We've been doing some analysis looking at what users are looking for when they search TRIP. Below are two visual representations of this, using COPD as an example.
The top image shows all the additional search terms used when people have searched for COPD. In other words, if someone searched for 'COPD and exacerbations' we have analysed the auxiliary terms, in this example it's exacerbations. NOTE: Click on image to make bigger.
This second image uses a similar process to highlight the documents users actually went on to visit.
