Hello All,

Need some help to tune this piece of code. Let me describe the use case

A user would upload a very complex ontology into  a webpage and selects a 
reasoner from a  drop down list which he/she wants to apply for a “Business 
Function” .

Example of complex ontology

https://s3-ap-southeast-2.amazonaws.com/kamalraj-share/SNOMED_module4fma.owl

https://s3-ap-southeast-2.amazonaws.com/kamalraj-share/SNOMED_module4nci.owl

When the user selects OWL_MEM as ontology specification, this piece of code 
just flies and no issues at all (I presume no reasoning or inferencing is 
applied here)

When the user selects OWL_MEM_MICRO_RULE_INF , the system hangs in this piece 
of code.

OntClass ontClass = ontModel.getOntClass(“Some URI");

Sample Code
File file = new File("/Users/kamalrajjairam/Downloads/SNOMED_module4fma.owl");
InputStream inputStream = new FileInputStream(file);

        Model m = ModelFactory.createDefaultModel();

        m.read(inputStream, null);

       OntModel ontModel = 
ModelFactory.createOntologyModel(OntModelSpec.OWL_MEM_MICRO_RULE_INF, m);

       OntClass ontClass = ontModel.getOntClass(variable);

        Questions
How do i tune this piece of code? Should i be listing statements instead of 
using APIs in OWLClass?

Thanks
Kamalraj
