In the current era of unprecedented explosion of information, people no longer worry about the lack of information, but pay for the screening of a large number of useful information.
So how to collect useful information? There are RSS, blogs and other useful information, but they do not fully meet our needs because a lot of information is not provided in the form of formatted data. But our engineers came up with a method to search information exactly and therefore a large number of vertical search sites have appeared. We do not know how they are implemented, but we can precisely collect data as well.
What is web harvesting
Web harvesting, also known as web scraping, is the process of data collection from target web pages on the Internet by specialized programs or software and export the data extracted to the place of your choice. Web Harvesting still mainly focus on web content pages that are based HTML / XML. You may need to grasp some technologies like XQuery and RegEx( Regular Expression) that can help you screen the content of text / XML documents and thus to collect the exact information.
Octoparse, a web harvesting tool
Octoparse is an easy-to-use and powerful software for web harvesting. Unlike search engines that are to crawl the entire Internet , Octoparse is a typical web harvesting tool that you need to harvest information from the web by configuring simple rules.
Octoparse enables you to collect data from the web page, including the hidden data that is not displayed on the screen. It will go over all the web pages in both depth and breadth based on its algorithm.
