Adding the Dimension of Knowledge Trading to Source Impact Assessment: Approaches,Indicators, and Implications
Erjia Yan and Yongjun Zhu

While there have been efforts at evaluating different aspects of journal impact, the dimension of knowledge trading is largely absent. To fill the gap, this study employed a set of trading-based indicators, including weighted degree centrality, Shannon entropy, and weighted betweenness centrality, to assess sources’ trading impact.

A Note Concerning Primary Source Knowledge
Harry M. Collins, Luis Reyes-Galindo, and Paul Ginsparg

We present the results of running 4 different papers through the automated filtering system used by the open access preprint server “arXiv” to classify papers and implement quality control barriers. [Read more]

Search Task Features in Work Tasks of Varying Types and Complexity
Miamaria Saastamoinen and Kalervo Järvelin

Information searching in practice seldom is an end in itself. In work, work task (WT) performance forms the context, which information searching should serve. Therefore, information retrieval (IR) systems development/evaluation should take the WT context into account. [Read more]

A longitudinal study of user queries and browsing requests in a case-based reasoning retrieval system
Wu He and Xin Tian

This article reports on a longitudinal analysis of query logs of a web-based case library system during an 8-year period (from 2005 to 2012). The analysis studies 3 different information-seeking approaches: keyword searching, browsing, and case-based reasoning (CBR) searching provided by the system by examining the query logs that stretch over 8 years.

Analysis of Change in Users’ Assessment of Search Results Over Time
Maayan Zhitomirsky-Geffet, Judit Bar-Ilan, and Mark Levene

We present the first systematic study of the influence of time on user judgements for rankings and relevance grades of web search engine results. The goal of this study is to evaluate the change in user assessment of search results and explore how users’ judgements change. [Read more]

On the Feasibility of Predicting Popular News at Cold Start
Ioannis Arapakis, Berkant Barla Cambazoglu, and Mounia Lalmas

Prominent news sites on the web provide hundreds of news articles daily. The abundance of news content competing to attract online attention, coupled with the manual effort involved in article selection, necessitates the timely prediction of future popularity of these news articles. [Read more]

User Involvement and System Support in Applying Search Tactics
Iris Xie, Soohyung Joo, and Renee Bennett-Kapusniak

Both user involvement and system support play important roles in applying search tactics. To apply search tactics in the information retrieval (IR) processes, users make decisions and take actions in the search process, while IR systems assist them by providing different system features.

Understanding Users of Cloud Music Services: Selection Factors, Management and Access Behavior, and Perceptions
Jin Ha Lee, Rachel Wishkoski, Lara Aase, Perry Meas, and Chris Hubbles

Recent, rapid changes in technology have resulted in a proliferation of choices for music storage and access. Portable, web-enabled music devices are widespread, and listeners now enjoy a plethora of options regarding formats, devices, and access methods. [Read more]

Academics’ Behaviors and Attitudes Towards Open Access Publishing in Scholarly Journals
Jennifer Rowley, Frances Johnson, Laura Sbaffi, Will Frass, and Elaine Devine

While there is significant progress with policy and a lively debate regarding the potential impact of open access publishing, few studies have examined academics’ behavior and attitudes to open access publishing (OAP) in scholarly journals. [Read more]

Book Genre and Author Gender: Romance>Paranormal-Romance to Autobiography>Memoir
Mike Thelwall

Although gender differences are known to exist in the publishing industry and in reader preferences, there is little public systematic data about them. This article uses evidence from the book-based social website Goodreads to provide a large scale analysis of 50 major English book genres based on author genders. [Read more]

Identification of Long-Term Concept-Symbols Among Citations: Do Common Intellectual Histories Structure Citation Behavior?
Jordan A. Comins and Loet Leydesdorff

“Citation classics” are not only highly cited, but also cited during several decades. We explore whether the peaks in the spectrograms generated by Reference Publication Years Spectroscopy (RPYS) indicate such long-term impact by comparing across RPYS for subsequent time intervals. [Read more]

How Many Ways to Use CiteSpace? A Study of User Interactive Events Over 14 Months
Qing Ping, Jiangen He, and Chaomei Chen

Using visual analytic systems effectively may incur a steep learning curve for users, especially for those who have little prior knowledge of either using the tool or accomplishing analytic tasks. How do users deal with a steep learning curve over time? Are there particularly problematic aspects of an analytic process? [Read more]

The Scaling Relationship Between Citation-Based Performance and Coauthorship Patterns in Natural Sciences
Guillermo Armando Ronda-Pupo and J. Sylvan Katz

The aim of this paper is to extend our knowledge about the power-law relationship between citation-based performance and coauthorship patterns in papers in the natural sciences. We analyzed 829,924 articles that received 16,490,346 citations. The number of articles published through coauthorship accounts for 89%. [Read more]

The State and Evolution of U.S. iSchools: From Talent Acquisitions to Research Outcome
Zhiya Zuo, Kang Zhao, and David Eichmann

The Effect of Social Network Site Use on the Psychological Well-Being of Cancer Patients
Seyedezahra Shadi Erfani, Babak Abedin, and Yvette Blount

Social network sites (SNSs) are growing in popularity and social significance. Although researchers have attempted to explain the effect of SNS use on users’ psychological well-being, previous studies have produced inconsistent results. In addition, most previous studies relied on healthy students as participants; other cohorts of SNSs users, in particular people living with serious health conditions, have been neglected. [Read more]
