Nowadays, artificial intelligence is one of the most important research areas for the technological development of many disciplines. Although it has grown exponentially in recent years, understanding of how it works is minimal for most people. Consequently, its use in decision making activities is limited, as evidenced in the Artificial Intelligence Index Report 2023 [1]. According to this report, the percentage change in the response of artificial intelligence assimilation by industry and activity between 2021 and 2022 has been -15% and -13% for marketing and sales activities, and product and/or service development, respectively. In view of this, we propose the design of a model to explain the basic components of a system based on artificial intelligence through a conversational chatbot developed in English. Thus, the explanation is provided in a simple format (text) and through an interactive manner (conversation). The explanatory model is based on the XAIO ontology, proposed in this study, and developed from two ontologies of machine learning and explainable artificial intelligence. Using a natural language generation model from structured data, the explanatory model generates natural language explanations based on the knowledge described in the triplets of the XAIO ontology. For evaluation purposes, a conversational chatbot was implemented. This chatbot uses a natural language understanding model to identify intentions and entities. Then it uses ontology queries build from the intentions and entities to get the ontology triplets. Regarding quantitative evaluation, an average BLEU of 76.97 was obtained, which indicates a good performance in the task of natural language generation from structured data. Likewise, explainable artificial intelligence systems were developed with chatbot for user testing and a SUS of 69 was obtained, indicating above-average usability. Finally, a qualitative evaluation was also carried out to obtain the participants' feedback about the systems. They mainly pointed out the coherence at the time of answering, the simplicity of the answers and the friendly interaction with the chatbot.
