Development of Geoinformation Technology for Monitoring Events on the Basis of Data from Unstructured Web Resource Text

Abstract

The article studies unstructured text from the informational web resources as a source of obtaining of geospatial data about current events in real time. Authors propose a scheme of construction of the geoinformation technology for monitoring events through the data of the unstructured web resource text, that will allow to collect and visualize geospatial and descriptive information about events on specific topics automatically and in real time. Key elements of the proposed methodology are geoparsing of unstructured text, geocoding of detected coordinates or addresses, and storing of results in the geodatabase. Proposed technology allows to create a web application for automatic identification and monitoring of events (objects) by parameters of their category, location and time. For the purposes of developing this system, authors proposed to use free software (except for ArcGIS Pro). This factor can be attributed to the advantages of the proposed technology.
