This poster presents the preliminary findings from the study, which aimed to explore the potential of inducing serendipitous news discovery in social gaming environment. Erdelez' (2004) model of Information Encountering was used as a theoretical foundation to create a social game site, which was intended to provide a relaxed natural foreground activity for players without their awareness about serendipitous...
Citation analysis, in addition to peer review, is one of the popular methods to assess faculty research performance. In some disciplines, the validity of citation counts for evaluating research has been proven by many studies. However, it should be used cautiously when different disciplines are concerned, because citation practices may vary across disciplines. Although there have been studies that...
Home offices are fused living and working spaces that lie at the intersection of the personal and the professional, blurring traditional divisions between these two domains. This poster reapproaches findings from a previous Masters thesis (Thomson, 2010)—which investigated information management in professional home offices—with an aim to highlight ways in which home office users negotiate and maintain...
Telepresence robotics is a sophisticated form of robotic remote control in which a human operator has a sense of being on location – that is, of being telepresent. I propose a demonstration of two telepresence robots, one floor model (VGo) and one tabletop model (KUBI). In this proposal, I describe the technology and briefly summarize the research that led to the purchase of the robots. The research...
Effects of mental demands on searchers were examined by controlling tasks complexity and by assessing searchers' working memory span (WM). The searchers were divided into low and high WM group. We expected that on more complex tasks all searchers would perform more searches to find more information. However, only high‐WM searchers performed more search actions. Low‐WM searchers performed about the...
In this paper, we explore the question of whether or not perceived time pressure and task difficulty are predictors of users' satisfaction with their search strategies. We conducted a crowd‐sourced user study in which 269 participants completed a total of 600 information‐seeking tasks. Based on self‐reported data gathered from post‐task questionnaires, we found that both perceived time pressure and...
This paper reports on an examination of why information searchers find search tasks difficult and the specific reasons they feel difficult. Data was collected through a controlled laboratory experiment with 32 participants, each working with 4 search tasks. They were asked in questionnaires, both before and after the tasks, for task difficulty ratings and their reasoning for giving those ratings....
Information visualization offers an opportunity to provide quick overviews and support exploration of the information landscape. However, there are many visualization techniques and layouts to choose from and some designs work better than others. The poster presents four hierarchical layouts developed in our FrbrVis prototype to display bibliographic work families and looks at user's perceptions of...
This paper presents the results of a preliminary study on non‐contributing behaviors among college‐aged Wikipedia users. By focusing on female freshmen, I investigated how college‐aged female students start establishing certain attitudes toward Wikipedia, how previous experience influences these perceptions, and how a new social environment has an impact on their perceptions. Based on in‐depth interviews...
Within the context of SNSs, particularly Facebook, this study aims to understand how young adults perceive the credibility of various information sources, how their information activities differ by those information sources, and how young adults' perception of credibility impacts their information activities. The results of an online survey demonstrated that young adults consider medical/health organizations...
The proliferation of genomic data and their widespread data reuse pose new challenges to effectively manage and curate genomic data. This study contributes towards better understanding of 156 genomics scientists' perception and priorities for metadata functional requirements in genome curation work. Our study was guided by previously identified twenty two metadata functional requirements (Willis,...
The information work of the United States Department of Agriculture in its first years as an independent federal agency—1862 to 1888—was exceptional and contested. It engaged the public to collect information relevant to farming, markets, and trade. Through a close historical analysis of the Department's annual reports and supplementary materials, I examine that information work and situate it within...
This poster reports on a work‐in progress project of building a digital library for metadata records of books published by Sonzogno between 1800 and 1943. Metadata records from seven major libraries that have Sonzogno collections were harvested and used for building a unified collection for this project. Omeka, open‐source software for building digital libraries, was used to host, manage, and provide...
Subject indexing is an intellectual intensive process that bears many inherent uncertainties. Existing subject index systems generally produce binary outcomes on whether assigning an indexing term or not, which does not sufficiently reflect to which extent the indexing terms are associated with documents. On the other hand, probabilistic models have seen great success in capturing the uncertainties...
This poster introduces a work‐in progress project focusing on text mining of health‐related questions that people post in social Q&A which they obtain and share information, advice, and experiences. 69,363 of health questions about Sexually Transmitted Diseases (STDs) posted from 2009 to 2012 were randomly collected from Yahoo! Answers and used for text mining and analysis in this study. A preliminary...
In this paper we describe the process of mapping researcher information from the Dutch National Academic Research and Collaborations Information System (NARCIS) to the VIVO ontology. Our goal is to use the VIVO ontology to accurately represent these researchers and their organizations, while remaining true to the native language and structure of the Dutch university. To achieve this, we first created...
Given that the rise of the Internet has greatly intensified information management problems in contemporary society, the historical perspective, or looking at the roots, is viewed by many as an indispensable component of the quest for practical solutions to information overload. This historical comparative study intends to narrow the gap in the existing knowledge about the impact of the Soviet military‐industrial...
We proposed an advanced tag method in which original tags are expanded and the semantic relations between original or expanded tags are used to extract key sentences from lecture speech transcripts. Then, to evaluate our proposed method, we compared it with two other methods, a tag method of using only original tags and a latent semantic analysis (LSA) method. As a result, the F measure mean (0.31)...
The interdisciplinary nature of the information field (iField) calls for a greater understanding of how iSchool scholars engage with information technology in their research. The purpose of this article is to study how much emphasis iSchool scholars put into studying technology, and how they conceptualize technology in their research. Using content analysis as our method of investigation, we coded...
