Method of efficient migration from one categorization hierarchy to another hierarchy

摘要

A method of efficiently migrating data from one categorization hierarchy to a new hierarchy. A mapping is created which describes where a document in one hierarchy will be placed in a new hierarchy. The classifier of the first hierarchy is merged with this mapping to act as a classifier for the second hierarchy. Cases from the first hierarchy are classified in the new hierarchy using this merged mapping. In another embodiment, a training set is designated from a first hierarchy and mapped to a second hierarchy. Using machine learning, a classifier for the second hierarchy is derived and used to classify subsequently migrated cases. Migration of data using the present invention is more accurate as fewer human errors are generated. The present invention can act as a virtual classifier for multiple hierarchies in an organization, providing updated categorization information for multiple hierarchical databases.
