Definitions

  • This invention relates to retrieving information from one or more Web servers connected on a data network such as the Internet, and more specifically, to personalizing such information regardless from which Website it is retrieved.
  • Some sites e.g., CNN and Quicken
  • Some sites address this problem by allowing a user to create personalized pages that contain only information that is of interest to the user.
  • Other sites send notifications when the underlying data changes and some condition is met.
  • Some problems with these approaches to personalization include: 1) personalization is limited to the information accessible from a single site; 2) personalization features are not offered by all Web sites that might be of interest to a user; and 3) since sites that provide personalization require users to sign up, privacy issues may be involved because the user needs to divulge personal information when signing up thereby potentially enabling the sites to track the interests of the user.
  • a user creates, from his own client computer through his browser operating in conjunction with a personalization applet or application, a personalized Web view comprising a set of Web clippings that contain information content from a plurality of user- selected source Web pages wherein when such personalized Web view is active on the user's client, each Web clipping component of that view is automatically and independently refreshed at a rate that has been specified by the user.
  • any source Web page can be selected by a user to be a Web clipping component of the personalized Web view.
  • the user accesses the source Web page of his interest, extracts those elements within the source page that he wants included within the clipping, defines a layout of such information content within the clipping, if necessary, and the layout of the clipping itself within the totality of the composite Web view.
  • the creation of a personal Web view consisting of multiple Web clippings through the extraction of elements from a source page to form a Web clipping is the subject of the above noted co-pending patent application entitled "Method and Apparatus for Web-Site- Independent Personalization From Multiple Sites Having User-Determined
  • Web information An important characteristic of Web information is that it may change frequently. For example, news sites may be updated hourly, financial sites may update stock prices every 20 minutes, weather updates are provided every three hours, online classified ads change daily, etc.
  • the user in creating each Web clipping component of the composite personal Web view, the user can specify an independent refresh rate for that clipping. If the user, in creating that Web clipping does not specify a refresh rate, then a default refresh rate is set when the Web view is active.
  • the user in creating each clipping the user can specify a notification mechanism for alerting him or whomever or whatever he designates when the occurrence of a specified event condition is detected upon a refresh of that Web clipping.
  • a clipping on the personalized page contains specified current stock prices from a selected Web site
  • the user can incorporate as part of the personalized page a notification mechanism that alerts him by email, by an automatically generated phone call, by page, or by other methods, when, for example, there has been any change at all in the extracted stock information or, employing a finer level of comparison, if one or more of the specified stocks has changed in value by some absolute or percentage basis since either the last refresh instance or since some plurality of past refresh instances.
  • each Web clipping specification is processed by the personalization applet or program by retrieving the source Web page, extracting the information content as defined by the clipping specification, creating a frame (or a layer) according to the layout specifications, inserting code into the frame to ensure that the frame is refreshed at the specified time interval and, if a notification is defined, executing such notification upon the occurrence of the specified event condition, and displaying the Web clippings in the composite Web view in accordance with the defined layout.
  • the source Web page of a clipping may be accessible via direct access through the input of its URL address, some Web pages may not be directly accessible and require multiple browsing steps to retrieve them. If the information of interest that the user wants to include within his personalized Web view is on such a page that is not retrievable via a direct input of a URL a methodology for automatically accessing such a page is employed. Whereas any Web language could be used to automate this process, a user would be required to write a customized program to access each such page. In order to build a system that is targeted to the casual user who is not a programmer, other methodologies are used for automatically creating such access programs as needed.
  • smart bookmarks and site descriptions are used to achieve the necessary functionality that enables direct access to the Web page containing the information that the user wants incorporated within his personal Web view when the Web page cannot be accessed through a direct step.
  • Smart bookmarks are used to transparently record user navigation sequences, which are then stored as an access script that can later be automatically replayed to retrieve the required data.
  • Site descriptions provide a simple and succinct way to represent the structure and contents of a Web site, and can be generated semi-automatically by example. Given a set of such descriptions, the user is able to simply select site descriptions and contents of interest without having to specify how they should be retrieved.

