Use of the Smart City Ontology for Relevant Information Retrieval

Today, many Intelligent Web Applications require the use of distributed knowledge bases formalized in the form of ontologies and thesauri. They are the new intellectual means for searching resources on the Internet, new methods for representing, systematizing and processing of knowledge and inquiries. They can accurately and effectively describe the data semantics for certain subject area and solve the problem of incompatibility and contradictory concepts. A brief overview of recent foreign investigations aimed at solving the problems of ontologies construction and development in various fields of science is carried out in this paper. Different points of view on the concepts of ontology used in modern information technologies are covered and the definition of this term is given in this paper. The ontological approach to the formation of information inquiries is considered, the search scheme on the basis of ontologies, the algorithm for the ontology domain construction and the example of ontology fragment construction in the "Smart City" data domain are presented.
