What is data mining?

Data mining is the process of analyzing information to identify patterns and trends in order to make data-driven decisions. It‘s often conflated with web scraping, which is the process of extracting such data from the web. While people do use the term data mining to mean both data extraction and data analysis, the key difference is that data mining is what follows data extraction. In other words: you can scrape web data without mining it, but you can’t mine web data without scraping it.

In a nutshell

What’s the difference between web scraping and data mining?

Web scraping = data extraction
Data mining = data analysis


Data mining social media

So, why do people mine social media? Because it helps business owners to dive deeper into market demographics. Data mining Facebook groups and profiles, for example, enables organizations to offer products or services based on people’s personal choices, life events, and key goals. They can identify preferred products, spending patterns, and consumer behavior and help to better understand the consumer and create a personalized bond. Facebook or Instagram data mining can help to formulate the ideal consumer persona, forecast emerging market trends, and gain a competitive edge over similar businesses.

Scraping and mining social media data is legal, but that’s not to say you can accumulate personal data without having a legal basis for doing so. Keep your web scraping and data mining legal and ethical by crawling and extracting only publicly available information.

What data can I extract from Facebook?

With a Facebook scraping tool, you can crawl, extract and mine all publicly available data from Facebook pages, such as:

  • posts
  • likes
  • comments
  • reviews
  • contact details
  • profiles
  • addresses

What are the most effective tools to mine Facebook data?

There are two ways you can scrape data for Facebook mining:

a) The Facebook API
b) A Facebook web scraper


Data mining with the Facebook API

The Facebook API gives developers access to core elements of Facebook functionality. It provides a way to retrieve information about a user, showing their recently uploaded photos or accessing information about friends who use the same application. This enables applications to provide richer social experiences to their users based on the data that Facebook already has about that person.


This functionality is implemented by showing the user a dialog that tells them which parts of their data the application would like to access, asking the user to either authorize or deny permission to the application. If the user accepts, the application is supplied with an "access token". This token encodes information, such as the application's unique identifier on Facebook, and the elements of the user's data that the application has been allowed to access.

The token must be supplied to the Facebook API for validation every time a request is made for user data. Access tokens are only valid for a relatively short period of time, so a method is provided for an application to supply an old access token in exchange for a new one. This means that if the user were to revoke the permission that the application had to access their data, the request for a new access token will be denied and the application will no longer have access to that user‘s data.

The Facebook API is quite restrictive. Facebook’s rate limits are strictly enforced, so you won’t be able to extract a lot of information in a short period of time and you can easily get your API key blocked.
