Ontology Grounding
نویسندگان
چکیده
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 is Open Directory of Web documents used in Google organizing documents into topics and subtopics, such as “Science”, “Arts”, etc. However, many ontologies are originally manually developed without making an explicit connection to the data. We hereby introduce the concept of ontology grounding, where the concepts and relations from the ontology become associated with the data. This enables us both to explain concepts in more concrete terms and to recognize them in the data.

Grounding a Geographic Ontology on Geographic Data
Vagueness is prevalent within the geographical domain, yet it is handled poorly in existing ontology approaches. A proposed way to rectify this is to ground the ontology upon the data. By grounding the ontology, we make an explicit link between the ontology and the data, and thus allow reasoning to be made within the context of the particular data. In order to ground the ontology upon the data,...
متن کاملSemantic Grounding Strategies for Tagbased Recommender Systems
Recommender systems usually operate on similarities between recommended items or users. Tag based recommender systems utilize similarities on tags. The tags are however mostly free user entered phrases. Therefore, similarities computed without their semantic groundings might lead to less relevant recommendations. In this paper, we study a semantic grounding used for tag similarity calculus. We ...
متن کاملGrounding Geographic Information
Ontologies need to introduce some primitive symbols used for the definition of more complex ones. These primitive symbols have no formal definitions in the ontology, and as ontologies usually are incomplete axiomatizations, the semantics of the primitives remain ambiguous (Guarino 1998). This shifts the problem of semantic interoperability to the problem of how to ground such primitives. Ground...

Haktan Akcin (Lingnan University): “Naturalized metaphysics, modal structuralism, and grounding” I try to clarify the structuralist claim that the world has an objective modal structure with reference to the recent grounding discussions. Against criticisms that the ontological priority relations in OSR are vague, I highlight the scale-relative ontology suggested by Ladyman & Ross. Since structu...
متن کاملGrounding Semantic Web Services with Rules
Semantic web services achieve effects in the world through web services, so the connection to those services—the grounding—is of paramount importance. The established technique is to use XML-based translations between ontologies and the SOAP message formats of the services, but these mappings cannot address the growing number of non-SOAP services, and step outside the ontological world to descr...
