Many researchers in the field of requirements engineering are now focusing on eliciting requirements only from market influencers, that is, people who have a great influence on the market success of products. However, acting on the requirements expressed by customers without validating them can cause a product to fail in the market. Therefore, the importance of a requirement proposed by a customer should be validated by various other customers. Social Network Services (SNSs) are an important tool for validating customer requirements.
