We present Subgroup Detector, a system for analyzing threaded discussions and identifying the attitude of discussants towards one another and towards the discussion topic. The system uses attitude predictions to detect the split of discussants into subgroups of opposing views. The system uses an unsupervised approach based on rule-based opinion target detecting and unsupervised clustering techn...

Few authors would not be pleased when discussants implement their methods or follow-up on their ideas. It is therefore a professional joy to see every discussant doing both! Our heartfelt thanks go to all discussants, and to the Executive Editor, Ed George, for bringing us such joy! Incidentally, the three discussions cover nicely the three main parts of our paper. Zheng and Lo’s discussion cen...

I thank the discussants for their kind remarks, insightful comments on present state and future directions of field, many references they cite. Having no disagreements with them, will confine my rejoinder to a few issues that contributions have highlighted me.

We thank the editor Professor David Steinberg for organizing this stimulating discussion. We are also grateful to all the discussants for their constructive comments about the method proposed in our paper (denoted as QZW hereafter). Profile monitoring is a relatively new research area; but, it has a profound application background (cf., Wang and Tsung 2005, Woodall et al. 2004). Due to the fact...

Abstract Current formal dialectical models postulate normative rules that enable discussants to conduct dialogical interactions without committing fallacies. Though the for conducting a dialogue are supposed apply between actual arguers, they exception theoretically motivated. This creates gap model and reality, because participants typically leave important content-related elements implicit. T...

At an event focusing on population-health approaches to the opioid epidemic, discussants agreed that better coordination of care, community involvement in finding solutions, and more consistent use of improved pain-control options are required.

We are deeply grateful to the discussants for providing constructive and stimulating comments and suggestions. Our paper gives a survey of recent optimality and adaptivity results on estimating various families of structured covariance and precision matrices in the high-dimensional setting, with a focus on understanding the intrinsic difficulty of the problems. To achieve this goal, we present ...
