semantic net information creation (user-driven by providing …) information aggregation (user-driven by demanding, searching …) ece 627, winter ‘13

ontology information creation centralized, hierarchical categorization … … but it enables cross-application aggregation and value-added services ece 627, winter ‘13

ontology for tag data information creation enables utilization of tag data across multiple systems for: tag search collaborative filtering query with tags ece 627, winter ‘13

information aggregation issues how to integrate users’ contributions of unstructured content with structured data? how to create value form the web content? ece 627, winter ‘13

information aggregation solutions? combining hierarchical information (ontology) with spontaneous contributions (tags) site independent activities (spanning across multiple sites) integration-based search semantic web + social web ece 627, winter ‘13
