Title: Modeling information interactions

Abstract: Click models, probabilistic models of the interaction behavior of search engine users, have been studied extensively by the information retrieval community in recent years. We now have a handful of so-called click models, parameter estimation methods, evaluation principles and applications of click models, that form the building blocks of ongoing research efforts in the area.

In the talk I will provide background material on click models and describe the state-of-art. In particular, I will describe recent neural models of interaction behavior. On top of that, I will describe challenges and research opportunities for modeling users’ information interaction behavior. These challenges arise in the context of modern search engine result pages, where direct answers lead to positive abandonment, that is, the situation where users are satisfied by the results offered on the result page without measurable interaction. Another challenge arise in the context of mobile search where interaction signals other than clicks, such as taps and pinches, need to be interpreted in a reliable manner.

The talk is based on joint work with Alexey Borisov, Aleksandr Chuklin, Artem Grotov, Julia Kiseleva, Ilya Markov, Pavel Serdyukov.
