Method and system for merging hierarchies

摘要

A system and method for merging product information from a first hierarchy into a second hierarchy. A Naive Bayes classification model is generated using both text data and attribute (numerical) data pertaining to products in the second hierarchy. Then, products in the first hierarchy are placed into the second hierarchy in accordance with the model. Preferably, the placement of the products in the second hierarchy depends in part on their grouping in the first hierarchy, on the intuition that if two products were grouped together in the first hierarchy they have a higher likelihood of being grouped together in the second hierarchy as well.
