document: Mining data records in Web pages A large amount of information on the Web is contained in regularly structured objects , which we call data records . Such data records are important because they often present the essential information of their host pages , e.g. , lists of products or services . It is useful to mine such data records in order to extract information from them to provide value-added services . Existing automatic techniques are not satisfactory because of their poor accuracies . In this paper , we propose a more effective technique to perform the task . The technique is based on two observations about data records on the Web and a string matching algorithm . The proposed technique is able to mine both contiguous and non-contiguous data records . Our experimental results show that the proposed technique outperforms existing techniques substantially .
