Structuring E-Commerce Inventory
Karin Mauge, Khash Rohanimanesh, Jean-David Ruvini · 2012
Large e-commerce enterprises feature millions of items entered daily by a large variety of sellers. While some sellers provide rich, structured descriptions of their items, a vast majority of them provide unstructured natural language descriptions. In the paper we present a 2 steps method for structuring items into descriptive properties. The first step consists in unsupervised property discovery and extraction. The second step involves supervised property synonym discovery using a maximum entropy based clustering algorithm. We evaluate our method on a year worth of e-commerce data and show that it achieves excellent precision with good recall. 1
