Load the model which contains instance data to be used in Semantic Search.

Parameters:

root - File location of the application data (e.g. "D:/NECTEC/SKAF_HOME/AppData/Employee").

combineData - If it is true, all the data from specified paths will be collected into the memory instead of getting only from specified root.

Returns:

- Ontology model for Semantic Search.

loadModelForRecommender

public static com.hp.hpl.jena.ontology.OntModel loadModelForRecommender(String root,
                                                                        boolean combineData)

Load the model which contains instance data to be used in recommender queries.

Parameters:

root - Root of the application data (e.g. "D:/NECTEC/SKAF_HOME/AppData/Employee").

combineData - If it is true, all the data from specified paths will be collected into the memory instead of getting only from specified root.

Returns:

Ontology model for recommender.
