Abstract: A method and apparatus for identifying the focus of a document, in a natural language processing application, the natural language processing application comprising a hierarchical concept tree having a plurality of nodes, each node being associated with a term, the method comprising the steps of: mapping an input document to nodes in a concept tree to determine a number of occurrences of a term in the input document which also occur at a node in the concept tree; weighting each node in the concept tree, depending on the determined number of occurrences of the term in the input document and a determined value assigned to each node in the concept tree; traversing the concept tree to identify a heaviest weighted path, in dependence on the weighting of each node in the concept tree; and determining the focus of the input document by identifying a node having the heaviest weight along the most heavily-weighted path.

Abstract: The water wheel motor consisting of the outlet device (1) located in front of the wheel (5) and of the drain device (6) located under the wheel (5), which can rotate on the rotation axes (18) and on which the isobaric paddles (4) are fixed. All points of the wheel (5) and of the isobaric paddles (4) are in the bigger distance or in zero distance above the plane (21), which is identical with the plane (19) or lower and at the same time parallel to the plane (19) limiting the upper level of the drain device (6) space containing water. The axis (2) of the outlet device (1) is directed on the isobaric paddles (4) and the rotation axis (18) of the wheel (5) is in the vertical, horizontal or oblique position.
