This location analysis is based only on tweets which have location metadata (~10% of total volume). Be sure to select both time and region of interest to see spatio-temporal-thematic social signals.

The following list shows top 100 influential Twitter users while talking about a topic, which can be multi-faceted - thematic,person,organization etc. The following network shows the connectivity among these influential Twitter users about a topic chosen on left menu. Colors denote the user level characteristics such as sentiment polarity for the topic, political affiliation, profession etc. Here, we specifically decided to show the characteristics and connectivity of top users, because they have potential to drive the community for desired actions. (Please check our Insights tab for such examples) Wondering about Science behind it? Check here.

==Description: May 23, 2013==
The following networks shows interations among the influential users talking about specific needs during the Oklahoma-Tornado response. They can used to channelize important situational awareness messages effectively in the entire network of Twitter. We do note that they are interacting less with each other, it will be more effective coordination of resources and information neeeds if interactivity is higher.
The list on the left frame shows such influential users who can be clicked to reach their Twitter profiles. Responders can engage with them for finding specific information, for example, verifying situation, contacting them to spread drop-off locations, contacting them to organize volunteer drives, etc.

Oklahoma disaster monitoring and coordination

- Check the video of how Twitris was monitoring Twitter for identifying information nuggets in real-time for helping public and responders find quick summary of what was going on. - Snapshot of various informative nuggets trending on the next day morning.
- Quick description of the purpose of each widget: (The pipeline of automatic analyses runs every hour)
* The Popular Topics widget shows trending topical tags extracted from the massive tweets, to give quick summary of what is trending.
* The Browse by Location widget shows trending topical tags extracted on the map with spatial and temporal dimensions, to give quick summary of what is trending at a location at certain point of time.
* The Network Analysis widget shows top influential users corresponding to topical discussion communities on Twitter. For example, who are the most influential people while discussing about volunteer assistance. It provides a way to engage with the target audience.
* The Real-time widget shows the incoming Twitter stream in real-time on the map, while also show color for what is the type of the tweet, for example, Green color to refer to money donations related data.
* The Insights widget shows helpful snapshots of the analysis that add value to viewer's understanding of the event processing.

- Resources for: How and Where to help
- Resources for: Who were offering to help and How


- Examples of offers we automatically identified and provided to our colleagues at various responder organizations, including Red Cross, FEMA and SparkRelief:
Does anyone know where to send a check to donate to the tornado victims?
I want to go to Oklahoma this weekend & do what i can to help those people with food,cloths & supplies,im in the feel of wanting to help ! :)
Anyone know how I can make a donation via text to the Red Cross for Oklahoma?
Where do I go to help out for volunteer work around Moore? Anyone know?

- Examples of requests we automatically identified:
Thanks to USA Today for posting ways to help those in Oklahoma. Here is the article if you would like to do your... http://t.co/DxJee9S8i7
How You Can Help Victims of the Tornado in Oklahoma\See more: http://t.co/wCVjjKnhQR http://t.co/ZEEiAA5yzB
Text REDCROSS to 909-99 to donate to those impacted by the Moore tornado! http://t.co/oQMljkicPs
Please donate to Oklahoma disaster relief efforts.: http://t.co/crRvLAaHtk


- We observe that several of these offers and requests identified can be matched also, our on-going research study under review addresses the problem of automatically matching these resource requests and offers. We are making an international collaborative effort in the space of Crisis Informatics with our colleagues at QCRI, Patrick Meier and Carlos Castillo.








What is Twitris+?

A Semantic Social Web application with real-time monitoring and multi-faceted analysis of social signals to provide insights and a framework for situational awareness, in-depth event analysis and coordination, emergency response aid, reputation management etc.

Why Twitris+?

Users are sharing voluminous social data (800M+ active Facebook users, 1B+ tweets/week) through social networking platforms accessible by Web and increasingly via mobile devices. This gives unprecedented opportunity to decision makers-- from corporate analysts to coordinators during emergencies, to answer questions or take actions related to a broad variety of activities and situations: who should they really engage with, how to prioritize posts for actions in the voluminous data stream, what are the needs and who are the resource providers in emergency event, how is corporate brand performing, and does the customer support adequately serve the needs while managing corporate reputation etc. We demonstrate these capabilities using Twitris+.

Key Features

  1. Decision making analytics platform for multi-faceted analyses of social data: spatio-temporal-thematic, people-content-network, sentiment-emotion-subjectivity etc.
  2. Answering questions of interests to corporate analysts and event coordinators
  3. Extraction of insights from social signals: Aggregation and filtering of social data, web resources (news, Wikipedia pages, multimedia), SMS data, followed by applying background knowledge to perform multi-faced analyses.
  4. Applications beyond state-of-the-art research in social-computing, such as in Health 2.0, cyber-physical systems etc.
