How Does This Scraping Work?
So let’s see how social media data scraping takes place, the first and the foremost thing is to know that it runs on a piece of code that is called a scraper. As it runs, the “Get” query rolls out to extract the HTML data coming from the API library on Facebook or any other social channels.
Subsequently, algorithms analyze a string of symbols, either in natural language or computer language or models in the Document Object Model (DOM) structure. This parsing process determines nodes (an object representing a part of the document). Then, it creates a node processor to show output in a normalized format. In simple words, the scraper comes into play, filtering through the data to pick up the requisite data sets. Once the requirement is fulfilled, the data is translated into a specific format.
In brief, a code is used to:
1. Extract data from APIs
2. Store the captured data
3. Recognize unique HTML site structures
4. Extract and transform data

Requirements For Social Media Scraper
Social media scraper is a program that requires:
– Software or scripts of codes that carries out through an API or web interface
– Variety of open source projects implemented in various programming languages, such as Java and PHP.
Challenges faced by data miners during social media scraping
– HTML 5 built social channels accept unique elements.
– Developers do not follow style guides, which cause anomalies or errors.
– Several different layouts of various social media platforms cause interruptions.
– Major quantity of comments, ads and navigation elements can act as a challenge.
– Size of the image on a particular channel may vary from its source code.
– Several different languages can be outcome as a big barrier in different locations.
– Few social channels update their layouts later, which require changes in scraping program subsequently.
– Modification in encoding can interrupt the circulation of a request.
– At the time of granular inspection of HTML, header signatures go through comparing funnel. This funnel investigates whether a visitor is human or a bot.
– It seems difficult to remove out bots without a CAPTCHA, attempting to pass through successfully like a human being.
– Intrusive rate of requests and illogical browsing patterns are difficult to be blueprinted, that can be determined as malicious behavior.
