CROSS-REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application claims priority to and is a continuation of U.S. application Ser. No. 13/935,514, filed on Jul. 4, 2013, entitled “INTERACTIVE SITEMAP WITH USER FOOTPRINTS”, which is incorporated herein. 
     
    
     FIELD 
       [0002]    The disclosed subject matter broadly relates to the field of sitemaps, and more particularly relates to the field of interactive sitemaps. 
       BACKGROUND 
       [0003]    A sitemap, as defined by Wikipedia is: “A site map (or sitemap) is a list of pages of a web site accessible to crawlers or users. It can be either a document in any form used as a planning tool for Web design, or a Web page that lists the pages on a Web site, typically organized in hierarchical fashion.” A sitemap provides guidance for visitors to a website who want to know about the website structure and the services provided on that website. In some cases, the sitemap is also referred to as a site index. This is the case with the United States Patent &amp; Trademark Office (USPTO) website. The USPTO site index link is displayed on the very bottom of the website. This is also a very common location for the sitemap or site index link; it is usually delegated to the bottom of a page. 
         [0004]    Referring now to  FIG. 1 , there is shown a print screen of a sitemap  100  for the website www.weather.com (The Weather Channel), according to the known art. A look at this sitemap  100  provides quite a bit of information about what is available on the website, much more so than the information revealed in the menu bar  120 . 
         [0005]    Clearly, a sitemap is a good reference for a user who wants to know what a website can offer. When one considers that sitemaps are so commonly found in websites and also considering how much information they can provide, they are relatively unappealing and even meaningless to users. 
         [0006]    There is a need for a system and method that provides a more meaningful and richer user experience in navigating a sitemap. 
       SUMMARY 
       [0007]    Briefly, according to an embodiment of the present disclosure, a method for generating an interactive sitemap includes steps or acts of: receiving an identifier of a user visiting the website; storing identifiers of the website pages visited by the user; associating the website page identifiers with the user identifier; capturing a snapshot of each website page visited by the user; determining website pages recommended for the user, but not yet visited by the user; capturing a snapshot of at least one recommended website page; and generating the interactive sitemap that includes a sitemap tree structure of the website with selectable nodes representing the website pages visited by the user and the website pages recommended for the user. When the user rolls over one of the selectable nodes, presenting the snapshot within the in-page window. 
         [0008]    According to another embodiment of the present disclosure, an information processing system for generating an interactive sitemap of a website includes, inter alia, the following components: a processor device; and a memory device operably coupled with the processor device. The memory device holds the computer-executable instructions for performing the method steps above. 
         [0009]    In yet another embodiment of the present disclosure, a computer program product includes a non-transitory computer-readable storage medium with computer-executable instructions stored therein. The computer-executable instructions, when executed, cause a computer device to perform the method steps above.

       DETAILED DESCRIPTION 
       [0027]    Before describing in detail embodiments that are in accordance with the disclosed subject matter, it should be observed that the embodiments reside primarily in combinations of method steps and system components related to systems and methods for placing computation inside a communication network. Accordingly, the system components and method steps have been represented where appropriate by conventional symbols in the drawings, showing only those specific details that are pertinent to understanding the embodiments of the disclosed subject matter so as not to obscure the disclosure with details that will be readily apparent to those of ordinary skill in the art having the benefit of the description herein. Thus, it will be appreciated that for simplicity and clarity of illustration, common and well-understood elements that are useful or necessary in a commercially feasible embodiment may not be depicted in order to facilitate a less obstructed view of these various embodiments. 
         [0028]    We discuss an interactive sitemap allowing a user to identify and easily traverse and re-visit previously viewed web pages, whether the web pages were visited in a current session or in previous sessions, thus allowing the user to navigate to different properties of a website in a more elegant user experience. The present disclosure will now be described with respect to  FIGS. 2-13  which are block diagrams, exemplary screenshots, and flowchart illustrations of embodiments of the disclosed subject matter. It will be understood that each block of the flowchart illustrations and/or block diagrams, and combinations of blocks in the flowchart illustrations and/or block diagrams, can be implemented by computer program instructions. 
         [0029]    Referring now to  FIG. 2 , there is illustrated a high-level flow chart illustrating a method for constructing an interactive sitemap, according to an embodiment of the present disclosure. The method begins at step  205  wherein the system generates a user interface (UI) button or tab on a website. The user indicates a preference for the interactive sitemap by selecting the UI button. Selecting the UI button, in turn, triggers the system to present the interactive sitemap, rather than the default sitemap that is known in the art. 
