Entity Linking On Microblogs With Spatial And Temporal Signals, Yuan Fang, Ming-Wei Chang
Research Collection School Of Computing and Information Systems
Microblogs present an excellent opportunity for monitoring and analyzing world happenings. Given that words are often ambiguous, entity linking becomes a crucial step towards understanding microblogs. In this paper, we re-examine the problem of entity linking on microblogs. We first observe that spatiotemporal (i.e., spatial and temporal) signals play a key role, but they are not utilized in existing approaches. Thus, we propose a novel entity linking framework that incorporates spatiotemporal signals through a weakly supervised process. Using entity annotations1 on real-world data, our experiments show that the spatiotemporal model improves F1 by more than 10 points over existing systems. …

Effect Of Convergence Culture On Spectatorship, Amanda Marcus
e-Research: A Journal of Undergraduate Work
Media convergence has changed how we receive and process information. No longer are we passive spectators, but we are part of the media we consume. Because of the explosion of technology since the turn of the century and a new definition of spectatorship, producers of media can no longer control how their messages are received; they have to engage their audience and listen to feedback in order to remain functioning. Fellow peers serve as informants or as a new source of media. This also affects our individual identities, which shapes our cultural identity. Social media enables us to present ourselves …

Patrons Cataloging? The Role And Quality Of Patron Tagging In Item Description, William Lund, Allyson Washburn
William Lund
With the advent of Web 2.0 technologies, user participation in the description and evaluation of content has come to the library. User tagging is almost a given in applications such as Del.icio.us, Flickr, and LibraryThing. The question is whether tagging provided by users with their own motivations is better in some sense then descriptions provided by professionals. Is the tagging provided by the wisdom of the crowd a better description of an item?

Community Connections: Exploring The Constructive Potential Of Facebook For Civic Engagement, Sarah Ruth Martin
Dissertations and Theses
Recognizing the importance of civic engagement to the health of local communities and the overall success of a democracy, this research sought to better understand the relationship between online media use and civic engagement. Specifically, the constructive potential of the social networking site Facebook was explored using the theoretical framework of communication infrastructure theory (CIT; Ball-Rokeach, Kim, & Matei, 2001). Results of a cross-sectional survey with a national sample of 375 participants indicated that Facebook does hold potential for civic engagement. The two most important findings of the research were that Facebook facilitated connection to neighborhood storytelling and that connection …

Interdisciplinary Informatics Faculty Proceedings & Presentations
Pertinent questions on the measurement of social indicators are: the verification of data gained online (e.g., controlling for self-representation on social networks), and appropriate uses in community management and policy-making. Across platforms like Facebook, LinkedIn, Twitter, and blogging services, users (sub)consciously represent themselves in a way which is appropriate for their intended audience (Qui et al., 2012; Zhao et al., 2008). However, scholars in the social sciences and computer science have not yet adequately addressed controlling for self-representation, or the propensity to display or censor oneself, in their analyses (Zhao et al., 2008; Das and Kramer, 2013). As such researchers …

We describe our demonstration of CLEar (Clairaudient Ear), a real-time online platform for detecting, monitoring, summarizing, contextualizing and visualizing bursty and viral events, those triggering a sudden surge of public interest and going viral on micro-blogging platforms. This task is challenging for existing methods as they either use complicated topic models to analyze topics in a off-line manner or define temporal structure of fixed granularity on the data stream for online topic learning, leaving them hardly scalable for real-time stream like that of Twitter. In this demonstration of CLEar, we present a three-stage system: First, we show …

Sharing Political News: The Balancing Act Of Intimacy And Socialization In Selective Exposure, Jisun An, Daniele Quercia, Meeyoung Cha, Krishna Gummadi, Jon Crowcroft
Research Collection School Of Computing and Information Systems
One might think that, compared to traditional media, social media sites allow people to choose more freely what to read and what to share, especially for politically oriented news. However, reading and sharing habits originate from deeply ingrained behaviors that might be hard to change. To test the extent to which this is true, we propose a Political News Sharing (PoNS) model that holistically captures four key aspects of social psychology: gratification, selective exposure, socialization, and trust & intimacy. Using real instances of political news sharing in Twitter, we study the predictive power of these features. As one might expect, …

User attribute extraction on social media has gain considerable attention, while existing methods are mostly supervised which suffer great diffi- culty in insufficient gold standard data. In this paper, we validate a strong hypothesis based on homophily and adapt it to ensure the certainty of user attribute we extracted via weakly supervised propagation. Homophily, the theory which states that people who are similar tend to become friends, has been well studied in the setting of online social networks. When we focus on age attribute, based on this theory, online friends tend to have similar age. In this work, we take …

