System and method for creating a semantic web and its applications in browsing, searching, profiling, personalization and advertising

A method for generating targeted content, comprising steps of:

• (a) receiving a classifier associated with a data set;
• (b) retrieving WorldModel-based extraction information associated with the received classifier;
• (c) extracting metadata associated with the data set based upon the retrieved extraction information;
• and
• (d) accessing content information based on the metadata for presentation to a user, wherein the step of accessing content information comprises steps of:
• (i) creating a markup language string that represents the classifier;
• transmitting the markup language string to a content provider together with user profile information derived from the metadata;
• and
• (ii) receiving a URL reference to semantically related media content from the content provider;
• (e) receiving from a user a selection for a media asset from a query result;
• providing a player for the media asset in a new instance of a Web browser which contains a Webpage related to the source of the media asset;
• wherein the step of receiving a URL reference to semantically related media content comprises receiving advertisement information tailored to the Webpage in the new instance of the Web browser.

A system for generating metadata associated with a data set, the system comprising:

• (a) a processor;
• (b) a data store coupled to the processor and storing WorldModel-based extraction information;
• the processor being programmed to
• retrieve a classifier associated with a data set;
• retrieve WorldModel-based extraction information including at least one attribute identifier correlated with pattern information associated with a received classifier;
• extract metadata associated with the data set based upon the retrieved extraction information;
• and
• storing in the data store the extracted metadata which is correlated with an identifier corresponding to the data set.
