    Abstract: Disclosed is a process for ranking semantic web resources, comprising the steps of; establishing an RDF knowledge base using diverse tools that support the establishment of ontologies; setting, by class, object and subject weights for an object type attribute and a weight for a data type attribute on the schema composed of classes that constitute a domain and of attributes that describe relationships between these classes; extracting from the RDF knowledge base an RDF triple composed of three portions, i.e., a subject, a predicate and an object; creating a weight matrix of class-oriented attributes based on a set weight and the extracted RDF triple; and operating the created weight matrix of class-oriented attributes to calculate a first eigenvector and obtain a vector for ranking scores of resources.
