La profesora Dña. Lili Aunimo, de la Universidad de Haaga-Helia (Finlandia) y participante de Ulysseus European University está realizando una estancia corta en la Escuela e impartirá el jueves 22 de junio a las 10:30 en la Sala Multiusos el seminario titulado Chatbots: Experiments in dialogue modelling, interaction style and expert work automation, cuyo resumen es el siguiente:

Chat bot services are in place in a variety of domains and tasks such as sales and customer support services in business, student counselling in education and medical services in healthcare. There is abundant data available for modelling chat dialogs because online chat has been a popular way of communication between humans already for several decades. There are also innumerable other valuable digital resources that can be exploited when building a chatbot, including pretrained large language models. We tested and evaluated several ways of preprocessing and modelling of chat dialogs in Finnish. As a result, we found out that the best accuracy is achieved using uncasing and spell-checking in the preprocessing phase and a BERT model pretrained with Finnish in the modelling phase. Despite the extensive use of chatbots, there are still many open research questions. One example is the effect of chatbot interaction style on user experience and emotions. Our initial study suggests that chatbots including small talk are less likely to elicit negative emotions, whereby emojis and emotional statements issued by chatbots do not play a significant role on the user’s emotional responses. We also present how medical expert work may be partially automated and made more interesting as input for routine conversation is handled by a chatbot.

Además de impartir este seminario, a la Dra. Aunimo le gustaría contactar con investigadores que trabajen en el campo de HCI, NLP o business analytics. Asimismo, le gustaría estudiar las posibilidades de intercambio Erasmus en primavera de 2024.
