[bioontology-support] [BioPortal] Feedback from Melissa Haendel

Hi John,

Nice to see you in my inbox.

We are seeing a lot of variability in the rankings. Also there are some outdated or never-used ontologies on the list higher than some we know are more widely used. Is it simply because of people landing there from Google? 

This is an interesting question- how to monitor usage. I wonder what a longer period might look like, and/or by ontologies for which someone actually opens the graph or downloads the file? 

For openly available ontologies, its a nice metric for popularity that we can use in our grants, but not if the ranking changes frequently and by a lot. 

Anyway, there may well be nothing wrong, its just less useful for this purpose then?

Let me know if you want to brainstorm.

>> popularity ranking doesn't seem correct and seems to change daily. I think how it was earlier seemed to work better. A user usually wants to know how frequently a source is accessed, maybe do so over the past year or quarter, so that they don't jump around so much?
