There are many different forms of psychotherapy. Itemized inventories of psychotherapeutic interventions provide a mechanism for evaluating the quality of care received by clients and for conducting research on how psychotherapy helps. However, evaluations such as these are slow, expensive, and are rarely used outside of well-funded research studies. Natural language processing research has progressed to allow automating such tasks. Yet, NLP work in this area has been restricted to evaluating a single approach to treatment, when prior research indicates therapists used a wide variety of interventions with their clients, often in the same session. In this paper, we frame this scenario as a multi-label classification task, and develop a group of models aimed at predicting a wide variety of therapist talk-turn level orientations. Our models achieve F1 macro scores of 0.5, with the class F1 ranging from 0.36 to 0.67. We present analyses which offer insights into the capability of such models to capture psychotherapy approaches, and which may complement human judgment.more » « less

Pan, Xingyuan; Mehta, Maitrey; Srikumar, Vivek (, Proceedings of the 58th Annual Meeting of the Association for Computational Linguistics,)Various natural language processing tasks are structured prediction problems where outputs are constructed with multiple interdependent decisions. Past work has shown that domain knowledge, framed as constraints over the out-put space, can help improve predictive accuracy. However, designing good constraints of-ten relies on domain expertise. In this pa-per, we study the problem of learning such constraints. We frame the problem as that of training a two-layer rectifier network to identify valid structures or substructures, and show a construction for converting a trained net-work into a system of linear constraints over the inference variables. Our experiments on several NLP tasks show that the learned constraints can improve the prediction accuracy,especially when the number of training examples is small.more » « less

Li, Tao; Gupta, Vivek; Mehta, Maitrey; Srikumar, Vivek (, Proceedings of the Conference on Empirical Methods in Natural Language Processing (EMNLP))While neural models show remarkable accuracy on individual predictions, their internal beliefs can be inconsistent across examples.In this paper, we formalize such inconsistency as a generalization of prediction error. We propose a learning framework for constraining models using logic rules to regularize them away from inconsistency. Our framework can leverage both labeled and unlabeled examples and is directly compatible with off-the-shelf learning schemes without model redesign. We instantiate our framework on natural language inference, where experiments show that en-forcing invariants stated in logic can help make the predictions of neural models both accurate and consistentmore » « less
