This article describes some tools to improve the foresight process and help the watchers to identify interesting information, in order to detect early warnings on threats or opportunities in open sources. A formal model of scenario is proposed to represent the expert knowledge about the potential situations in the environment and their links. The ontology Scenari Onto allows the scenario exploitation to collect interesting documents on the Web and presents them to the watchers for a manual analysis. A Graphic User Interface (GUI) component has been developed to build scenarios graphically. To exploit the capitalized knowledge, Web Lab services have been developed. Finally, an experimentation has been set up to evaluate the system, showing encouraging results. |