  • a user through his client terminal 101 having a monitor 102, can create and then later replay a personalized Web view that contains Web clippings from one or more Web pages.
  • the user can specify how frequently that Web clipping should be refreshed when the resultant Web view is active in the user's browser or on a server. Further, the user can specify if and how he should be notified upon the occurrence of some specified event condition in that Web clipping that occurs when then information content in that clipping changes upon its being updated.
  • the user specifies exactly what information content that is resident on that Web page that is to be extracted and included and how that extracted information is to displayed on the composite Web view being created.
  • the creation of the Web view is effected through the user's browser
  • PA personalization applet
  • the PA 104 enables the user to customize access scripts that are generated from smart bookmarks or site descriptions (an extension of navigation maps). Smart bookmarks, and how they are created and replayed, are the subject of a co- pending patent application Serial No. 09/387571 entitled “Method for Providing Fast Access to Dynamic Content on the World Wide Web", filed August 31 , 1999, and in a paper entitled “Automating Web Navigation with the WebVCR", by V. Anupam, J. Freire, B. Kumar and D, Lieuwen, Proc.
  • Navigation maps are the subject of co-pending patent application Serial No. 09/263679 entitled “Method and Apparatus for Querying Dynamic Web Content”, co-pending patent application Serial No. 09/263680 entitled “Method and Apparatus for Extracting Navigation Maps From Web Sites", both filed March 5, 1999, and a paper entitled “A Layered Architecture for Querying Dynamic Web Content", by H. Davulcu, J. Freire, M. Kifer, and I. Ramakrishnan, Proc. of SIGMOD, pages 491-502, 1999, which are both incorporated herein by reference.
  • Site descriptions extend navigation maps in two significant ways: they provide more flexibility in the selection as well as format of retrieved information; and they also provide a finer-grained specification of input and output parameters for retrieving information from specific nodes in the site description graph.
  • Site descriptions are the subject of a paper entitled "Personalizing the Web Using Site Descriptions" by V. Anupam, Y. Breitbart, J. Freire, and B. Kumar, Proceedings ofDEXA Workshop 1999, pages 732-738, and is incorporated herein by reference.
  • Each source Web page that contains information that is included in a composite Web view can be accessed either by directly accessing the URL of a Web page on which the desired information resides, or by selecting a node (or a set of nodes) in the site description where the desired information resides (alternatively, handles that represent such information and that encode the access path to the desired information can also be selected), or by a smart bookmark.
  • Selected nodes, handles, or smart bookmarks encode a series of navigation steps that lead to the Web page with the desired information.
  • Pre-established smart bookmarks and site descriptions that enable a user to directly access desired information that would otherwise require multiple navigation steps by the user can be accessed either locally on the client terminal 101 in file 105 or database 106, respectively.
  • a pre-existing smart bookmark can be accessed through the World Wide Web (WWW) 107 from a server 108 through which the desired smart bookmark is stored as a file109.
  • a pre-existing site description can be accessed through the WWW 107 from a server 110 through which such site descriptions/navigation maps are stored in a database 111. If a smart bookmark or a site description is not available to access information which cannot be directly accessed through the input of a URL and would otherwise require a series of navigation steps to retrieve, the user can create either a smart bookmark or a site description on demand as the Web clipping is being created. Creation of such smart bookmarks and site descriptions/navigation maps are described in the aforenoted co-pending patent applications.
  • a Web view Once a Web view has been created by the user, it can be stored locally on the user's machine in a database 112 for later access by the user. In this mode, the creation and display of the Web view through the PA acts as the user's personal tool. All steps involved in the creation and display of the Web view occurs within the user's machine and are stored in that machine.
  • the user is able to maintain complete privacy over his view and the information in that view.
  • a Web view can be created through a personalization server 114 connected to WWW 107 and stored in a database 115. Users from anywhere on the Web may then have access to the Web views stored in the database 115 which are accessed through server 114.
