COSAS
A Digital transformation tool for first responder organisations to support effective monitoring of social media information that is related to a disaster event.
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.
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 is a suite that offers:
- Crisis event-related tweets dashboard
- Multimodal disambiguation for irrelevant tweet removal
- Cluster view and event monitoring
- Geo-localization in text
