The world of health is always changing.  To keep up, experts need a way to organize and understand all the new information.  This is where ontologies come in.  Think of them as big maps that show how different ideas in a field are connected.  They help experts see the big picture.  But these maps need to be updated regularly.  New ideas pop up all the time.  Some might have been overlooked at first.  Others are brand new, born from recent discoveries.

One way to update these maps is by using a large language model.  This is a type of AI that understands human language.  It can read lots of text and find new ideas that should be added to the map.  This process is called ontology enrichment.  It's like giving the map a makeover, adding new roads and landmarks.  It's a big job, so it's done automatically with the help of computers.

This method was recently tested in the field of Social Determinants of Health.  These are the conditions in which people are born, grow, work, live, and age, and the systems put in place to deal with illness.  The goal was to update an existing map, called SOHOv1, using information from PubMed, a big database of health studies.  The results were promising.  The map was successfully updated with new ideas.  This shows that the method could work in other fields too.

But here's a question to think about.  How good is the AI at understanding human language?  Could it miss some important ideas?  Also, who decides which ideas are important enough to be added to the map?  These are questions that need to be explored further.  The method is a step in the right direction, but it's not perfect.  It's a tool that can help experts, but it can't replace them.

The field of health is always evolving.  New ideas are always popping up.  To keep up, experts need tools that can help them organize and understand all this new information.  Ontology enrichment is one such tool.  It's a way to update the maps that experts use to navigate the world of health.  But it's not a magic solution.  It's a step in the right direction, but there's still work to be done.
