Large e-commerce enterprises feature mil- lions of items entered daily by a large vari- ety 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 su- pervised 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 ex- cellent precision with good recall.