         [0030]    In step  210  the system for constructing an interactive sitemap takes snapshot previews for each webpage visited by the user, and for any default and/or recommended pages. The snapshots are taken periodically, at time of visit, at time of web page refresh, or at pre-determined intervals. The snapshot function of the interactive sitemap generation is a cache functionality, especially beneficial for the default nodes (web pages) and recommended nodes (web pages). By taking the periodic snapshots, the screenshots are already generated and ready to display when the user mouses over one of these nodes. 
         [0031]    We define two categories of web pages: Editorial Pages and User Generated Content (UGC) Pages. If the node represents an Editorial Page, a cache system runs in the background. Referring now to  FIG. 14 , we provide an example of a snapshot using the cached web page http://news.yahoo.com/science/ of Yahoo! News  1400  as a default node for the “Science” branch. In one embodiment of the present disclosure, the current, or trending, cover story (stories)  1415  is (are) used as the snapshot for the node. Because the cover story will dynamically change due to the posting of new articles, in this scenario the snapshot can be taken by the cache system whenever a new article is posted. 
         [0032]    Referring now to  FIG. 15  we show an exemplary snapshot  1500  for a UGC Page. Here we display a “tumblr.” web page “Pets” at http://www.tumblr.com/tagged/pets. Because the content of a UGC page such as this one changes due to frequent posts tagged within the ‘Pets’ category, we introduce a mechanism to capture the web page image as a snapshot at predetermined time intervals (for example, every hour) to ensure that the node snapshot preview is up-to-date, while not wasting computing resource time comparing the current web page to each web page updated with a new post. The snapshot will likely be a screenshot showing only a portion of the page. 
         [0033]    In step  220  the identifying information for the web page such as the URLs (uniform resource locators) are stored and associated with the user. The association is accomplished as follows: for login users, the page URLs are saved to a database; for non-login users, the page URLs are saved to browser cookies which are already associated with the user; or in the alternative, the URLs are stored in a data store in a table or index that associates a URL with a user. In this manner any user, even one who has not registered, can interact with the sitemap. 
         [0034]    In one embodiment of the present disclosure, in step  230  we construct a sitemap tree personalized for the user according to the main functions and/or properties of the website, with selectable nodes of the sitemap tree representing the different viewable web pages from the website. For a user&#39;s first visit to the website, we provide default selectable nodes (pages) on the sitemap tree for the user to select. Using a Yahoo! News page as an example (http://news.yahoo.com/) the default nodes represent the landing pages of the categories on the top menu bar—‘World’, ‘Politics’, ‘Tech’ . . . and so on. The user can traverse between each category in the interactive sitemap. 
         [0035]    Assume the user has visited several pages, with his/her focus on viewing articles in the ‘Health’ category. The interactive sitemap will recognize the user&#39;s interests, which in this case is ‘Health,’ and easily present the Health nodes on the tree as a way to return to or initiate a visit to the pages of interest. Once the system has “learned” that the user has a preference for the pages in the ‘Health’ category (branch), that branch will be populated with selectable recommended nodes that the user can preview (with a snapshot). 
         [0036]    The algorithm to build the sitemap tree will likely generate new nodes in a downward direction such that the new nodes will appear on the tips of each “branch” of the tree and on the bottom of the tree. Older nodes will be dropped (eliminated) to keep the sitemap tree clutter-free. Limiting the number of nodes saves the sitemap space for more currently relevant nodes while providing an up-to-date personalized experience. 
         [0037]    In step  240  the sitemap tree is populated with branches representing the different page links associated with the nodes. For a first time visit, there is no history available for the user. In this scenario, we generate the branches, using one or two recommended links. The recommended links that are selected by the system depend on the type of website and which pages are going to be promoted. The types of website can be roughly divided into two types: content sites and e-commerce sites. For a content site such as Yahoo! News, for example, the recommended links will likely be pages from “Top Stories” and/or “Breaking News.” For an e-commerce website, the recommended links will likely be the web pages for Current Bestsellers and/or Editor&#39;s Picks. 
