Introduction

I. Overview

Natural Language Processing (NLP) offers powerful solutions for crisis management by enabling real-time analysis of textual data from diverse sources such as social media, news, emergency calls, and public reports. Using NLP techniques like Named Entity Recognition (NER), sentiment analysis, and topic modeling, the system can:

• Detect emerging crises

• Categorize events

• Assess severity

• Filter misinformation

• Recommend effective resource allocation strategies

II. Problem Statement

Traditional crisis response systems face several challenges:

• Inability to handle large volumes of real-time, unstructured data

• Delayed or inefficient decision-making due to lack of automation

• Dependence on manual verification and centralized reporting

• Difficulty in combating misinformation

• Lack of a unified, AI-driven system for real-time insight and action

III. Literature Survey

Previous research shows significant advancements in NLP and AI for crisis detection and response:

• Yin et al. (2012): Early crisis detection via Twitter; 85% accuracy, but struggled with misinformation.

• Imran et al. (2013): Used NER for tweet classification; improved response, limited by labeled data needs.

• Burel & Alani (2018): Deep learning + NLP for Twitter event detection; 90% precision, high computational cost.

• Hasan et al. (2019): Sentiment analysis to assess distress levels; multilingual limitations.

• Li et al. (2020): Reinforcement learning for resource allocation; challenged by complexity.

• Sharma et al. (2021): BERT for NER in crisis tweets; 92% accuracy, but limited on rare events.

• Kumar et al. (2022): Time-series + NLP for improved prediction; required frequent updates.

• Wang et al. (2023): Hybrid AI (NLP + computer vision) for disaster response; efficient but resource-intensive.

IV. Tools and Technologies

• Language & Frameworks: Python, PyTorch, TensorFlow, FastAPI/Flask

• NLP Libraries: spaCy, NLTK

• Data Handling: Pandas, NumPy

• Communication & Queuing: Apache Kafka, RabbitMQ

• Testing & Management: Postman, JIRA/Trello

• Compatible OS: Windows XP to 10, Linux, Mac

V. Methodology

The system architecture includes:

1. Data Collection Layer: Aggregates data from social media, IoT sensors, emergency lines, and news.

2. NLP Processing Unit: Extracts entities, sentiments, and key topics from unstructured text.

3. Crisis Classification & Prioritization Module: Categorizes incidents and ranks them by urgency.

4. Resource Allocation System: Suggests and manages efficient distribution of aid.

5. Visualization Dashboard: Real-time insights for decision-makers.

The platform aims to automate crisis detection and response, ensuring faster and smarter decisions with minimal human intervention.

VI. Experiment Results (UI Features)

The system's front-end includes several interactive components:

• Home/Login Page: Secure access for users and admins.

• Admin Dashboard: Manage crises, user data, donations, and real-time reports.

• Crisis Profile Creation: Log events like fires, floods, and accidents with impact details.

• Donation Management: Track and visualize donations by type and condition.

• ChatBot Interface: Allocate resources via natural language commands.

• User/Donor Portal: Register, update profiles, and report emergencies.

• Active Crisis List: View real-time crisis data with urgency levels and user-uploaded evidence.
