Crawling social networks is a relatively new concept, one which needs to be performed carefully for ensuring compliance with data privacy norms of various social media sites. Most of these sites control the access of information to crawlers (as well as individuals) via APIs,
though publicly available, non-sensitive information can also be extracted otherwise. Social media data providers
use crawlers for extracting specific information
on the basis of specific keywords, profiles, geographies, groups and other demographics
. This kind of targeted information is very valuable for companies as running analytics
sentiment becomes a rather simple step as one of the most important steps that can make or break the analysis
is social media data acquisition.
