Subject: classifying semantic relations

 

My name is Rick Biehl, and I am a healthcare data warehouse architect
serving several medium-to-large US-based hospitals.  As I've done this work
for some seven years now, I continually monitor the ontology community to
try to take advantage of some of the very interesting work I see going on
around me.  Today, I commonly take advantage of several ontological
frameworks in my warehousing work.  I've got a set of ontologies that I load
from UMLS, and I'm now looking for a more effective way to interpret and use
that data in some of my warehouse queries.

 

Recognizing that I might be asking these questions in the wrong terms, I'm
looking for one or more resources that I can use to better understand
exactly what I'm asking about, and what capabilities might exist across the
community to help me solve my problem. Assuming something about what I'm
trying to do is novel, I'm also interested in better understanding how what
I'm doing can contribute back to the community.

 

My situation is that my data includes many cross-ontology mappings in the
form of exactMatch, closeMatch, narrowMatch, broadMatch, and relatedMatch.
I generally query my data by taking a search term, expanding the exactMatch
set, building the broader closeMatch neighborhood, and then scaling down the
narrowMatch trees.  I currently (in a fairly hard-coded fashion) include the
inverses of isA and partOf among my narrowMatch criteria.  (I'm using
recursively coded SQL statements against Oracle relational tables.)  Which
leads me to my current question....

 

Are there any current sources, or plans in the works such as the Relations
Ontology, that will allow me to know how other semantic relations that I
have in my warehouse can also be included in my search expansions?   I know
that the hasFormulation relation in my drug ontology is a narrowMatch, but I
only know that because I know that.  I know that the isDosageForm is a
broadMatch for the same reason.  I want those relations in my queries, but I
don't know how to get them there without hard-coding them; and that wouldn't
be sustainable.  Are there such resources, or could I be looking at using my
own local extensions of a relation-oriented ontology to drive my logic?

 

Can anyone point me in the right direction? Thanks, - Rick
