For this reason, the evaluation, distribution and use of the mining rent plays a central part in the mining city’s development ...
Manganese nodules on deep ocean floor have received attention as future resources for Co, Ni, Cu, and Mn these 40 years. The mining and metallurgical processing technologies studied these 40 years have been reviewed and re-examined on the basis of current interests, technologies, and economies by the author. The preliminary results of economic evaluation at the three timings, such as the last 1...

A method for extracting new implicit knowledge from ontologies by using an inductive/deductive approach is presented. The new extracted knowledge takes the form of If-Then rules annotated with a weight. Such rules, termed Influence Rules, specify how the values of the properties bound to a collection of concepts may influence the values of the properties of another concept.The technique, that c...
