Problem Definition
Exposure of citizens to potential disasters has led to vulnerable societies that require risk reduction technologies and solutions for monitoring crisis events and environmental issues. Social media streams often include crucial information and multimodal descriptions of an event (e.g. people in danger) from multiple views. This information is “hidden” among hundreds of other irrelevant posts with metaphoric use of key terms or in other locations.
What we offer
COSAS is a Social Media Sensing and Monitoring tool for first responder and civil protection organizations to support effective monitoring of social media information that is related to a disaster event. The tool utilizes social media streams, which often include crucial information and multimodal descriptions of an event (e.g. people in danger) from multiple views, in order to reveal all the “hidden” insights that may derive from them.
The social media monitoring tool involves the crawling, representation, and analysis of Twitter content, aiming to classify tweets as relevant or irrelevant to each use case scenario for multiple languages. Relevance classification analysis aims to deliver to the end user information that is potentially useful for decision makers, emergency managers and operators, through effective visualizations. The social media information is filtered through a text analysis solution to extract concepts and locations from text for further integration, visualization and decision making.
COSAS provides the following functionalities:
- Crisis event-related tweets dashboard
- Multimodal disambiguation for irrelevant tweet removal
- Cluster view and event monitoring
- Geo-localization in text
- GIS visualization
- Notification system
- Command and Control room extension
Impact
The use of COSAS can potentially produce a positive impact in 2 different areas of the UN’s Sustainable Development Goals which can be translated to positive ESG metrics for the companies that use our solution.
