Tarski's Theory of Truth and Cyberspace problem

Verifying of sentences in cyberspace (such as internet) is very important. Because of the wider range of its information and availability, cyberspace is one of the most important tools for obtaining information. With all the benefits, this information will not be efficient and reliable if we don't have a way to measure the accuracy of them. The availability and vastness of it can change the reality by cyberspace's sentences, which we call them "Fact Maker sentences". Such sentences make a reality by themselves, unlike other sentences that just reflect external realities. Evaluation of the truth of these sentences based on the corresponding theory and Tarski's Theory of Truth is the main purpose of this paper. These theories will have been challenged by the "Fact Maker sentences".
