UXON: User eXperience Ontology Network based system

UXON is an ontology-based system to support user experience assessment in the context of an immersive experience application for large events. It aims to automate the user experience evaluation process, with data collected through indirect observation and the use of metrics, and to make the measurement results available in the form of tables and graphs, allowing the evaluator to analyze them and generate evaluation reports on immersive experiences.

Undergraduate Project

UXON was developed in the context of a undergraduate project (Manso, 2022) supervised by the author of HCI-ON. UXON uses a fragment of HCI-ON that includes concepts from HCI Ontology (HCIO), HCI Evaluation Ontology (HCIEO) and also from the Core Ontology on Measurement (COM) of SEON.

UXON's Ontology-Oriented Developement

The HCI-ON extract played a fundamental role. At development time, it contributed to understanding the application domain (i.e., UX evaluation) and defining UXON’s business (translated into business rules and algorithms) and application logic. It also contributed to defining UXON’s conceptual model and ontoUXON. ontoUXON is the HCI-ON fragment (reference conceptual model) transcribed into OWL (operational artifact).

At run-time, ontoUXON enabled the ETL process. As ontoUXON is an RDF graph/knowledge graph, it was used as the dataset (data model) in the UXON’s triplestore configuration. Consequently, ontoUXON was used to express queries (SPARQL) across it. To put in another way, all data and also metrics values are instantiated in ontoUXON and later stored in the triplestore, which is searched by SPARQL queries.
