Description:
RELATED APPLICATIONS  
       [0001]    This application is based on U.S. Provisional Patent Application No. 60/229,779; filed Sep. 1, 2000 and entitled “Method and System for Displaying Content Over the Internet.”The contents of which are incorporated herein. 
     
    
     
       BACKGROUND OF THE INVENTION  
         [0002]    1. Field of Invention  
           [0003]    This invention relates generally to a system and method for selecting content for displaying over the Internet based upon some user input. Particularly, this invention relates to a system and method of selecting content from a content directory for display in a web-page where the content is based upon some arbitrary user input.  
           [0004]    2. Background of the Invention  
           [0005]    In recent years, web-pages, and other Internet components have changed to incorporate the popularity of customizable, interactive, and dynamic structure. Most existing web-pages contain pre-specified content, where a user simply downloads the source code of the desired page for viewing in an Internet browser. Some web-pages may have limited dynamic components and may offer limited customizability. For example, existing web pages may allow a user to make certain custom settings to a web-page. However, the user is usually prompted for specific information, and has a limited number of choices. A need still exists for a system and method capable of generating and displaying content in a web-page, based upon some arbitrary input by a user.  
           [0006]    3. Summary of the Invention  
           [0007]    The invention disclosed herein is a novel approach which addresses many of these limitations. A general feature of the present invention is to provide a system and method for displaying content over the Internet, based upon some arbitrary user input. The content may include, but is not limited to web content such as pictures and/or links and/or functional programs and/or tables and/or charts and/or functions etc.  
           [0008]    The present invention provides a method for displaying information from the Internet. In one embodiment, the invention generates a plurality of content modules, each content module comprising a subset of the content of at least one web site. The content modules are then stored in a content module data directory. When a query is received from a user, the query is assigned to at least one content module. The results of the query are displayed on two regions of the user&#39;s screen. On a first region of the user&#39;s display screen a list of information relating to the plurality of retrieved web sites is displayed. On a second region of said display screen, information from said at least one content module associated with the query is displayed.  
           [0009]    One feature of the present invention is to maintain a directory of web-page content modules and to algorithmically traverse the directory, based upon some user input, to synthesize content for a web-page.  
           [0010]    A module as used herein may be a discrete chunk of content so that combining one or multiple modules will in effect synthesize part or all of the content of a web page. For example, a user may issue as input the word “dolphins” and the invention will dynamically create a web page with various content modules related to dolphins. The exemplary method of the invention may traverse the directory containing the content modules and obtain modules which exactly correspond to the keyword “dolphins” if such modules exist in the directory. For example, the traversal may obtain content modules with pictures and links to dolphin shows. Alternatively the invention may obtain modules that do not directly correspond to the keyword “dolphins,” but are related to keyword, if such modules exist in the directory. For example, the directory traversal may obtain content modules related to marine mammals.

