Abstract

Critical work tasks of any new domain installation are the creation of the domain knowledge graph and its population with relevant instance data. It is easier to implement and test an incremental approach. Most of the implementation effort is to conceptualize (in a knowledge graph) the structure of the new domain and to populate it with instances (data). In a proof-of-concept phase, the least-effort path is to leverage KBpedia or portions of it as is, make few changes to the knowledge graph, and populate and test local instance data. You may proceed to create the domain knowledge graph from pruning and additions to the base KBpedia structure, or from a more customized format. Some of our tasks in this area are to determine the domain and scope of the ontology; incorporate domain terminology; consider reusing existing ontologies; enumerate important terms in the ontology; define the types and the class hierarchy, especially into typologies; and define the attributes of the types. From the platform perspective, that means being able to select appropriate subsets from the knowledge base, process or transform them in some way, and then submit those result set to an external tool to conduct the designated work. Ongoing use and training demand that we adequately document all steps. If KBpedia is the starting basis for the modified domain ontology, and if incremental changes are tested for logic and consistency as they occur, then it should be possible to continue to evolve the domain knowledge graph coherently.
