avoiding the need to know and input the URL character string. The simplified network addresses of the present invention include numbers. Methods are provided for selecting numbers for assignment to URLs. The URL and home page access and display methods of the present invention include: assigning a simplified network address such as a number to a URL, storing the URL and number conversion in a network accessible storage system, inputting the assigned number in a network accessible computer, communicating the inputted number to the storage system, converting the number to the URL, retrieving the home page corresponding to the URL and displaying the home page on the computer. Additionally, the invention provides methods for use in message passing operating systems wherein system level messages to specific objects are intercepted, creating an alias message.
