An Ontology Design Pattern to Define Explanations
The document discusses the need for a formal definition of 'explanation' in various fields, including philosophy, neuroscience, linguistics, psychology, and computer science, to enhance understanding of data patterns. It presents an ontology design pattern (ODP) that structures the explanation process by illustrating the relationship between events, circumstances, and outcomes. The authors aim to refine this ODP and explore its applications, particularly in the Dedalo project for automatic data analysis and explanation.

Editor's Notes
- #3 even tho
- #4 but if we explain it using linked data background knowledge the explanation process is faster
- #5 ...in our case we had popular searches over the Web... we were interested at knowing why something becomes more popular at a given time it can be interesting especially when this happens regularly ✚★✚✪
