Повышение эффективности извлечения информации из слабо структурированных источников на основе метаданных и базы знаний

Abstract

Proposed technology of increasing search effectiveness in not structured databases with Web-interface based on meta-data that shows database structure and data semantics. A model of meta-data for such databases and meta- data storage is proposed. Keeping meta-data and knowledge base on different servers allows to shorten request time. Results of experimental research on actual databases for different profiles of user operations were made. Experiments show that with real number of user requests to databases proposed technology has good response time and decreasing servers load. The more responses number grows, better proposed technology work.
