Schouten, D.G.M. (author), Massink, Pim (author), Donker, Stella F. (author), Neerincx, M.A. (author)In this study, we attempt to specify the cognitive support behavior of a previously designed embodied conversational agent coach that provides learning support to low-literates. Three knowledge gaps are identified in the existing work: an incomplete specification of the behaviors that make up ‘support,’ an incomplete specification of how this...journal article 2020

Qiu, S. (author), Gadiraju, Ujwal (author), Bozzon, A. (author)This demo presents TickTalkTurk, a tool that can assist task requesters in quickly deploying crowdsourcing tasks in a customizable conversational worker interface. The conversational worker interface can convey task instructions, deploy microtasks, and gather worker input in a dialogue-based workflow. The interface is implemented as a Web...conference paper 2020

Bălan, Alexandru (author)Nowadays, most users access the web through search engine portals. However, information needs can often be ill-defined or too broad to be solvable by a list of results the user has to scroll through, which implies that he is most likely required to refine the need by himself to reach the desired result. In recent years, researchers have...master thesis 2019

Tielman, M.L. (author), Neerincx, M.A. (author), Pagliari, Claudia (author), Rizzo, Albert (author), Brinkman, W.P. (author)Background: Digital health interventions can fill gaps in mental healthcare provision. However, autonomous e-mental health (AEMH) systems also present challenges for effective risk management. To balance autonomy and safety, AEMH systems need to detect risk situations and act on these appropriately. One option is sending automatic alerts to...journal article 2019

Bapat, Rucha (author), Kucherbaev, P. (author), Bozzon, A. (author)Chatbots are text-based conversational agents. Natural Language Understanding (NLU) models are used to extract meaning and intention from user messages sent to chatbots. The user experience of chatbots largely depends on the performance of the NLU model, which itself largely depends on the initial dataset the model is trained with. The training...conference paper 2018
