Interfax develops new search engine for SCAN system
"The upgraded SCAN is above all a system of ready-made templates for scanning and presenting information. To make the radical changes to the system possible, we have completely overhauled the way SCAN works and switched the system to an object-oriented model. As a result, searches are more accurate, and opportunities have been provided to handle geographical objects, facts and themes, the tonality of publications, direct and indirect speech, and authors," said Interfax Deputy General Director and SCAN Project Manager Roman Laba.
The object-oriented search engine in SCAN, based on the use of instruments of linguistic and statistical analysis, produces no ‘Information noise." The system also prompts options for advanced searches.
Another addition is a mechanism for finding positive and negative mentions in works in SCAN, not only in relation to publications as a whole, but to each object in particular. In addition, citation frequency ratings for persons, companies and other objects are available in ready-made form.
*** The SCAN (System for Comprehensive Analysis of News) search-and-analysis system provides access to the electronic resources of Russian media organizations. The system was designed by Interfax and uses hi-tech tools to search, monitor, and analyze textual information.
The system is unique in that it is the only resource which carries archives of Interfax reports since 1989. In addition to this, the system‘s integration with other Interfax information systems provides a unique set of instruments to compare data and to make deeper analysis The instruments of processing information provided helps group data and to track down individual documents to get reference information, to gather market information, to find information about persons, companies and regions, and to collect statistics and draw up reference frequency ratings.
SCAN sources information from suppliers on exclusively legal terms. The system currently provides full-text versions of the main central and regional media (about 5,000 sources), with daily additions of more than 30,000 documents.
