Dr Emma Griffiths and Dr João Carriço join us to give us a crash course on ontologies, the bioinformatics secret sauce that makes all things work well. Microbial genomics data is like the Tower of Babel with public health talking to food regulators talking to agriculture talking to veterinarians talking to healthcare, all with different languages to describe similar things. So how do we get any work done at all? Listen in to why you need ontologies in your life!
