Structured Data Extractor (sde) is an implementation of DEPTA (Data Extraction based on Partial Tree Alignment), a method to extract data from web pages (HTML documents). DEPTA was invented by Yanhong Zhai and Bing Liu from University of Illinois at Chicago and was published in their paper: "Structured Data Extraction from the Web based on Partial Tree Alignment" (IEEE Transactions on Knowledge and Data Engineering, 2006). Given a web page, sde will detect data records contained in the web page and extract them into table structure (rows and columns).
