Abstract
Augmenting formal medical knowledge is neither manually nor automatically straightforward. However, this process can benefit from rich information
in narrative texts, such as scientific publications. Snomed-supervised relation extraction has been proposed as an approach for mining knowledge from texts in
an unsupervised way. It can catch not only superclass/subclass relations but also
existential restrictions; hence produce more precise concept definitions. Based on
this approach, the present work aims to develop a system that takes biomedical
texts as input and outputs the corresponding EL++ concept definitions. Several
extra features are introduced in the system, such as generating general class inclusions (GCIs) and negative concept names. Moreover, the system allows users to
trace textual causes for a generated definition, and also give feedback (i.e. correction of the definition) to the system to retrain its inner model, a mechanism for
ameliorating the system via interaction with domain experts
