In this article we explore the behavior of Twitter users under an emergency situation. [] Key Result This result shows that it is posible to detect rumors by using aggregate analysis on tweets.

The Impact of Posting URLs in Disaster-Related Tweets on Rumor Spreading Behavior

Posting URLs in disaster-related tweets increased rumor-spreading behavior even though the URLs lacked the hyperlink function, and some psychological factors that could explain this effect were identified.

Information Credibility on Twitter in Emergency Situation

A novel Twitter monitor model to monitoring Twitter online and an unsupervised learning algorithm is proposed to detect the emergency situation and a supervised method using learning Bayesian Network is used to predict the tweets credibility in emergency situation.

Epidemiological modeling of news and rumors on Twitter

This work uses epidemiological models to characterize information cascades in twitter resulting from both news and rumors, using the SEIZ enhanced epidemic model that explicitly recognizes skeptics to characterize eight events across the world and spanning a range of event types.

The Rule of Rumor Dissemination on tweets : How to Distinguish Rumors and News

The result shows that the social media network of the false rumor has some unique features, and the sentiment analysis results suggest that rumors are more easily questioned than the real news in thesocial media network.

How Did Rumors on Twitter Diffuse and Change in Expression? An Investigation of the Process of Spreading Rumors on Twitter during the 2011 Great East Japan Earthquake

This study investigated the data of 187 thousand tweets related to the Cosmo Oil rumor during the Great East Japan Earthquake of March 2011 and analyzed the change in Twitter expressions and the collective sense-making process during this catastrophe to suggest that collectivesense-making is rare in diffused tweets.

Identifying and characterizing user communities on Twitter during crisis events

A preliminary study to identify and characterize communities from a set of users who post messages on Twitter during crisis events, and shows that the top users represent the topics and opinions of all the users in the community with 81% accuracy on an average.

Why Did False Rumors Diffuse after the 2011 Earthquake off the Pacific Coast of Tohoku? Impact Analysis of the Network Structure

This paper analyzes how the diffusion of information on Twitter has been influenced by structural changes in the network that are caused by communication among users.

Information Abuse in Twitter and Online Social Networks: A Survey

This paper employs the usage of several algorithms as well as human intuition to track credibility of tweets and also the different ways the features of Twitter and other online social network are exploited to spread misinformation by certain users for their own benefits and profits.

Whom should I follow?: identifying relevant users during crises

This work proposes a novel approach to identify a subset of active users during a crisis who can be tracked for fast access to information by user identification along two dimensions: user's location and the user's affinity towards topics of discussion.

What Have We Missed When Examining Twitter as a Communication Medium During Disasters

A way to quantify message clarity in a tweet based on each tweet’s number of topics and the entropy measure is introduced, confirming that a decrease in message clarity lowers retweet frequency, and this relationship is moderated by supplemental information, such as Twitter URLs.



Twitter adoption and use in mass convergence and emergency events

The findings suggest that Twitter messages sent during these types of events contain more displays of information broadcasting and brokerage, and that general Twitter use seems to have evolved over time to offer more of an information-sharing purpose.

What is Twitter, a social network or a news media?

This work is the first quantitative study on the entire Twittersphere and information diffusion on it and finds a non-power-law follower distribution, a short effective diameter, and low reciprocity, which all mark a deviation from known characteristics of human social networks.

Applications of Topics Models to Analysis of Disaster-Related Twitter Data

This work explores the use of Topics models for analysis of disaster-related Twitter data, experimenting with Topics-based clustering and visualization, corpus selection, term weighting, as well as a new technique called dynamic corpus refinement.

Chatter on the red: what hazards threat reveals about the social life of microblogged information

This paper considers a subset of the computer-mediated communication (CMC) that took place during the flooding of the Red River Valley in the US and Canada in March and April 2009. Focusing on the

Microblogging during two natural hazards events: what twitter may contribute to situational awareness

Analysis of microblog posts generated during two recent, concurrent emergency events in North America via Twitter, a popular microblogging service, aims to inform next steps for extracting useful, relevant information during emergencies using information extraction (IE) techniques.

Citizen communications in crisis: anticipating a future of ICT-supported public participation

Drawing on disaster social science, a critical aspect of post-impact disaster response that does not yet receive much information science research attention is considered, with a focus on persistent citizen communications as one form of interaction in this arena.

"OMG, from here, I can see the flames!": a use case of mining location based social networks to acquire spatio-temporal data on forest fires

Improved the understanding on how LBSN can be used as a reliable source of spatio-temporal information is improved by analysing the temporal, spatial and social dynamics of Twitter activity during a major forest fire event in the South of France in July 2009.

OMG Earthquake! Can Twitter Improve Earthquake Response?

This exploratory study examines the tweets that followed the 30 March 2009 Morgan Hill earthquake and investigates the possibility of using the tweets to detect seismic events and produce rapid maps of the felt area.
