During crises and disasters, social media gets flooded with information in the form of text and images, which can be leveraged to manage the situation.
FREMONT, CA: Researchers and practitioners have focused on creating resources and technologies in the broad domains of applied artificial intelligence by utilizing multi-modal information sources (AI). People utilize social media extensively to communicate after natural catastrophes, posting multimedia information in texts and photographs. It is essential to use all available information sources in such dire circumstances to better gather crucial information on the issue.
Social media has established itself as a quick and essential channel for information exchange and communication during a disaster due to the growing use and widespread accessibility of cell phones and the internet. Social media is a crucial tool for disaster relief and emergency response because of how quickly information is spread there.
For instance, 12 minutes before they surfaced in the conventional media, the first news of the 2011 Utoya assaults in Norway came on social media. Effective catastrophe management requires categorizing such reports into relevant and actionable categories. Organizations like The United Nations Office for the Coordination of Humanitarian Affairs (OCHA), whose main goal is to gain situational awareness and actionable information to save lives, lessen the suffering of affected people, and rebuild communities, are in great need of this refined information.
Machine learning and natural language processing communities have used the data generated on social media during disasters to analyze, categorize, and summarize crisis-related material.
The amount of multimedia content on various social media networks has increased dramatically with the accelerated development in internet speed. Social media information frequently uses text and images to communicate the point. A partial understanding of the content can result from ignoring either modality. The spread of rumors or misleading information during a disaster is another crucial factor that could have detrimental effects. The legitimacy of textual information increases when an image is added; therefore, combining all the modalities may yield useful evidence for better decision-making. This is even more crucial in emergencies when it is essential to employ every available resource to get more exact information since people's lives are on the line.
