Ludwig Wittgenstein's theories of language—particularly his concepts of language games and the meaning of words as their use—have direct, demonstrable applications in modern computational linguistics, natural language processing, and pragmatic communication design.
The claim is specific, empirical, and contestable regarding whether philosophical theories (Wittgenstein's) have practical applications in a specific field (linguistics). The retrieved papers provide direct evidence of Wittgenstein's concepts being operationalized in natural language interfaces (Paper 0) and pragmatic linguistic applications (Paper 11). Therefore, the balance of evidence clearly supports the claim.
