Identifying complex behavior in human interactions for observational studies often involves the tedious process of transcribing and annotating large amounts of data. While there is significant work towards accurate transcription in Automatic Speech Recognition, automatic Natural Language Understanding of high-level human behaviors from the transcribed text is still at an early stage of development. In this paper we present a novel approach for modeling human behavior using sentence embeddings and propose an automatic behavior annotation framework. We explore unsupervised methods of extracting semantic information, using seq2seq models, into deep sentence embeddings and demonstrate that these embeddings capture behaviorally meaningful information. Our proposed framework utilizes LSTM Recurrent Neural Networks to estimate behavior trajectories from these sentence embeddings. Finally, we employ fusion to compare our high-resolution behavioral trajectories with the coarse, session-level behavioral ratings of human annotators in Couples Therapy. Our experiments show that behavior annotation using this framework achieves better results than prior methods and approaches or exceeds human performance in terms of annotator agreement.
