Semantic relatedness measures provide a means to determine how closely related two concepts may or may not be. In the area of ontology alignment, many lexical-based relatedness measures have been successfully applied within the realm of domain ontologies. The alignment initiative, however, has not included all measures of relatedness. More generic measures of relatedness, such as meronomy-based, have...
Extending the idea of computing with words in place of numbers to computing with words in a free, unstructured text, the paper presents the ontological semantics theory, methodology and technology for accessing, formally representing, and computing natural language to achieve a near-human understanding of it. It also demonstrates how ontological semantics handles various types of uncertainty, fuzziness,...
Ambient Intelligence offers significant benefits to e-commerce services, which is facilitated by the emergence of ubiquity (being available everywhere), universality (being able to operate in heterogeneous environments), uniqueness (relating services to a context such as the location) and working in unison (allowing multiple parties to work together). This type of e-commerce has been termed u-commerce...
The conceptual formalisms supported by typical ontologies may be not sufficient for handling imprecise information commonly found in many application domains. Fuzzy ontologies are developed to overcome this problem. The implementation, inference and query of fuzzy ontologies gain more attention in recent years. This paper addresses fuzzy ontology implementation and query answering on databases. We...