         [0038]    For any subsequent visit to the interactive sitemap, it is likely that some system-generated branches will be replaced by the page links selected by the user. In order to distinguish the nodes from the “recommended” links versus the nodes from the user-selected page links, we display the recommended nodes differently. They can be displayed in a different color or font, de-emphasized (greyed out), highlighted, underlined, or with any other distinguishing feature, as compared to a visited node. Lastly, in step  250  we store the sitemap tree with all appended nodes so that it is available for the user&#39;s next visit to that website, and the user&#39;s selection of the interactive sitemap by selecting the UI button (as shown in  FIG. 4 ). 
         [0039]    Referring now to  FIG. 3 , there is shown a high-level flowchart of the user interaction with the interactive sitemap, from the system&#39;s point of view, according to an embodiment of the present disclosure. First, in step  310  the interactive sitemap system receives the user&#39;s selection of the interactive sitemap from a website. The user can elect to use the interactive sitemap, rather than just the default sitemap, by clicking on a button or following a link as discussed above. In various embodiments of the present disclosure, we elect to place the UI button for the interactive sitemap in a prominent location, such as at a top of a website, rather than the very bottom area relegated to current sitemaps. 
         [0040]    In response to the user&#39;s selection indicating a preference for the interactive sitemap, the interactive sitemap system presents an in-page, or “pop-up” window showing the sitemap tree with nodes representing the pages visited by this user in step  320 . The in-page window is generated with known technology that is beyond the scope of this disclosure. As previously stated, the sitemap tree is also shown with default nodes. In decision step  330 , if the user mouses over (or rolls over) one of the nodes representing a page URL, this indicates to the system that the user wishes to glance at that page. Accordingly, the system displays a snapshot preview of the page associated with the moused-over node in step  340 , in response to the mouse-over. 
         [0041]    If the user has clicked on a node in decision step  350 , the system re-directs the user to the URL of the page associated with the clicked node in step  360 . It should be noted that the selection of mousing-over and clicking are independent of each other, meaning that the user can mouse over and then click, or simply mouse-over, or simply click without first mousing-over. Once re-directed to the webpage, that webpage is set to the current node in the sitemap tree in step  370 . The sitemap tree will show the node associated with the current page in a distinct manner such that the user can easily identify the current node. 
         [0042]    Referring now to  FIG. 4 , we show a sitemap tree  400  according to an embodiment of the present disclosure. This sitemap tree  400  is what the user sees after clicking the sitemap link  475  on a website page. The tree  400  appears on an in-page window within the website. Clicking the sitemap link or UI button  475  triggers the opening of the in-page window shown in  FIG. 4 . The window displays the sitemap tree  400 . Along the horizontal axis of the window the tree  400  displays the properties (main menu)  410  of the website. As shown in  FIG. 4  the properties can be displayed with images  415  along with their names. These images  415  are themselves snapshots of the main page of each property. Along the vertical axis the user footprint/history  420  is represented in a hierarchical tree format. The user footprint/history  420  shows the pages visited by the user represented as nodes  450  on a tree. The node  480  representing the current page is emphasized. One with knowledge in the art will recognize that the horizontal/vertical order of the placement can be changed. 
         [0043]    If the user hasn&#39;t yet visited any page of a certain property, the sitemap tree can be constructed with default/recommended nodes  455  such that the tree does not appear empty when the user first visits. The default/recommended nodes  455  will appear in a distinctive manner on the sitemap tree  400  such that the user can easily note the difference between visited nodes  450  and default/recommended nodes  455 . 
         [0044]    Referring now to  FIG. 5 , there is shown a sitemap tree  400  with a page snapshot  530  showing the page associated with the node moused over by the user, according to an embodiment of the present disclosure. When the user mouses over any node ( 450 ,  455 , or  480 ), we display the page snapshot preview  530  for that node. Additionally, we can also display other relevant information such as the time/date that the user visited the page. Without the time/date display, the user can always tell at a glance which nodes are the most recently visited because they appear on the tips (ends) of each branch. This useful feature entails some back-end work that is transparent to the user. The system may have to re-organize the nodes on the sitemap tree  400  for repeated visits. For example, assume the user visits Sports Page A, then Sports Page B, then Finance Page A. The current node is Finance Page A. Then the user returns and visits Sports Page A. Sports Page A becomes the current node and it is also moved to the “tip” of the sports branch, replacing Sports Page B on the tip. 
         [0045]    Referring now to  FIG. 6 , we show the page redirect after the user clicks on a node  450 . Note that once the user is re-directed to a page, the node associated with that page then becomes the current node  480  and is emphasized in some manner, such as colored-in, highlighted, blinking, or the like. 