  • the personalization applet 104 written to run on the user's machine 101 in conjunction with that machine's browser 103 can be written in the JAVA language or any other browser-supportable language. If running on server 114, the application performing the necessary functions can be written in any computer language.
  • FIG. 2 the methodology and software components of the personalization applet 200 used to create a Web view are shown in block diagram format.
  • a Web view is a set of Web clippings each of which is derived from a source Web page.
  • the Web clippings that together comprise the Web view can be created by the user one-by-one. Alternatively, one or more previously created Web clipping can be incorporated within a Web view as it is being created.
  • a user by calling upon the personalization applet 200 through his browser, initiates the creation of a new Web view.
  • the Web view manager 201 within the personalization applet 200 functions to assemble various Web clippings together to form the view. It provides the user with the ability to specify how the resulting information content in the Web clipping will be physically arranged in the browser.
  • the Web view manager 201 is also responsible for storing the Web view specification in database 212 when the Web view has been completed.
  • the Web clipping manager 202 is responsible for the creation of the individual Web clippings that constitute the Web view through the selection of access scripts, and the customization and specification of the extraction of requested information content from the Web page that contains that information.
  • the Web clipping manager 202 signals the access script manager 203.
  • the access script manager creates a script to 1) access a single URL if the clipping is reachable through the input of that URL; 2) read and customize an existing smart bookmark from smart bookmark file 213 to access the information to which that smart bookmark leads; or 3) read and customize an existing handle generated from a site description/navigation map from database 214 to access the information to which that navigation map leads.
  • a smart bookmark can be created through a smart bookmark recorder/player 204 and then saved in the smart bookmark file 213.
  • a site description/navigation map can be created by site description recorder/player 205 and then saved in the site descriptions database 214.
  • Access script manager 203 then creates a script to access the desired information from the customized smart bookmark, the customized site description, or the direct URL, which is returned to the Web clipping manager 202 together with the retrieved Web page. That script consists of a sequence of executable steps that are going to retrieve the desired information. For a smart bookmark, those steps are a sequence of navigation steps.
  • a site description is a tree where each node in the tree represents a Web page, and edges between nodes represent actions that are required to go from one page to the next.
  • the tree encoded by a site description can be displayed on a GUI. The user may then select one or more nodes in that tree through the GUI, and given that selection, algorithms as described in the previously noted co-pending patent applications relating to navigation maps, are used to generate a script to access the selected page. Alternatively, handles that are pre-generated for particular nodes in the tree can be selected. If a single URL is specified for the Web clipping, the access script for that clipping consists of a single step to retrieve that Web page at that URL.
  • Handles include the description of the information that is retrieved by the handle (for example, a relation); a set of input attributes that include the mandatory attributes that a user must specify in order for the information to be successfully retrieved, and the optional attributes that can be further specified; output parameters that describe which fragments of the information retrieved should be returned to the user; and the navigation expression that encodes the navigation process to retrieve the desired information.
  • a user may select specific nodes in a site description, in which case the navigation map associated with the site description is scanned, and a handle with the required navigation expression is generated.
  • the navigation expression in a handle can be automatically generated as described in the algorithms in the above noted patent application, Serial No. 09/253679.
  • the user In customizing a handle to access specific information of interest, the user must specify the obligatory attributes, any optional attributes, as well as the output attributes in which he is interest.
  • the navigation expression in the handle can then be executed by either a transaction F-logic interpreter, or it can be translated into another language (e.g., Java or C), compiled and executed. If all attributes are specified, a completely bound navigation expression is created. Rather than creating a completely bound expression, the user can choose to be prompted to enter certain attributes when the Web view is replayed. Thus, each time the Web view is replayed, the user is able to specify such information.
  • a smart bookmark may also be parameterized, in which case the user must specify the required parameters.
  • a completely bound smart bookmark is generated (similar to a navigation expression) which can be replayed by a smart bookmark player, as described in the above-mentioned patent application, Serial No. 09/387571.
  • the smart bookmark need not be bound to a fixed set of attribute values.
  • the user can be prompted to enter a particular attribute value.
