In social networks users contribute with their opinions and knowledge, forming a huge information repository. The use of this information by companies, which consider social networks as a way of promoting their products, has been rising. This study, through the use of Sentimental Analysis, sustain the conclusion that the information obtained from social networks (Facebook and Twitter) can be used to determine values that can be obtained in the commercialization of goods or services to be launched in the market.
