Abstract
A content processing system determines content of input discourse. The content processing system includes a theme vector processor that determines themes in the input discourse. The theme vector processor identifies themes, including identifying the relative importance of the themes in the input discourse by generating a theme strength. The theme strength indicates relative thematic importance for the theme in the input discourse. A knowledge catalog, which includes static ontologies arranged in a hierarchical structure, is also disclosed. The static ontologies are independent and parallel of each other, and contain knowledge concepts to represent a world view of knowledge. The theme vector processor utilizes the static ontologies to generate a theme concept for each theme by extracting a knowledge concept from a higher level node in the hierarchical structure of a static ontology.