Interestingness-Driven Diffussion Process Summarization In Dynamic Networks, Qiang Qu, Siyuan Liu, Christian Jensen, Feida Zhu, Christos Faloutsos
Research Collection School Of Computing and Information Systems
The widespread use of social networks enables the rapid diffusion of information, e.g., news, among users in very large communities. It is a substantial challenge to be able to observe and understand such diffusion processes, which may be modeled as networks that are both large and dynamic. A key tool in this regard is data summarization. However, few existing studies aim to summarize graphs/networks for dynamics. Dynamic networks raise new challenges not found in static settings, including time sensitivity and the needs for online interestingness evaluation and summary traceability, which render existing techniques inapplicable. We study the topic of dynamic …

Facebook is among the top used websites in the world, and research has shown that Facebook use is related to individual personality characteristics such as well-being and self-esteem. This study builds on previous research, expanding to investigate attachment-related anxiety and avoidance and relational certainty. The current study examined relationships between Facebook use (both general and for surveillance) and relational certainty, attachment-related anxiety and avoidance, and self-esteem in undergraduate students (N = 261). Online methods were used for data collection, and individuals with their relationship displayed on Facebook reported more relational certainty; however, the more time they spent on the site, …

Opinions are central to almost all human activities by influencing greatly the decision making process. In this thesis, we present the problems of mining issues, extracting entities and suggestive opinions towards the entities, detecting thoughtful comments, and extracting stances and ideological expressions from online comments in the sociopolitical domain. This study is essential for opinion mining applications that are beneficial for policy makers, government sectors and social organizations. Much work has been done to try to uncover consumer sentiments from online comments to help businesses improve their products and services. However, sociopolitical opinion mining poses new challenges due to complex …

Toward A Uses And Gratification's Model Of Twitter, Philip Ryan Johnson
Theses - ALL
This study proposed a uses and gratifications model of Twitter, an internet medium and micro-blog--a platform with both mass and interpersonal communication features for sending short messages to others. A survey was conducted among 242 Twitter users to test the model, including a standard investigation of gratifications sought and gratifications obtained of Twitter usage. In addition, expectations and availability of usage behaviors from McLeod and Becker's (1981) uses and gratifications model were examined. In the model, expectations were conceptualized as user expectations of satisfaction and operationalized as the difference between users' gratifications sought and gratifications actually obtained. Usage behavior availability …

Framing Urban Change: Gentrification Discourses In The Media Coverage Of The Gülbol Eviction In Berlin, Eric Daniel Gedenk
Masters Theses
This thesis examines gentrification discourses in Berlin by highlighting an extraordinarily large protest sparked by the eviction of the Gülbol family—long-time residents of Berlin who immigrated to Germany from Turkey. Media outlets chose to frame the event in very different ways. I analyze articles from various media sources in an attempt to discover how these sources chose to frame this event, then analyze how these frames are applied to the general gentrification discourse in Berlin. Non-traditional, or “advocacy” media outlets used technology to break away from mass media frames on the subject and frame the event as governmental oppression and …

Generating Supplementary Travel Guides From Social Media, Liu Yang, Jing Jiang, Lifu Huang, Minghui Qiu, Lizi Liao
Research Collection School Of Computing and Information Systems
In this paper we study how to summarize travel-related information in forum threads to generate supplementary travel guides. Such summaries presumably can provide additional and more up-to-date information to tourists. Existing multi-document summarization methods have limitations for this task because (1) they do not generate structured summaries but travel guides usually follow a certain template, and (2) they do not put emphasis on named entities but travel guides often recommend points of interest to travelers. To overcome these limitations, we propose to use a latent variable model to align forum threads with the section structure of well-written travel guides. The …

On Macro And Micro Exploration Of Hashtag Diffusion In Twitter, Yazhe Wang, Baihua Zheng
Research Collection School Of Computing and Information Systems
This exploratory work studies hashtag diffusion in Twitter. The analysis is conducted from two aspects. From the macro perspective, we study general properties of hashtag diffusion, and classify hashtags into three main classes based on their temporal dynamics referred as 'single spike', 'multi-spikes', and 'fluctuation', and find that each of these classes has some unique characteristics. From the micro perspective, we investigate individual diffusion.We adopt Edelman's 'topology of influence' theory to identify four type of users with different influence levels in diffusion based on their dynamic retweet behaviors. The results of our study are useful for gaining more insights of …
