Increasing popularity of Semantic Web raises a question how we could make a simple user interface for building semantic queries while keeping high precision of results returned. This thesis presents a method that helps users to create SPARQL queries by allowing to dynamically add components to user interface. The goal of the work is to improve of user interface model for semantic queries by allowing users to construct and change it dynamically till obtaining the desirable answer results. That model was created on the base of analysis of Semantic Web languages, tools and existing portals, their functions and user interfaces. Algorithms for dynamic user interface generation based on user actions were developed that allow creating queries of various complexities with minimal amount of user interface components. Implementation and testing the prototype of the system using movie and wine ontologies has shown that dynamic construction and generation of query interface has desirable functionality and is easily applicable to various ontologies. Experimental comparison with existing semantic search portals has shown that the proposed dynamic user interface generation method could improve precision and recall of semantic queries and may be applied in semantic search portal applications. |
