We propose a novel semantic anno- tation type of assigning truth values to predicate occurrences, and present TruthTeller, a standalone publicly- available tool that produces such annota- tions. TruthTeller integrates a range of semantic phenomena, such as nega- tion, modality, presupposition, implicativ- ity, and more, which were dealt only partly in previous works. Empirical evaluations against human annotations show satisfac- tory results and suggest the usefulness of this new type of tool for NLP.
