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 …

Nonprofit News, News Industrial Subsidies, And The Rise Of Citizen Journalism, Roger A. Lohmann

Faculty & Staff Scholarship

In this article three important policy questions are suggested in light of signs of recent growth of nonprofit news and the possibility of a great deal more similar growth in the future: 1) Does nonprofit news production pose a plausible solution to the economic troubles of the U.S. news industry? 2) Would industrial subsidies of nonprofits, like those for “welfare state” health and human services co-production offer a potential solution to the economic problems of the U.S. news industry? 3) Can the currently evolving internet-based system of news production by volunteer citizens be sustainable in the long run?

Demonstration: Dynamic Sensor Registration And Semantic Processing For Ad-Hoc Mobile Environments (Semmob), Pramod Anantharam, Gary Alan Smith, Josh Pschorr, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

SemMOB enables dynamic registration of sensors via mobile devices, search, and near real-time inference over sensor observations in ad-hoc mobile environments (e.g., fire fighting). We demonstrate SemMOB in the context of an emergency response use case that requires automatic and dynamic registrations of sensor devices and annotation of sensor observations, decoding of latitude-longitude information in terms of human sensible names, fusion and abstraction of sensor values using background knowledge, and their visualization using mash-up.

Using Social Influence To Predict Subscriber Churn, Derek Doran, Veena Mendiratta, Chitra Phadke, Dan Kushnir, Huseyin Uzunalioglu

Kno.e.sis Publications

The saturation of mobile phone markets has resulted in rising costs for operators to obtain new customers. These operators thus focus their energies on identifying users that will churn so they can be targeted for retention campaigns. Typical churn prediction algorithms identify churners based on service usage metrics, network performance indicators, and demographic information. Social and peer-influence to churn, however, is usually not considered. In this paper, we describe a new churn prediction algorithm that incorporates the influence churners spread to their social peers. Using data from a major service provider, we show that social influence improves churn prediction and …

Understanding User Triads On Facebook, Derek Doran, Alberta De La Rosa Algarin, Swapna S. Gokhale

Kno.e.sis Publications

Contemporary approaches that analyze user behavior on online social networks only consider interactions among dyads, which are pairs of directly connected users. A large body of sociological work, however, suggests that mutual connections among users can influence their activities, leading to differences between two- and three-way interactions. This paper explores the dynamics of triads among Facebook users based on the wall posts from the New Orleans regional network. Initially, each connection is categorized as a close friendship or an acquiantance, contingent on the number of wall posts exchanged. Subsequently, the impact of different types of connections comprising triads is examined …

Is Belief Larger Than Fact: Expectations, Optimism And Reality For Translational Stem Cell Research, Tania M. Bubela, Matthew D. Li, Mohamed Hafez, Mark Bieber, Harold Atkins

Office of the Provost

Background: Stem cell (SC) therapies hold remarkable promise for many diseases, but there is a significant gulf between public expectations and the reality of progress toward clinical application. Public expectations are fueled by stakeholder arguments for research and public funding, coupled with intense media coverage in an ethically charged arena. We examine media representations in light of the expanding global landscape of SC clinical trials, asking what patients may realistically expect by way of timelines for the therapeutic and curative potential of regenerative medicine?
Methods: We built 2 international datasets: (1) 3,404 clinical trials (CT) containing 'stem cell*' from ClinicalTrials.gov …

How I Would Like Semantic Web To Be, For My Children., Raghava Mutharaju

Kno.e.sis Publications

Semantic Web, since its inception, has gone through lot of developments in its relatively nascent existence; right from people's perception, to the standards and to its adoption by the industry and more importantly by the scientific community. This impressive growth only seems to increase. In this paper, we project this growth to the next 10 years and highlight some of the facets on which Semantic Web could have a major impact on. We also present the challenges that Semantic Web and its community has to deal with in order to get there.

An Efficient Bit Vector Approach To Semantics-Based Machine Perception In Resource-Constrained Devices, Cory Andrew Henson, Krishnaprasad Thirunarayan, Amit P. Sheth

Kno.e.sis Publications

The primary challenge of machine perception is to define efficient computational methods to derive high-level knowledge from low-level sensor observation data. Emerging solutions are using ontologies for expressive representation of concepts in the domain of sensing and perception, which enable advanced integration and interpretation of heterogeneous sensor data. The computational complexity of OWL, however, seriously limits its applicability and use within resource-constrained environments, such as mobile devices. To overcome this issue, we employ OWL to formally define the inference tasks needed for machine perception – explanation and discrimination – and then provide efficient algorithms for these tasks, using bit-vector encodings …

To engage the domain experts in …

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 …

This project discusses the best ways nonprofits can maximize their Facebook usage. Facebook is an easy way for nonprofits to communicate with their target audiences and have consistent communication. Friends of Hearst Castle was the nonprofit I worked with to help create and implement a Social Media Plan. …

Cognitive And Social Factors Affecting The Use Of Wikipedia And Information Seeking, Siyoung Chung

Research Collection Lee Kong Chian School Of Business

Wikipedia, the free online encyclopedia, is the preferred choice among resources used by college students to meet their research needs. However, Wikipedia has been criticized for its low information quality, lack of accountability, inconsistency, and vulnerability to vandalism. Despite the warnings and concerns voiced by academia, online learning tools such as Wikipedia will continue their rise as major learning resource in today's classroom. Using a sample of 184 college students, the study proposed theoretical models to test the effects of internal beliefs, motivations, and social influences on Wikipedia use and information-seeking, and further empirically tested those models. The findings of …

The Aftermath Of Aftermath: The Impact Of Digital Music Distribution On The Recording Industry, Michael Mccubbin

The University of New Hampshire Law Review

[Excerpt] “This article will address the impact the shift from hard-copy recordings to digital music distribution has had on the recording industry. Specifically, it will apply F.B.T. Productions v. Aftermath Records, which correctly held that a label’s relationship with third-party-digital-music-providers is that of licensor-licensee, to the modern music industry. Based on this holding, record labels need to reconsider their relationships with artists, and create new business models that rely on licensing music, rather than the traditional sale-based distribution model. The decision in Aftermath will lead to increased royalties for artists in the Digital Age. This article will analyze the impact …

Computing Perception From Sensor Data, Payam Barnaghi, Frieder Ganz, Cory Andrew Henson, Amit P. Sheth

Kno.e.sis Publications

This paper describes a framework for perception creation from sensor data. We propose using data abstraction techniques, in particular Symbolic Aggregate Approximation (SAX), to analyse and create patterns from sensor data. The created patterns are then linked to semantic descriptions that define thematic, spatial and temporal features, providing highly granular abstract representation of the raw sensor data. This helps to reduce the size of the data that needs to be communicated from the sensor nodes to the gateways or highlevel processing components. We then discuss a method that uses abstract patterns created by SAX method and occurrences of different observations …
