Web Scraping
One of the biggest challenges encountered with big
data is the availability of data. It can be very difficult to find large data
sets that you are interested in analyzing. So the only alternative is to go out
and collect your own data, yet that is not as simple as it may sound.
If you need 10 gigabytes of data from twitter what are
you going to do? Are you going to go to twitter and manually copy and paste
thousands of comments into excel or notepad? I know I have gathered data in
that fashion before. There is another more time friendly technique you can use
to harvest data from the internet. That technique is called web scraping. Web
scraping simulates human interaction with a website typically utilizing HTTP
code. Its main task is to gather and organize data from a website or multiple
websites. The large majority of these programs will allow you to export the
data directly into your favorite spreadsheet program. By going through a
relatively short setup process you can create an file that will scrape huge
amounts of data for you and organize it neatly. Saving you hours of copy and
pasting. For a more in depth description of how web scraping works please refer
to the link below.
There are numerous programs that can be utilized for
web scraping. The technical knowhow needed to operate these programs vary. Some
of the programs require the user to program others have a 100% GUI interface. Provided
below is a short list of programs that perform web scraping and if they are
highlighted they are freeware. I think that this technique is a valuable item
to use whenever you are trying to gather your own data from the internet.
