Screenshots, known for years as capturing Graphical User Interface by means of print screen button or capturing software, is not only beneficial for creating user guide or user manual document, but also for reverse engineering process. This paper presents a new way of capturing the data appear on a screen by creating the ontology of its interface. Data capturing based on the interaction style o...

Observational studies on couple interactions are often based on manual annotations of a set of behavior codes. Such annotations are expensive, time-consuming, and often suffer from low inter-annotator agreement. In previous studies it has been shown that the lexical channels contain sufficient information for capturing behavior and predicting the interaction labels, and various automated proces...

In this paper we develop a two-step survival time approach – a discrete logit model with survival time dummies – that allows for time-varying explanatory variables and interval censored data. Our empirical analysis reveals that the twostep approach outperforms the benchmark logit model with respect to out-ofsample prediction accuracy. Survival time, however, does not play an important role. The...