  • a smart bookmark is to a Web site which provides current stock ticker information, the stock symbols for the stock(s) of interest will need to be inputted by the user.
  • Such attributes can be specified when creating the Web clipping and saved as part of the clipping so that when the Web view is later replayed, the Web clipping with the user's personal information is automatically retrieved and made part of the view.
  • the user can be prompted for those particular attributes before the information in that particular Web clipping is retrieved and displayed.
  • This feature is useful not only for security reasons (e.g., a user may not want to save a password), but also for creating general clippings and views that can be shared by a group of users.
  • users can download and customize them. For example, if a generic clipping is created for the 401 (k) site, a user may customize it with his own personal information such as his login name and password.
  • Site descriptions provide a detailed model of a Web site that encodes the topology, capabilities, as well as a description of the information that the site exports.
  • site descriptions may export a relational view of the information provided by a Web site.
  • site descriptions allow a much finer customization than smart bookmarks in that sophisticated queries can be posed over the retrieved information.
  • the user is allowed to select output attributes that are a subset of the information that is retrievable, which corresponds to specifying projections in a relational database.
  • Such information content may be a table or part of a table on the page, or any identifiable object on the page.
  • One such methodology is through a GUI that enables the user to select the specific information on the source Web page to be included within his personal Web view by pointing and clicking on the information. This can be done, for example, by parsing the displayed page through a parser 210 to generate the document object model (DOM) of the source Web page, which is displayed in a separate window.
  • DOM document object model
  • the corresponding piece of the Web page can be highlighted in the browser to enable the user to identify his selections. Since DOM elements are uniquely identifiable in a Web page, the selected expression can simply use the DOM address to define which piece should be extracted by extractor 211. Given, however, that some Web pages are dynamic and may change often, additional parameters may be defined in order to make the extraction more robust to changes that might later occur. For example, the user may specify or the parser 210 may identify strings that surround or are within the desired element. The inclusion of additional information, such as identifying strings, advantageously improves the likelihood that the Web clipping, and thus the personal Web view will retrieve the desired information when it is later replayed.
  • parser 210 since many HTML pages are not well-formed, there may be missing tags, tags for different elements may overlap, etc., the parser must correct such page anomalies. Thus parser 210 generates an equivalent well-formed version of the source Web page from which a clipping is to be extracted. Although currently most Web pages are HTML- formatted, Web pages are likely to be formatted in the XML format or another format in the future. For XML pages, in particular, since they can only be displayed if they are valid (and well-formed), such pre-processing of the source Web page is not necessary. It should be noted that present invention could be used with Web pages which are formatted with any type of markup language, whether presently known or created in the future. Other GUIs could also be used that automatically generate extraction expressions.
  • An example could be a point-and-click interface that lets users select portions of Web pages (as he sees them in the Web browser), and provides him with different levels of abstraction that correspond to a breadth-first search in the portion of the document tree that is visible in the browser. For example, if a user is interested in particular cells of a table, he must first select the table and then, zoom into the table to select the desired cells.
  • the inclusion of redundancy within the extraction expression is key to the robustness of the expression to insure that when the Web view is later replayed, the Web clipping will include the information originally intended by the user when the clipping was created, even if the underlying Web pages change between the time the clipping is created and the time it is replayed.
  • a refresh rate which indicates how frequently the information contained within that clipping should be updated or retrieved from the Web when the personal Web view is replayed and active. If no refresh rate is specified, then a default value can be used.
  • the system saves the previous clipping content.
  • the event condition is then tested against the old and new versions of the Web clipping content.
  • Such an event condition can be as simple as "if any change occurs to the content", which can be easily determined by comparing the present and the past instances of the Web clipping, or as complex as "if the stock price for Lucent Technologies goes up more than 30%,” which requires the ability to identify specific pieces of information within the Web clipping.
  • N versions of a Web clipping for some predetermined period of time to support temporal queries such as "if the stock price for Lucent Technologies went up more than 30% in the past week.” If the event condition holds, then action A is executed.
