1. Introduction

Natural disasters are associated to chaotic situations in which information is usually incomplete and imprecise, and this lack of information makes difficult the process of making decisions and managing effectively catastrophes. • Public awareness is an essential element of preparedness for saving lives and livelihoods. •Individuals and communities play important roles in managing risks from natural hazards.

What is ? • A complete platform for managing information about disasters based on user-generated data. • Hosted on GoogleCode (GPL) mobile Intelligent web mashups techniques

2. Architecture

Architecture

SERVER DISASTERS2.0 REST architecture: Restlets

REST API… PUT: /5/latitud/1.5 GET: /events GET: /people GET: /resources GET: /events/fire GET: /resources/ambulance GET: /events/fire/year/2008 GET: /events/date/15-01-09+13:30:31 DELETE: /4 POST: /type=fire&latitud=…

… JSON RESPONSE [ { quot;idquot;:1, quot;itemquot;:quot;eventquot;, quot;type“:quot;firequot;, GET: /events quot;namequot;:quot;Fire in the Parkquot;, quot;descriptionquot;:quot;Some description herequot;, quot;infoquot;:quot;Some info herequot;, quot;latitudquot;:40.390679, quot;longitudquot;:-3.692541, quot;addressquot;:“Somewhere Streetquot;, quot;statequot;:quot;activequot;, quot;sizequot;:quot;bigquot;, quot;trafficquot;:quot;mediumquot;, quot;datequot;:quot;2007-01-01 00:00:01.0quot;, quot;modifiedquot;:quot;2008-04-15 13:07:00.509quot;, quot;user_namequot;:quot;anonymousquot;, quot;user_typequot;:quot;citizenquot; }, { quot;idquot;:4, … } ]

3. Web Client

Web Client

Ajax Engine Google Maps API

4. Mobile Client

Mobile Client

Mobile Client • Developed with Mojax Framework for Mobile Ajax  Creates J2ME applications  using web technologies (HTML, CSS, JavaScript) Mojax • Synchronized with the platform • Compatible in any terminal with Java • Only data transmission (no presentation) • Works with/without connectivity

5. Intelligent Techniques

Intelligent Techniques

Expert System based on Rules Developed with Jess (Sandia National Labs)  Resource planification and assignation in real time  Resources are assigned and freed based on rules  wich take into account: disaster severity  3 number and severity of casualties  1 associated traffic  2 possibility of increasing… 

Expert System based on Rules

Multiagent Platform • Developed with Jadex: BDI Reasoning Engine (Belief-Desire-Intention) • Four different agents for two different architectures (centralized vs descentralized) FIRE ENGINE POLICE CAR COORDINATOR AMBULANCE • Purpose: simulation (now) and more (to come) such as making-decission support, coordination…

5. Conclusions

Conclusions Disasters2.0 has been shown as a web2.0 based platform which  enables sharing and managing disasters information generated by users. The platform provides a REST API which enables any client to  interact with it. As an example, a web client and a mobile client have been developed. Intelligent techniques can also leverage the REST API to interact  with the platform such as the Expert System or the Multiagent Platform developed.
