A Survey Of Recommender Systems In Twitter, Su Mon Kywe, Ee Peng Lim, Feida Zhu

Research Collection School Of Computing and Information Systems

Twitter is a social information network where short messages or tweets are shared among a large number of users through a very simple messaging mechanism. With a population of more than 100M users generating more than 300M tweets each day, Twitter users can be easily overwhelmed by the massive amount of information available and the huge number of people they can interact with. To overcome the above information overload problem, recommender systems can be introduced to help users make the appropriate selection. Researchers have began to study recommendation problems in Twitter but their works usually address individual recommendation tasks. There …

On Recommending Hashtags In Twitter Networks, Su Mon Kywe, Tuan-Anh Hoang, Ee Peng Lim, Feida Zhu

Research Collection School Of Computing and Information Systems

Twitter network is currently overwhelmed by massive amount of tweets generated by its users. To effectively organize and search tweets, users have to depend on appropriate hashtags inserted into tweets. We begin our research on hashtags by first analyzing a Twitter dataset generated by more than 150,000 Singapore users over a three-month period. Among several interesting findings about hashtag usage by this user community, we have found a consistent and significant use of new hashtags on a daily basis. This suggests that most hashtags have very short life span. We further propose a novel hashtag recommendation method based on collaborative …

Community-Based Classification Of Noun Phrases In Twitter, Freddy Chong Tat Chua, William W. Cohen, Justin Betterridge, Ee-Peng Lim

Research Collection School Of Computing and Information Systems

Many event monitoring systems rely on counting known keywords in streaming text data to detect sudden spikes in frequency. But the dynamic and conversational nature of Twitter makes it hard to select known keywords for monitoring. Here we consider a method of automatically finding noun phrases (NPs) as keywords for event monitoring in Twitter. Finding NPs has two aspects, identifying the boundaries for the subsequence of words which represent the NP, and classifying the NP to a specific broad category such as politics, sports, etc. To classify an NP, we define the feature vector for the NP using not just …

User Taglines: Alternative Presentations Of Expertise And Interest In Social Media, Hemant Purohit, Alex Dow, Omar Alonso, Lei Duan, Kevin Haas

Kno.e.sis Publications

Web applications are increasingly showing recommended users from social media along with some descriptions, an attempt to show relevancy - why they are being shown. For example, Twitter search for a topical keyword shows expert twitterers on the side for 'whom to follow'. Google+ and Facebook also recommend users to follow or add to friend circle. Popular Internet newspaper- The Huffington Post shows Twitter influencers/ experts on the side of an article for authoritative relevant tweets. The state of the art shows user profile bios as summary for Twitter experts, but it has issues with length constraint imposed by user …

Colleges’ And Universities’ Use Of Twitter: A Content Analysis, Darren Linvill, Sara E. Mcgee, Laura K. Hicks

Publications

This study explored how colleges and universities are employing Twitter, a popular micro-blogging tool. Using Kent and Taylor's principles of dialogic communication, a content analysis was performed on individual tweets (n = 1130) from 113 colleges and universities. Tweets were coded for whether or not they met each principle of dialogical communication and why. It was found that institutions are not employing Twitter in a dialogic way and they are, instead, employing it primarily as an institutional news feed to a general audience. The implications of this finding are discussed.

The Mouse Who Ruled His Kingdom: An Agenda Setting Analysis Of The Walt Disney World Company, Jacob Overbey

Masters Theses

People are seeking their news in more social environments, but very little research has been conducted on agenda setting and online environments. This thesis examined the agenda setting relationship between an organization on Twitter, @WaltDisneyWorld (i.e., The Walt Disney World) and public opinion on Twitter. The relationship was examined using Twitter's database of tweets to measure public opinion on Twitter. Since the news media is losing steam on the ability to break news, and social media is growing rapidly, this study tested the value of the agenda setting theory on social media. To this end, this thesis qualitatively examined the …

Observatory Of Trends In Software Related Microblogs, Achananuparp Palakorn, Nelman Lubis Ibrahim, Yuan Tian, David Lo, Ee Peng Lim

Research Collection School Of Computing and Information Systems

Microblogging has recently become a popular means to disseminate information among millions of people. Interestingly, software developers also use microblog to communicate with one another. Different from traditional media, microblog users tend to focus on recency and informality of content. Many tweet contents are relatively more personal and Opinionated, compared to that of traditional news report. Thus, by analyzing microblogs, one could get the up-to-date information about what people are interested in or feel toward a particular topic. In this paper, we describe our microblog observatory that aggregates more than 70,000 Twitter feeds, captures software-related tweets, and computes trends from …

When Antitrust Met Facebook, Christopher S. Yoo

All Faculty Scholarship

Social networks are among the hottest phenomena on the Internet. Facebook eclipsed Google as the most visited website in both 2010 and 2011. Moreover, according to Nielsen estimates, as of the end of 2011 the average American spent nearly seven hours per month on Facebook, which is more time than they spent on Google, Yahoo!, YouTube, Microsoft, and Wikipedia combined. LinkedIn’s May 19, 2011 initial public offering (“IPO”) surpassed expectations, placing the value of the company at nearly $9 billion, and approximately a year later, its stock price had risen another 20 percent. Facebook followed suit a year later with …

