Epaminondas has spent many years in investigating ways to alleviate the tasks of interpreting, explaining and understandably communicating computational artefacts (e.g., algorithms, data, knowledge) with a variety of user types and personas.  Most noticeable stations of this explorative journey has been the design and implementation of a metadata driven visual query language, a human-computer interactive automaton and parser predicting user querying intention, a language and model for adaptive ontologies. His research culminated in prototypes being applicable to a variety of disciplines and real world projects such as retrieval of scientific and statistical databases for ozone hole research over the Arctic, natural language based querying and processing, as well as Web based decision trees as an e-consultation system in health care. Epaminondas did also apply Web and text mining techniques for competitive business intelligence within the context of Innovate UK funded initiative. Currently, Epaminondas is affiliated with the School of Physics, Engineering and Computer Science, University of Hertfordshire, UK, investigating human oriented explainable and interpretable AI/ML, such as natural language (conversational, dialogue) based systems and knowledge discovery from source code mining, as a contribution to responsible and trustworthy AI.
