<p>The invention is an ontological- content-based method for filtering and ranking the relevancy of items. The filtering method of the invention utilizes a hierarchical ontology, which considers the distance, or similarity between concepts representing each user and concepts representing each item, according to the position of related concepts in the hierarchical ontology. Based on that, the filtering algorithm computes the similarity between the items and users and rank-orders the items according to their relevancy to each user. The method finds general use in the fields of information filtering and publishing, specifically the production of electronic newspapers for which the invention provides methods of filtering and ranking the relevance of news content to specific readers in order to allow production of personalized electronic newspapers.</p> |