  • This action can take many forms. For example, it can be an email message, a phone call, or a page, directed to the user and/or to whomever the user designates, or a popup window on the user's terminal to alert the user about the change. Further, it can also trigger the refresh of another related Web clipping within the personal Web view, such as if the stock price for Lucent Technologies goes up more than 30%, refresh a Web clipping within the common Web view from a news site such as news.com/finance.
  • the layout of the clipping may need to be specified if it contains more than one element from a source page. Further, the layout of the clipping with respect to entire Web view may be specified such as by specifying the size of the frame that the clipping should occupy, the X,Y coordinates of where the information within the clipping is to be placed and other options such as, for example, whether or not the clipping is scrollable. A default layout can also be specified in which case the system will place the Web clipping in the Web view according to how the system determines them to be best placed. The layout may also be specified by a point-and- click-and-drag interface, where users visually manipulate frames corresponding to Web clippings, to resize them, and place them at a desired position within the Web view window.
  • Web clipping manager 202 having completed the Web clipping, forwards the specification of this completed clipping to the Web view manager 201.
  • All the information that has been inputted by the user that defines the individual Web clippings and the composite Web view is stored as a Web view in a database 212 that is local to the user's machine.
  • the Web view can be stored in a database 216 associated with a trusted third party server 217 on the Web 218, which can be accessed by the user who created the Web view or any other user.
  • FIG. 3 is an example of a Web view as displayed on a browser that includes four Web clippings: Web clipping 301 is derived from the Quicken (www.quicken.com) Web site; Web clipping 302 is derived from Web site from which a user's personal 401 (k) account can be retrieved; Web clipping 303 is derived from a CNET News Web site (news.cnet.com); and Web clipping 304 is derived from a CNN Web site (www.cnn.com). Table 1 shows the internal representation of the Web view in FIG. 3. Table 1
  • the Web clipping 301 from the quicken.com Web site is accessed, as noted in Table 1 , with the quicken_access_script, which in this example accesses the source Web page, as shown in FIG. 4, with a direct URL.
  • ⁇ clippingScript> contains a pointer to a script that has the required actions to retrieve the specific Web page, which in this case can be retrieved with a direct URL. Since the creator of the Web view is only interested in the Default Portfolio that is displayed on that Web page in a table, that table, the second table on the Web page, is extracted for the clipping with the ⁇ extract> function. Further, the refresh rate for this clipping is set at 20 minutes. Thus, when the Web view is active, the script will be executed every 20 minutes.

Abstract

L'invention concerne une vue Web personnelle qui comporte plusieurs extraits du Web. Chaque extrait contient des informations provenant d'une page, toute page accessible sur tout serveur Web, sélectionnée par l'utilisateur. Lors de la création de la page, l'utilisateur charge dans son serveur un applet de personnalisation et extrait chaque page Web intéressante. L'applet génère ensuite un scénario d'accès destiné à accéder automatiquement à une page Web et l'utilisateur définit les attributs de l'extrait du Web tiré de cette page Web. Parmi ces attributs figurent une définition des informations à extraire d'une page Web donnée, et comprises dans l'extrait, une fréquence de rafraîchissement indiquant la fréquence à laquelle ces informations doivent être mises à jour, un schéma de notification indiquant l'action de notification à adopter si un événement spécifié se produit lorsque les informations sont mises à jour, et un agencement de l'extrait du Web. Une définition de la vue Web est alors mémorisée dans un fichier. Lorsque la définition de la vue Web est relancée ultérieurement, la page Web de chaque extrait du Web est extraite, ainsi que les informations sélectionnées. Les extraits du Web sont alors affichés dans un navigateur conformément à un agencement défini. Lorsque la vue Web est active, les informations de chaque extrait du Web pour lequel une fréquence de rafraîchissement est spécifiée ou instaurée comme définition par défaut, sont continuellement mises à jour à cette fréquence par extraction de la page Web associée. Si l'événement spécifié concernant un extrait du Web se produit, l'action de notification associée est alors lancée.
