An ontology is a structured semantic model, composed
of concepts, relations and instances. Data is a more
primitive but concrete assembly of instances described
by their attributes. An example of topic ontology
Open Directory of Web documents used in Google
organizing documents into topics and subtopics, such
“Science”, “Arts”, etc. However, many ontologies
originally manually developed without making
explicit connection to the data. We hereby introduce
concept of ontology grounding, where the concepts
relations from the ontology become associated with
data. This enables us both to explain concepts in more
concrete terms and to recognize them in the data.
