The aim of the work is to analyze the means of semantic search in Wiki resources and to develop directions for expanding its capabilities through the use of modern tools of knowledge management. The article analyzes the benefits that the use of semantic markup of the Web information resources provides for users by more convenient and quick access to content. The techniques of application of ontological analysis for search and navigation in semantized Wiki resources are considered. The definition of Wiki ontology that formalizes the information about the structure of the knowledge base of information resource (both ordinary and semantized) based on Wiki technology is proposed. The theoretical foundations of determining the measure of semantic similarity between domain concepts based on ontologies and taxonomies are analyzed. Methods of design of navigation tools oriented on Wiki resources are proposed. These methods are based on retrieval of pages that use semantically related concepts. The implementation of the proposed approach in the online version of the Great Ukrainian Encyclopedia (e-VUE) is described. Such approach supports an extension of the functionality of the encyclopedic resource by providing means of access to content on a semantic level. The methodological principles of the organization of the e-VUE knowledge base and the categorization of its articles that ensure the use of semantic proximity estimations between domain concepts for discovery of such concepts are substanti­ated. Problems in programming 2019; 4: 11-27
