Abstract: A method, apparatus and article of manufacture for updating a new node in a multidimensional scaling (MDS) database having an existing node. The new node is compared to the existing node to obtain a disparity value. A distance value is calculated between the new node and the existing node, a sum of differences value is calculated for the disparity value and the distance value, and a sum of squares value is calculated for the disparity value and the distance value. The position of the new node is modified according to the sum of differences value and the sum of squares value.

Abstract: A method for use in classifying, storage and retrieval of audiovisual information. The method uses the elements of a semantic description to describe arbitrary structure related to the audiovisual information. The method includes: (1) providing entities describing non-relational parts of the semantic description, the entities including a concept having a collection of properties of the audiovisual information, and (2) referencing one or more interior structures of the concept from all entities in the semantic description.
