| Abstract [eng] |
Semantic network is the Internet network as a database, which contains an artificial intelligence character. One of the main idea of the Semantic Web seeks to make people interact with computers in natural language, when the user asks the computer is responsible. Service centers to transfer intellectual tasks to information systems to provide knowledge which could help to understand the content of the information entered. For this purpose, an ontology is used, which one of description language is RDF, for data retrieval and query presentation system uses SPARQL language. The user to ask questions system in natural Lithuanian language needed subsystem which transforms NLL to formal language and and create queries according to the rules. Also the subsystem transforms SPARQL results in the correct NLL sentence. The purpose of the work - to offer a tool that will allow to formulate semantic queries using NLL, to carry out them in the development of a prototype search system and give correct results. Objectives: 1. To analyze the transcription ontology languages and their development tools; 2. To analyze the SPARQL query language and query processing tools; 3. Set the Lithuanian language grammar rules affect the formulation of queries in natural Lithuanian language key aspects; 4. To design and implement a prototype system for ontology search, where queries are formulated in NLL 5. Identify the characteristics of the system established by experimental research. Research object - query formulation in natural Lithuanian language and the transformation to SPARQL queries. |
