摘要：In this paper studies the problem of extracting structured data from Web pages. The objective of the proposed research is to automatically extract data items/fields from records, and store the extracted data in a database. We formally define a template, and propo se a model that describes how values are encoded into pages using a template. For this purpose a new method to perform the task automatically. It consists of two steps, (1) automatically identify such data records in a page, and (2) automatically align and extract data items from the data records. In this paper we are using a partial tree alignment as a DOM tree in fivatech framework. Based on above two steps an unsupervised, page level data extraction approach is used to deduce schema and Template for each individual Deep Web site.
