For several years, there are commercially-operating companies that collect data collected, for example, from social media portals.

This data contains information collected from posts, entries, comments, recordings, etc. posted by millions of users of social media portals.

Data is collected and processed in Big Data database systems. Sentiment analysis carried out on these data allows you to generate reports that are used in business, for example in marketing.

From these reports, the clients of the above-mentioned technology companies learn, for example, about how the recognition of their brand changes over time, what opinions about the products and services offered, etc., dominate.

But if the Big Data database resources analyzed in this way are mainly information collected from social media portals, do the generated reports have the advantages of objectivity?

Considering the current resources of the Internet, are the majority of comments on products, services, companies, institutions, etc. being entered on various websites at the moment? Are comments posted on social media portals?