         [0028]    Displaying Content Over the Internet Based Upon Some User Input  
         [0029]    [0029]FIG. 1 illustrates by way of example a flow chart that represents a functional algorithm for generating content for display over the Internet based upon some user input. In this embodiment of the present invention, a user on a client system first sends a query to a server system ( 1 ). This query may be any textual input and/or keyword and/or phrase and/or search term etc.  
         [0030]    Generating a Subject Category Identifier  
         [0031]    The query is then algorithmically associated with a subject category identifier (shown in steps  1 - 12 ). In general, there may be four possible outcomes of the first pass of the algorithm: first, a single subject category identifier is obtained which is an exact match to the user input ( 15 ); second, a single subject category identifier is obtained which is an alternative match to the user input ( 17 ); third, multiple subject category identifiers are obtained which are alternative matches to the user input and the algorithm narrows the subject category identifiers to one ( 16 ); fourth no subject category identifier is found ( 7 ). FIG. 2 discloses another embodiment of generating the subject category identifiers ( 15 ,  16 ,  17 ,  7  on FIG. 1).  
         [0032]    Subject category identifiers associated with user input may be stored in two different tables; namely, an exact match table ( 3 ) or an alternative table ( 6 ). First, the algorithm checks the exact match table ( 2 ,  3 ) to determine if there is a subject category identifier that corresponds to the query. The subject category identifiers in the exact match table correspond to nodes in the content module data directory ( 13 ) directly relating to the user input. For example, if the user input is “dolphins” and the algorithm obtains a subject category identifier in the exact match table ( 3 ), the respective node in the data directory ( 13 ) associated with that subject category identifier may contain a content module directly relating to dolphins. Furthermore a subject category identifier obtained from the exact match table ( 3 ) may indicate the starting node point for traversing the content module directory ( 14 ) and determine the algorithm for traversing the data directory for additional content modules. If no corresponding subject category identifier is found in the exact match table for some user input ( 4 ), the algorithm checks the alternative table to determine a subject category identifier that corresponds to the query ( 5 ,  6 ). If a single subject category identifier in the alternative table is found associated with the user input ( 9 ,  10 ,  17 ), then this subject category identifier is used for the directory traversal for obtaining content modules ( 14 ). The subject category identifiers in the alternative match table correspond to nodes in the content module data directory ( 13 ) relating to the user input and may indicate the starting node point for traversing the content module directory ( 14 ) and determine the algorithm for traversing the data directory for additional content modules. If a plurality of subject category identifiers are found ( 9 ,  10 ,  11 ) associated with the user input the algorithm may provide the user a choice of different query options to narrow the subject category identifiers to one ( 12 ). After the user makes a selection from the given choices, the algorithm selects the single subject category identifier ( 16 ). It is also possible that the algorithm not find a subject category identifier ( 7 ,  8 ) in either the exact match table or the alternative match table. In this case, the directory of content modules is not traversed.  
         [0033]    Directory of Content Modules  
         [0034]    A directory of content is maintained on the server system in a data structure such as a data tree which can be traversed ( 13 ). The content information may be stored in a variety of data structures known to one skilled in the art or methods developed in the future. An algorithmic traversal is then performed on the data structure based upon the subject category identifier generated from the query ( 14 ), in order to determine content for displaying ( 20 ). The data structure may be a data tree wherein each tree node contains pointer(s) to web content modules and each node is associated with a subject category identifier. The data tree may be hierarchically arranged so that the specificity of the web content module referenced by the node is a subset of the more general web content module referenced by the parent node. As an example, a node, associated with a subject category identifier, may be associated with mammals, and may contain a pointer to a web content module relating to mammals. The children node(s) of that node, also associated with subject category identifiers, may be associated with particular mammals, and may contain pointers to web content modules relating to those specific mammals such as dolphins or elephants. The children node(s) of the dolphin, for example, also associated with a subject category identifier, may be associated with a particular type of dolphin and may contain a pointer to a web content module relating to that particular type of dolphin. This type of data arrangement is just one method of maintaining the web content module directory. The data structure can be a collection of multiple data structures, and these data structures can be separated and/or merged. An arbitrary number of web content modules can be used in order to collectively provide content for a web page. The traversal may start at a particular node, wherein the node&#39;s number is equal to the subject category identifier generated from the query. The traversal may move up or down the data directory, depending upon how the subject category identifier was generated ( 15 ,  16 ,  17 ), in order to obtain content modules related to the query. For example, if the user input “dolphins” generated a subject category identifier from the exact match table ( 15 ), the algorithm may first use the content module referenced by the node corresponding to that subject category identifier, and then traverse down the data tree to obtain more specific content modules. If, on the other hand, the user input “dolphins” generated a subject category identifier from the alternative match table ( 16  or  17 ), the algorithm may first use the content module referenced by the node corresponding to that subject category identifier, and then traverse up the tree to obtain more general content modules. The web page is finally synthesized with the content modules obtained in the process outlined by FIG. 1.  
         [0035]    [0035]FIG. 2 is an exemplary method diagram in accordance with one embodiment of the present invention, which illustrates by way of example a flow chart that represents a functional algorithm for generating identification numbers for associating with nodes in a data directory.  
         [0036]    [0036]FIG. 3 discloses the resulting web page from a subject category identifier obtained from the exact match table ( 15 ) from a query for “Britney Spears”. FIG. 4 discloses the resulting web page from multiple subject category identifiers obtained ( 11 ) from the alternative match table from a query for “bridge” wherein no content modules are obtained and the user is given a choice of different query options ( 12 ). FIG. 5 discloses the resulting web page from a subject category identifier obtained ( 16 ) after the user selects “Bridge on the River Kwai, The” from the interstitial page ( 12 ) represented by FIG. 4. FIG. 6 discloses the resulting web page from a single subject category identifier obtained from the alternative match table ( 17 ) from a query for “bridges”. FIG. 7 discloses the resulting web page from no match ( 7 ,  8 ) from a query for “loza12”. FIGS.  8 - 14  disclose additional details of processes for implementing the embodiment of the invention shown in FIG. 1.
