If we present the products as the attribute name and value pairs, it will improve the effectiveness of many applications. In this paper, we propose an adaptive template based method to simultaneously extract the product attribute name and value pair from Web pages. The titles of Web pages are used to assist the unsupervised template construction. And the template ranking strategy ensures the correct templates of every Web page are selected. Our approach contains four key steps: 1) construct

The experimental corpus is collected from two domains: digital camera and mobile phone. Experiments show the precision of 94.68% and recall of 90.57% can be got by our method.
