| Abstract |
Generally, the database websites have provided the interfaces for giving users access their structured data. These data are usually represented in a form of data records in a coherent region of a result page. However, the page usually contains not only the data region, but also other extraneous ones. Therefore, the important tasks for extracting data records from these semi-structured web pages are identifying the relevant data regions and ignoring the irrelevant regions. To figure out the stated problem, This paper proposes a region extractor to be a preprocessor tool for helping an information extractor to locate and extract the relevant data records from web pages. Most existing works analyze the DOM tree of an input page in a top-down manner. In another way, the proposed method traverses the DOM tree in the bottom-up direction that the similarity of the leaf nodes are analyzed prior to find a set of data items. After that, their parent nodes are recursively analyzed for identifying data records and data regions respectively. The proposed method is completely unsupervised and maintenance-free wrapper. For performance evaluation, it is empirically tested on 15 real-world websites. Experiments show that the proposed method achieves 94.37% accuracy of data record extraction and outperforms the well-known top-down method, DEPTA (55.39%). |
