KNOWLEDGE BROADCASTING AND CLASSIFICATION SYSTEM

Embodiments of the system may utilize a Knowledge Broadcasting System for specifying content metadata and locating Internet documents. In this instance embodiments of the invention comprise an improved manner of specifying the content of an Internet document in such a way that the users of the system are able to retrieve relevant Internet documents. This is accomplished using a three-tiered search engine where the first-tier is denoted as a category search, the second tier is denoted as a context search, and the third-tier is denoted as a keyword search. At each step relevant information is filtered out and the focus of the search is narrowed. In the general search, the user narrows the focus of the search by selecting a hierarchical definition.
