Abstract:	We manually generated 1,500 positive correspondences, 500 for each product category: phones, headphones, and televisions. For each product of the product catalog at least one positive correspondence is included. Additionally, to make the matching task more realistic the annotators also annotate closely related products to the once in the product catalog like: phone cases, TV wall mounts or headphone cables, ear-buds, etc. Furthermore we created additional negative correspondences exploiting transitive closure. As all products in the product catalog are distinct, we can generate for all product descriptions contained in web pages, where a positive correspondence exist to a product in the catalog, for all other products in the catalog a negative correspondence to this product on the web page. Using the two approaches we ended up with 73,500 negative correspondences.
