| Abstract [eng] |
The purpose of the ontology study, supplemented with an individual recognition accuracy parameter, is to enable the users of semantic search to see the accuracy estimates of identified individuals and to select, sort and query the results based on them. The impact of the ontology supplementation on the accuracy parameter will be assessed by the search speeds. For this purpose, an experimental system has been developed, several ontology variants have been prepared that include individuals with and without accuracy estimates, and SPRQL requests of varying complexity. The semantic graph database, GraphDB, is used to store ontologies. The experimental system allows you to create queries of varying complexity, perform semantic search, view search results and query execution speed data. The experiment found that the decision to provide search engine users with accuracy estimates of the queries generated by the query has a clear impact on query execution speeds. The impact on speeds depends on the complexity of the query, the size of the structure of the result, the amount of output and the size of the ontology itself. |
