Abstract
The Websites are an important source of data now days. There has been different types of information available on it. This information can be extremely beneficial for users. Extracting information from internet is challenging issue. However the amount of human interaction that is currently required for this is inconvenient. So, the objective of this paper is try to solve this problem by making the task as atomic as possible. Existing methods addressing the problem can be classified into three categories. Methods in the first category provide some languages to facilitate the construction of data extraction systems. Methods in the second category use machine learning techniques to learn wrappers (which are data extraction programs) from human labeled examples. Manual labeling is time-consuming and is hard to scale to a large number of sites on the Web. Methods in the third category are based on the idea of automatic pattern discovery. For extracting information from web firstly we have to determine the meaningfulness of data. Then automatically segment data records in a page, extract data fields from these records, and store the extracted data in a database. In this paper, we are given method for an extracting data from SEC site by using automatic pattern discovery.
