    sem_apis.create_entailment performance

    amine.abdessemed

      Hello,

      We are inferencing semantic data using sem_apis.create_entailment function on 3 models (including OWL ontology) considering ‘RDFS’ and ‘OWLPRIME’ as rulebases.

      We have more than 16 million triples and the inferencing process is taking more than 2 days on a 8 GB ram, 8 cores server running oracle 11R2.

      We have noticed that more than 60% time is spent on these rules (that uses some distance notions I guess):

      rule: ITER_INC_CLOSURE

      rule: CLOSURE_ITER_INC_X_Y (X, Y numbers from 1 to 15)

      Please note that we are using these inf_components_in/options:

      'RDFS1-, RDFS2-, RDFS4A-, RDFS4B-, RDFS6-, RDFS8-, RDFS10-, RDFS13-, IFP-, CHAIN, UNION',

      'USER_RULES=T OPT_SAMEAS=T DOP=8 RAW8=T '

      Is there any other an option or way to speed up the process faster since we need to refresh our data every day?

      Thanks,

      Amine
