Abstract(s)
The development of conversational agents has witnessed immense improvement in recent
years, being used in increasingly extensive and complex dialogues with the system users. Likewise, mobile health applications (mHealth) have found their space in the market, helping their
users achieve the goals they are aiming towards. But despite this growth on both fronts, there is
no unified structure of what is needed when building the architecture of a conversational agent
working in this area.
Based on the foundations built on the VASelfCare project, which uses Behavioral Change
Techniques in an intervention with the support of a Conversational Agent, this project aims to
define a Development Platform for a Proactive Conversational Agent that manages to help its
user achieve certain goals on a natural language dialogue, as well as define a Methodology for
the Development.
The project’s main idea is to achieve a level of abstraction that allows any system developed
with these principles to discuss any topic that is required from them. The Conversational Agent
must be proactive to be able to guide the dialogues with the user, applying Behavioral Change
Techniques when necessary to support them in achieving the objectives that the topic requires.
The development of the Proof of Concept was successful, managing to combine a Natural
Language Processing Service such as Dialogflow with databases and knowledge on the chosen
topic, achieving a base adaptable to any topic with representation in Ontology.
