For the purpose of this work, a dataset is constructed by consulting different fact-checking organizations. It contains debates and speeches in the domain of politics. Thus, even the ability of this approach is evaluated on this domain. The approach starts with extracting sentence-level and context features from the sentences, and further on with the classification of the sentences based on these features. The feature set and context features are chosen after several experiments, based on how well they differentiate check-worthy statements....
