Absztrakt :
There is an economic and political need to learn and know more and more
information about customers, and the social media has recently become the most
powerful tool for interaction with people. Customers became users in the social
media, who express their opinion and share it with not only companies but also other
users. Since a huge amount of reviews, opinions and comments appeared, there is
a necessity to extract, aggregate, and analyse them; these are the aims of sentiment
analysis. In this paper the technological details of sentiment analysis are presented.

based on data mining, but steps of text preprocessing with tokenisation, stemming,
filtering is an additional important phase before the data mining procedure. The
correctness of sentiment analysis solutions can be measured by different validation
methods. At the end of the paper the final conclusion is presented.