         [0046]    Social Network Feature. 
         [0047]    Referring now to  FIG. 12 , we show an exemplary illustration of the social network feature, according to an embodiment of the present disclosure. When this feature is enabled, the node snapshot  530  will include, in close proximity or within the display, the user&#39;s social connections who have been visiting that same page. The social connections  1250  can be shown with their respective social site photo and/or their user name. 
         [0048]    Recommended Pages Feature. 
         [0049]    Referring now to the illustration of  FIG. 13 , we support a Recommended Pages Feature in order to make the interactive sitemap  400  even more meaningful. With this feature enabled, the user will see some smaller nodes  1350  placed near the sitemap nodes  450 . These smaller nodes  1350  represent pages that are recommended for the user based on the user&#39;s tree traversals. 
         [0050]    Monetization Feature. 
         [0051]    Referring now to  FIG. 7  we show a method of monetizing the interactive sitemap. Here we show an advertisement  710  placed within the sitemap  400 . The selection of which advertisement  710  to display can be triggered by the user mousing over a node inside the sitemap tree  400 . The advertisement  710  may be selling a product tied to content of that page or a product that is geared to user profiles of users who select that page. There are many different ways that advertisements are selected that are beyond the scope of this document. Whichever advertisement  710  is selected can be displayed with the snapshot  530  as a way of monetizing. 
         [0052]    Referring now to  FIG. 8  there is shown an interactive sitemap sequence diagram  800 , according to an embodiment of the disclosed subject matter. The sequence diagram  800  shows the sequence of steps performed in order to first generate an interactive sitemap for a user and also the process for interacting with a user on a generated interactive sitemap. Along the horizontal axis of this diagram  800 , along the top, we see the different components (physical and/or logical) that perform the sequence of steps within the interactive sitemap system. First we see the user&#39;s browser  802  that visits a website. The website has various Properties  804 , or main functions, that sub-divide the website. For example, Yahoo! has the properties Mail, News, Sports, Finance, and others. Each time a user initially visits a page in one of these properties, the system generates a new column in the sitemap tree  400 . For an initial visit, the tree  400  is constructed with a default set of Properties  804 . 
         [0053]    Next we see the Footprint Service  806  which records the UUID, the URL of the webpage visited, and the timestamp. A UUID is a “universally unique identifier” that identifies the visitor to the website and the visitor&#39;s travels within the website. This information is stored in either a data store or in the user&#39;s browser cookies. Then the Screenshot Service  808  takes a screenshot or snapshot  530  of the pages the user visits. The information acquired by the Footprint Service  806  is saved as a user footprint in the Database  810 . What has just been described with respect to  FIG. 8  is the process performed to generate an interactive sitemap  400 . These steps are performed for each recurring visit. 
         [0054]    Now moving to the bottom portion of the diagram  800 , we begin with the Sitemap Service  812  which is activated when the user selects the service by clicking on the UI button  475 , or by some other manner.  FIG. 9  shows another example of a UI button  475  used to activate the interactive sitemap. The Sitemap Service  812  collects the UUID, cookies, URLs, and other information that is stored in the Database  810  for this user and calls a Sitemap Generator  818  to construct a Sitemap Tree  400  that is cacheable. The Sitemap Tree  400  is presented to the user as an interactive sitemap in an in-page window. If the user mouses over a node  450  in the Sitemap Tree  400 , an API (application program interface) requests the appropriate screenshot from the Database  810  and then responds to the user with a snapshot image  530  of the page associated with the moused-over node. Clicking on the node  450  will re-direct the user to the node&#39;s page. 
         [0055]    Referring now to  FIG. 10  there is shown a high-level block diagram representing the components in the interactive sitemap system. We begin with the user&#39;s browser  802  which accesses a Website  1005  through a network such as the Internet  1090 . The front-end processing  1010  of the Website  1005  contains the website Properties  804  as well as the UI button  475  for activating the interactive sitemap  400 . The back-end processing  1020  of the Website  1005  contains the Footprint Service  806 , the Screenshot Service  808 , and the Database  810 . The Sitemap Service  812  is activated through the UI  475  and interacts with the back-end processing  1020  to generate a Sitemap Tree  400  through the Interactive Sitemap Generator  818 . 
