Resumen
Solar flares are phenomena capable of causing several damages in radio systems, communication
satellites, global positioning systems (GPS), among others. The possible damage can vary
according to the intensity of the explosion and these explosions are classified as A, B, C, M and
X. Predicting this phenomenon is not an easy task due the sparse data and the unknowledge
of relevante characteristics of the phenomenon. In this work we aim to improve the process of
prediction of solar flares building the knowledge about the domain of the solar cycle structured
in a domain ontology. The complexity of the data was abstracted by creating a domain Ontology
in order to improve the prediction process. To apply the ontology, it was decided to incorporate
it to the ECID solar explosion prediction method, which performs multi-class and multi-label
prediction with treatment for imbalanced data. In order to contribute to research on solar flares,
ECID was adapted to encompass the Onto Solar Flare ontology. The ontology was developed to
semantically enrich the ECID algorithm, the combination of the two tools generated the ECID
Onto. The results show a better distribution of classes, facilitating the final decision of the domain
specialist.
