Revisit our use of reasoners #1328

Open jamesaoverton opened 3 years ago

jamesaoverton commented 3 years ago

OWL has a handful of "profiles" that specify subsets of the language. In OBO we tend to use the EL and DL profiles. The DL profile has most OWL features. The EL profile does not include negation, cardinality, or many of the logical characteristics of object properties. You can use Protege or robot validate-profile to figure out which profile your ontology uses.

Why use EL instead of DL? A DL reasoner has to do a lot more work than an EL reasoner, so EL can be much faster. To some extent, EL reasoners can also make better use of parallel processing. Although there are many OWL reasoners out there, in OBO we tend to use ELK for EL reasoning and HermiT for DL.

OBI has always used DL and has various axioms outside of the EL profile. But running HermiT on OBI takes 12 minutes on my laptop, while running ELK takes 4.6 seconds. I ran robot diff to compare the results, and found that only a few dozen axioms are different (see below). Specifically:

$ time java -jar build/robot.jar --prefix "REO: http://purl.obolibrary.org/obo/REO_" reason --input build/obi_merged.owl --reasoner ELK --output obi-elk.owl

real    0m4.620s
user    0m29.234s
sys     0m1.058s

$ time java -jar build/robot.jar --prefix "REO: http://purl.obolibrary.org/obo/REO_" reason --input build/obi_merged.owl --reasoner HermiT --output obi-hermit.owl

real    12m6.825s
user    12m47.018s
sys     0m4.947s

$ java -jar build/robot.jar diff --left obi-elk.owl --right obi-hermit.owl --labels true --output obi-elk.diff

Arguably, some of the inferences that HermiT makes but ELK doesn't should just be asserted. For instance, where ELK only sees subClassOf owl:Thing we could assert the parent that HermiT infers. We could also just assert some of the 'processed material' parents.

This was a surprise to me. When I'm working on OBI I often run HermiT (and wait and wait) to make sure that I'm seeing all the inferences. But it turns out that ELK is covering almost everything. So the lesson seems to be that we don't need to run HermiT as often to get good results, especially if we assert just a few more things that we are right now.

Thanks for raising this James. We have an interesting history here, in that we first assumed reasoners could fully 'understand' the logical term definitions if we made them complex enough. But then realized the limits of OWL, and adjusted our expectations downards. Moving from DL to EL would be another step 'down' in terms of reasoning. But I think we have realized that the use of common templates that structure how to write definitions for sets of terms is a lot more powerful. If I am not mistaken, there isn't a single assay term in your list of things missed by ELK. So if we aim to have templates for most (if not all) terms in OBI, I believe that we can switch to ELK, and have better results in terms of reasoning than we have now with a more complex reasoner.

In terms of how to do the switch: How about we keep both reasoners for releases, but switch to ELK for development?

Hope this is making sense.

Discussed on the OBI call 2021-04-12: I plan to go through this small number of axioms and see what we can either:

  1. simplify: if the axiom is just more complicated than it needs to be, we can simplify the axiom to remove negations and cardinality restrictions
  2. manually assert axioms that we definitely want

In the end, I propose that we use ELK most of the time, and periodically check to see if HermiT is inferring more than ELK is, then repeat those two steps above.

Help with this would be appreciated.

we can successfully assert the following inferences that HermiT makes:

As discussed on 2021-06-07: We have no plans to convert OBI to an EL ontology. But the axioms listed here are expensive and complex in some way, so it's worth reviewing them to see if they're really needed.

I had initially thought that we could just assert a few more axioms that would give ELK "hints" at what HermiT infers, but Hector has worked on this issue for a while, and now I'm less optimistic.
