Systems and methods for user-constructed hierarchical interest profiles and information retrieval using same

Abstract

Systems and methods for delivering Web content are provided. The systems and methods include a mechanism for providing interest data that may be applied to filter Web content at the provider side. A hierarchical data set of user-identified interests in received from the user's Web client. The hierarchical data set is parsed, and responsive thereto, one or more keyword attribute values are extracted from the hierarchical data set. The extracted keyword values are applied to filter content for delivery to a requesting Web client.

1 - 7 . (canceled) 
   
   
       8 . A computer program product embodied in a machine-readable medium for delivering a webpage, the computer program product comprising programming instructions for:
 receiving a hierarchical data set of interests identified by a user;   storing the hierarchical data set of interests in a database entry associated with the user;   parsing the stored hierarchical data set;   extracting one or more keyword attribute values from the stored hierarchical data set in response to the parsing and a pre-selected granularity value;   applying extracted one or more keyword attribute values to filter content for delivery to the user;   pre-populating a Web content search form page using extracted one or more keyword attribute values;   returning the Web content search form page to the user;   receiving the Web content search form page from the user, wherein the received Web content search form page includes one or more pre-populated data, one or more additional user-supplied search terms and at least one Boolean search indicator for determining the combination of search terms for performing a search; and   delivering at least one webpage that is personalized for the user according to the identified interests and the search.   
   
   
       9 . The computer program product of  claim 8  wherein the hierarchical data set comprises an XML document. 
   
   
       10 - 12 . (canceled) 
   
   
       13 . The computer program product of  claim 8  wherein, if no keyword attribute is associated with an interest, using a value attribute of the interest as a default keyword. 
   
   
       14 . The computer program product of  claim 8  wherein the granularity value corresponds to a root-to-leaf level in the hierarchical data set of identified interests. 
   
   
       15 . A data processing system for delivering a webpage comprising:
 a processor;   an application program recorded in a computer storage medium and executed by the processor for:   receiving a hierarchical data set of interests identified by a user;   storing the hierarchical data set of interests in a database entry associated with the user;   parsing the stored hierarchical data set;   extracting one or more keyword attribute values from the stored hierarchical data set in response to the parsing and a pre-selected granularity value;   applying extracted one or more keyword attribute values to filter content for delivery to the user;   pre-populating a Web content search form page using extracted one or more keyword attribute values;   returning the Web content search form page to the user;   receiving the Web content search form page from the user, wherein the received Web content search form page includes one or more pre-populated data, one or more additional user-supplied search terms and at least one Boolean search indicator for determining the combination of search terms for performing a search; and   delivering at least one webpage that is personalized for the user according to the identified interests and the search.   
   
   
       16 . The data processing system of  claim 15  wherein the hierarchical data set comprises an XML document. 
   
   
       17 - 19 . (canceled) 
   
   
       20 . The data processing system of  claim 15  wherein, if no keyword attribute is associated with an interest, using a value attribute of the interest as a default keyword. 
   
   
       21 . The computer program product of  claim 8  wherein the webpage is a portal page associated with the user and provided by a portal. 
   
   
       22 . The data processing system of  claim 15 , wherein the webpage is a portal page associated with the user and provided by a portal.
