Abstract

A document taxonomy alignment system and method, relying on document glosses and utilizing a soft ontology expansion. An all-new hierarchical leaf node can be created expressly for the purpose of better aligning the plurality of document taxonomies in question. A small but valuable subset of the nodes created by soft ontology expansion turn out to capture some otherwise unmappable taxonomy nodes, and thereby have the effect of classifying the documents better than would any pre-existing node in any one of those taxonomies.

Claims

1. A method for mapping a taxonomy to at least one other taxonomy, the taxonomies including concepts for organizing information, the method comprising:

reviewing the taxonomy;

finding an expanded concept node that is instantiated disproportionately in the document glosses of an unmapped node of the taxonomy;

determining if the expanded concept node is instantiated in documents not classified at a leaf node in the at least one other taxonomy; and

creating a new node with the unexpanded concept and place the relevant documents under the new node if the expanded concept node is instantiated in documents not classified at a leaf node.

2. A computer readable medium having computer executable instructions recorded thereon for mapping a taxonomy to at least one other taxonomy, the taxonomies including concepts for organizing information, the instructions comprising:

instructions for reviewing the taxonomy;

instructions for finding an expanded concept node that is instantiated disproportionately in the document glosses of an unmapped node of the taxonomy;

instructions for determining if the expanded concept node is instantiated in documents not classified at a leaf node in the at least one other taxonomy; and

instructions for creating a new node with the unexpanded concept and place the relevant documents under the new node if the expanded concept node is instantiated in documents not classified at a leaf node.

3. A system for mapping a taxonomy to at least one other taxonomy, the taxonomies including concepts for organizing information, the method comprising:

means for reviewing the taxonomy;

means for finding an expanded concept node that is instantiated disproportionately in the document glosses of an unmapped node of the taxonomy;

means for determining if the expanded concept node is instantiated in documents not classified at a leaf node in the at least one other taxonomy; and

means for creating a new node with the unexpanded concept and place the relevant documents under the new node if the expanded concept node is instantiated in documents not classified at a leaf node.
