Database of emergency telephone calls - system tools for real-time registration and metadata searching

This paper reports results of experiments carried out in relation with the research devoted to creation and maintenance of a database of telephone calls to emergency services. This database is comprised of concise but unambiguous information about all contained emergency calls and of tools for efficient data searching. We present the tools for real-time data registration, off-line metadata preparation, and searching of particular telephone calls. The environment setup, the database architecture, and proper equipment are also described.
