Examining sentiment in team communications can provide information about trust among teammates. Natural language processing (NLP) models provide an efficient means of sentiment analysis. However, military teams and other professional teams use language that differs from what NLP models are trained on, leading to potentially inaccurate sentiment analysis. This study investigates the novel application of two advanced NLP models, DistilBERT and GPT-2, for sentiment analysis of expert military teams conducting AI-supported combat missions in a high fidelity simulation environment. Our fine-tuning process resulted in improved sentiment classification accuracy. The sentiment measures also correlated with measures of team trust and trust in the AI systems, providing valuable insight into the relationship between sentiment and trust in human-AI teaming scenarios. The generalized approach we describe may be useful for adapting sentiment analysis and NLP techniques to military teams, and may help measure trust dynamics and team states in human machine integrated teams.

Truth in Wittgenstein′s Later Philosophy. In this paper I attempt to examine Wittgenstein′s understanding of truth in his later period. In doing so, I orient myself primarily on the remarks published as Philosophical Investigations and On Certainty. My primary aim in the destructive part is to show that his later philosophy neither espouses a redundancy and deflationary, nor an epistemic and anti-realist conception of truth. Both strands of interpretation are strongly represented in the debate. An examination of Wittgenstein’s remarks on the correspondence theory of truth will also shed some light on his thoughts about truth. Furthermore, in the preceding constructive part of this paper, I will try to demonstrate that (1) for Wittgenstein there is a strong link between truths that we accept based on our certainties and our use of the term “truth” and (2) that skepticism about truth, which claims that all accepted truths in our Weltbild (“world-view”) could be actually false, fails to give any meaning to its use of “truth”. This culminates in Wittgenstein′s insight, that the question of what truth is can only be answered relative to the Weltbild. Therefore, talking about truths that transcend our Weltbild becomes nonsense.