         [0056]    Those skilled in the art will appreciate that the functionality implemented within the blocks illustrated in the diagram may be implemented as separate components or the functionality of several or all of the blocks may be implemented within a single component. For example, the functionality for the Screenshot Service  808  may be included in the same component as the Footprint Service  806 . Or the functionality of the Sitemap Generator  818  may be implemented as a separate component from the Sitemap Service  812 . Processing is preferably performed using Java-based technologies, although other similar technologies now known or subsequently developed may be used for the processing. 
         [0057]      FIG. 11  Hardware Embodiment. 
         [0058]    Referring now in specific detail to the drawings, and particularly  FIG. 11 , there is provided a simplified pictorial illustration of the hardware components of an information processing system for generating an interactive sitemap in which the disclosed subject matter may be implemented. For purposes of the disclosed subject matter, the illustrated computer system is the Sitemap Generator  818 . Computer system  818  may represent any type of computer, information processing system or other programmable electronic device, including a client computer, a server computer, a portable computer, an embedded controller, a personal digital assistant, and so on. The computer system  818  may be a stand-alone device or networked into a larger system. Computer system  818 , illustrated for exemplary purposes as a networked computing device, is in communication with other networked computing devices (not shown) via a network such as the Internet  1090 . 
         [0059]    In general, the routines which are executed when implementing these embodiments, whether implemented as part of an operating system or a specific application, component, program, object, module or sequence of instructions, will be referred to herein as computer programs, or simply programs. The computer programs typically comprise one or more instructions that are resident at various times in various memory and storage devices in an information processing or handling system such as a computer, and that, when read and executed by one or more processors, cause that system to perform the steps necessary to execute steps or elements embodying the various aspects of the disclosed subject matter. 
         [0060]    Throughout the description herein, an embodiment of the disclosed subject matter is illustrated with aspects of the disclosed subject matter embodied solely on computer system  818 . As will be appreciated by those of ordinary skill in the art, aspects of the disclosed subject matter may be distributed amongst one or more networked computing devices which interact with computer system  818  via one or more data networks. However, for ease of understanding, aspects of the disclosed subject matter have been embodied in a single computing device—computer system  818 . 
         [0061]    Computer system  818  includes processing device  1102  which communicates with an input/output subsystem  1106 , memory  1104 , and storage  1110 . The processor device  1102  is operably coupled with a communication infrastructure  1109  (e.g., a communications bus, cross-over bar, or network). The processor device  1102  may be a general or special purpose microprocessor operating under control of computer program instructions executed from memory  1104  on program data. The processor  1102  may include a number of special purpose sub-processors such as a comparator engine, each sub-processor for executing particular portions of the computer program instructions. Each sub-processor may be a separate circuit able to operate substantially in parallel with the other sub-processors. 
         [0062]    Some or all of the sub-processors may be implemented as computer program processes (software) tangibly stored in a memory that perform their respective functions when executed. These may share an instruction processor, such as a general purpose integrated circuit microprocessor, or each sub-processor may have its own processor for executing instructions. Alternatively, some or all of the sub-processors may be implemented in an ASIC. RAM may be embodied in one or more memory chips. 
         [0063]    The memory  1104  may be partitioned or otherwise mapped to reflect the boundaries of the various memory subcomponents. Memory  1104  may include both volatile and persistent memory for the storage of: operational instructions for execution by CPU  1102 , data registers, application storage and the like. Memory  1104  preferably includes a combination of random access memory (RAM), read only memory (ROM) and persistent memory such as that provided by a hard disk drive. The computer instructions/applications that are stored in memory  1104  are executed by processor  1102 . The computer instructions/applications and program data can also be stored in a hard disk drive for execution by processor device  1102 . 
         [0064]    The I/O subsystem  1106  may include various end user interfaces such as a display, a keyboards, and a mouse. The I/O subsystem  1106  may further include a connection to a network  1090  such as a local-area network (LAN) or wide-area network (WAN) such as the Internet. 
         [0065]    The computer system  818  may also include a removable storage drive  1116 , representing a floppy disk drive, a magnetic tape drive, an optical disk drive, etc. The removable storage drive  1116  reads from and/or writes to a removable storage unit  1120  in a manner well known to those having ordinary skill in the art. Removable storage unit  1120 , represents a floppy disk, a compact disc, magnetic tape, optical disk, CD-ROM, DVD-ROM, etc. which is read by and written to by removable storage drive  1110 . As will be appreciated, the removable storage unit  1120  includes a non-transitory computer readable medium having stored therein computer software and/or data.
