I am not certain exactly what you are asking. Are you asking how to create an ontology that maps different names for the same concept together (eg. molecular weight -vs- compound weight) so that you can query across them?
If so the only examples I know of are BioFed: https://www.researchgate.net/publication/315120429_BioFed_Federated_query_processing_over_life_sciences_linked_open_data and Granatum: https://www.researchgate.net/publication/301952979_Linked_Biomedical_Dataspace_Lessons_Learned_Integrating_Data_for_Drug_Discovery Hope this helps Claude On Wed, Sep 25, 2019 at 1:04 PM elio hbeich <eliohbei...@gmail.com> wrote: > Dear All, > > I am searching to connect and map multiple ontologies. > Does anyone have any tool recommendations? > > Thank you in advance. > Best regards, > Elio HBEICH > -- I like: Like Like - The likeliest place on the web <http://like-like.xenei.com> LinkedIn: http://www.linkedin.com/in/claudewarren
