(Metric Impl) Ontology is a member of the OBO Foundry #20
Comments
@muhammadaliqasmi I discussed this metric with @nfriesen and will give you a more detailed guide for its implementation below. Please stop reading at the horizontal line. @jerdeb below that line there are some further questions that still need clarification (by you looking into the literature or even talking to the use case partners). This metric is actually very similar to UndefinedClassesOrProperties. We need to compute the ratio of resources referenced in our dataset that are defined in ontologies that are members of the OBO Foundry. @jerdeb's comment above that “we need to check only for the the type of an instance” (i.e. for the objects of triples whose predicate is Therefore, @muhammadaliqasmi, I think we can do the following:
From this we know that
E.g., for http://purl.obolibrary.org/obo/OBI_9991118, this is the case. @jerdeb open questions start here: Should this metric return "true or false", or a ratio (i.e. how of the classes/properties (also individuals?) used in a dataset are from ontologies in the OBO Foundry). "ratio" makes more sense IMHO, as the question with "true or false" is when we should return true: if all classes/properties/individuals that our dataset reuses are from OBO Foundry ontologies, or if some of them are? Secondly, is the above “OBO Foundry membership check” actually right? Dereferencing http://purl.obolibrary.org/obo/OBI_9991118 takes me to http://www.ontobee.org/browser/rdf.php?o=OBI&iri=http://purl.obolibrary.org/obo/OBI_9991118 (and it also gives some meaningful RDF/XML to a linked data client). So I think our job is to see whether the stuff we can download by dereferencing that URI has a certain structure that looks like “OBO Foundry”. I don't know whether this mechanism

This metric detects non reputable resources by retrieving URI of resources from data sets and prefix match with "http://purl.obolibrary.org/obo/". Metric value = (total number of NOT reputable resources ) / ( total number of resources ) Metric Value Range : [0 - 1] , Best Case : 0, Worst Case : 1 (for further changes/improvements, kindly re-open this issue). . |
This is a Reputation Dimension.
In this metric we need to check if the used ontologies (therefore we need to check only for the type of an instance) are part of the OBO Foundry

In the class comment, mention that this metric is specific to the EBI use-case
