Discovering relations between indirectly connected biomedical concepts
2015
Journal of Biomedical Semantics
Preserved Fulltext
This work addresses this problem by using indirect knowledge connecting two concepts in a knowledge graph to discover hidden relations between them. ...
Furthermore, this work demonstrates that the constructed graph allows for the easy integration of heterogeneous information and discovery of indirect connections between biomedical concepts. ...
A trained model can in turn be used to discover a specific relation between indirectly connected concept pairs. ...