Tracking Tweets: Engage In Conversation About Your Library On Twitter, Katy Kelly

Roesch Library Faculty Presentations

Get an uncensored look at what people are saying about your library and provide responsive service using Twitter. For two years, tweets about and to a library Twitter account have been responded to, saved, and analyzed, revealing attitudes towards the library that were previously unknown. Once the library Twitter account began responding to tweets, the tweets about the library increased as did the number of the account followers (up 500%). By the third semester of an active and responsive Twitter presence, a student journalist named the library Twitter account a "campus legend." This poster session will showcase Twitter as a …

Prediction Of Topic Volume On Twitter, Yiye Ruan, Hemant Purohit, David Fuhry, Srinivasan Parthasarathy, Amit P. Sheth

Kno.e.sis Publications

We discuss an approach for predicting microscopic (individual) and macroscopic (collective) user behavioral patterns with respect to specific trending topics on Twitter. Going beyond previous efforts that have analyzed driving factors in whether and when a user will publish topic-relevant tweets, here we seek to predict the strength of content generation which allows more accurate understanding of Twitter users' behavior and more effective utilization of the online social network for diffusing information. Unlike traditional approaches, we consider multiple dimensions into one regression-based prediction framework covering network structure, user interaction, content characteristics and past activity. Experimental results on three large Twitter …

Visualizing Media Bias Through Twitter, Jisun An, Meeyoung Cha, Gummadi, Krishna, Jon Crowcroft, Daniele Queria

Research Collection School Of Computing and Information Systems

Traditional media outlets are known to report political news in a biased way, potentially affecting the political beliefs of the audience and even altering their voting behaviors. Therefore, tracking bias in everyday news and building a platform where people can receive balanced news information is important. We propose a model that maps the news media sources along a dimensional dichotomous political spectrum using the co-subscriptions relationships inferred by Twitter links. By analyzing 7 million follow links, we show that the political dichotomy naturally arises on Twitter when we only consider direct media subscription. Furthermore, we demonstrate a real-time Twitter-based application …

The Growing Use Of Social Media In Political Campaigns: How To Use Facebook, Twitter And Youtube To Create An Effective Social Media Campaign, Kaitlin Vonderschmitt

Mahurin Honors College Capstone Experience/Thesis Projects

A political campaign is carefully crafted for each candidate, to address their constituency and present the candidate and party in the best possible way. After the creation of the United States suffrage was limited to land owning white men, these men were involved in politics by reading local newspapers and visiting the politicians face to face. However as we fast forward to the 1930’s President Franklin D. Roosevelt used the radio to connect with the American public, and then in 1960’s Nixon and Kennedy’s debate introduced the mass-produced version of face-to-face politics through televisions all over the country we begin …

#Epicplay: Crowd-Sourcing Sports Video Highlights, Anthony Tang, Sebastian Boring

Research Collection School Of Computing and Information Systems

During a live sports event, many sports fans use social media as a part of their viewing experience, reporting on their thoughts on the event as it unfolds. In this work, we use this information stream to semantically annotate live broadcast sports games, using these annotations to select video highlights from the game. We demonstrate that this approach can be used to select highlights specific for fans of each team, and that these clips reflect the emotions of a fan during a game. Further, we describe how these clips differ from those seen on nightly sportscasts.

‘America’S “Engagement” Delusion: Critiquing A Public Diplomacy Consensus’, Hamilton Bean, Edward Comor

FIMS Publications

The Obama administration has embraced ‘engagement’ as the dominant concept informing US public diplomacy. Despite its emphasis on facilitating dialogue with and among Muslims overseas, this article demonstrates that, in practice, engagement aims to leverage social media and related technologies to persuade skeptical audiences to empathize with American policies. Indeed, its primary means of implementation – participatory interactions with foreign publics – is inherently duplicitous. Through the authors’ description of how engagement is rooted in long-standing public relations and corporate marketing discourses, and in light of the historical and structural foundations of anti-Americanism, this contemporary public diplomacy strategy is shown …

Israel, Palestine And The Benefits Of Waging War Through Twitter, Katina Michael

Faculty of Engineering and Information Sciences - Papers: Part A

Warfare, as we know, has gone digital, its volleys and counterattacks rattled out 140 characters at a time. Historically, nation states with superior military prowess have been in a position of influence, and are often dubbed superpowers. But in the post Cold War era, such geopolitical giants have not had a monopoly in terms of technological interventionism. Terrorist regimes have lifted the veil on conventional warfare and sought non-traditional methods to attack their counterparts. So-called "rogue states", such as Iran and North Korea, have been accused of hiding weapons of mass destruction (WMD) and developing nuclear programs. Today asymmetrical attacks …
