Introduce web scraping,and web scraping with FMiner
What is web scraping
Web scraping means crawling websites and extracting contents on the pages according to some rules, and storing the data into database or files.
In our new world of technology and easier access to information through the internet and the media we are now turning to technology once again to help us collect this information. That technology is called Web Scraping, sometimes called Web Harvesting, although Web Harvesting is slightly different.
You need a software to scrape the web to pick out information you require from various URL’s giving you the data you need. Web scraping is likened to web browsing, however; instead of manually looking through a website to gain information that you can see, web scraping allows you not only to automate this, but to scrape data from the site that is hidden in background code we don’t see.
Examples of web scraping /web harvesting are the insurance comparison websites. If they were to search the net themselves for all the different types of home insurance, the information would be out of date before they could publish it. By using web scraping software, they can continually keep their site up to date giving the latest prices from several different companies.
Many websites may post up information in formats that are basic texts at the forefront. However, there is hidden data in the background, which can only be accessed through code, HTML language, for instance. Consider a government official website, they might show that crime rate is decreased in a certain area to show that a certain methodology is working, However; in the background, the coding is still there showing that it increased in the next state along.
