As online communities become more important in young people's lives, it is important to consider who the active users are in these digital environments. Previous research has looked at the way leaders emerge in adult communities, but scholarship on young people's participation patterns has been less robust. This paper looks at the phenomenon of “super‐users” or the leaders and vocal participants,...
In this article we introduce the concept of search transitions as a unit for measuring the effort invested by searchers in information retrieval interaction. The concept is discussed and compared to traditional measures of effort, such as time. To investigate the usability of the search transition measure we have performed an analysis of 149 logs in an IR system indexing a collection of 650.000 Wikipedia...
This article tackles the task of retrieving very short documents via even shorter queries. The problem on hand may relate to the retrieval of tweets, image and table captions, short text messages (SMS) and sponsored retrieval among others. In such cases, document and/or query expansion using thesauri and other external resources (e.g., Wikipedia) usually available on the World Wide Web (WWW) are proven...
It has been recognized that most seniors prefer to age in a place with familiar surroundings until their health makes this impossible. In an attempt to address the aging phenomenon, as well as recognize seniors' preference, we worked with a Canada‐based company that develops a sensor‐based home monitoring system for people to monitor the home activities of independently living seniors. Our role was...
In this paper, we examined the effects of information searchers' familiarity with task topics on their search behaviors, in different task types. Data were collected in a controlled laboratory experiment, participated by 32 undergraduate journalism students. Each participant searched on four tasks varying along four task facets: task product (being factual or a mix of intellectual/factual), level...
This study seeks to explore whether or not information professionals who deal consistently with various technologies are familiar with Facebook and are ready to incorporate it within their organizations. The current study uses the Technology Acceptance Model (TAM), a well‐known theory for explaining individuals' technology behaviors, as well as the “Big Five” model of personality, as theoretical bases...
This paper explores topic aspect (i.e., subtopic or facet) classification for collections that contain more than one language (in this case, English and Chinese), and investigates several key technical issues that may affect the classification effectiveness. The evaluation model assumes a bilingual user who has found some documents on a topic and identified a few passages in each language on specific...
Document level sentiment analysis, the task of determining whether the sentiment expressed in a document is positive or negative, is commonly performed by supervised methods. As with all supervised tasks, obtaining training data for these methods can be expensive and time‐consuming. Some semi‐supervised approaches have been proposed that rely on sentiment lexicons. We propose a novel supervised and...
This paper presents and evaluates a collaborative attribution strategy based on six authorship attribution schemes representing the two main paradigms used in authorship studies. Based on very frequent words as features, the classical paradigm (or similarity‐based methods) proposes to compute an intertextual distance between the disputed text and the different author profiles (concatenation of their...
Social question and answer sites (SQAs) are increasingly popular knowledge sharing platforms. In this paper, we outline how an SQA site functions as a social learning community. The success of an SQA site depends not only on effectively organizing and delivering information, but also on whether it can provide the cues needed by community members to successfully learn to be productive contributors...
The discovery and visualization of temporal sequence of personalized academic research can enhance the ability for discovering the latent trend of interests to information seekers. In this paper, we propose a definition of weighted co‐occurring keywords time gram and use it as a basic unit to analyze the temporal information in existed keywords collection. We further propose a method to get the temporal...
In recent decades many countries have leveraged information and communication technologies to facilitate interaction between citizens, businesses and governments. By enhancing government efficiencies and streamlining governance systems, countries expect to strengthen public service deliveries and to improve public and private sector interactions. Open public data is expected to bring better access...
Equity of access is an imperative in the global information world of the 21st Century. For the information outsider however, or those who might be disenfranchised by social constructions, economic, legal, educational, or political circumstances, or geographical location, information poverty is a disheartening reality (Chatman, 1992; 1996; 2000; Burnett, Bessant, & Chatman, 2001). The functions...
The benefits of knowledge organization (KO) systems have been documented by many (e.g., Hodge, 2000; Hjørland, 2008; Abbas, 2010). Despite known advantages, KO investment appears to vary widely among and within industry, research, and educational communities. Data specific to KO investment and the impacts (gains and losses) is limited. The societal benefits of improving KO systems may thus be under‐appreciated,...
Research design is a vital consideration when embarking on any research venture. The careful selection of method (or combination of methods) and project design are integral to obtaining funding, completing a successful study, and having your research accepted for presentation and publication. This panel adopts a format similar to the Antiques Roadshow to focus on research design, with interactive...
As more information is digitized or born online, issues with assessment and preservation, in the forms of determining, reviewing, and describing it, increase. This is particularly true for what we might term high‐stakes information, or information that if not carefully assessed or preserved can result in harmful consequences. With the premise that scholarly information is high‐stakes information,...
In a previous work we tested users' preferences with systems that allow to store and retrieve information either using tags or folders. In the current study we asked participants sampled from the same population about their attitudes towards tags by using a questionnaire (N = 168). We then compared the results regarding attitudes gathered in this study with the ones testing actual behavior gathered...
The panel will discuss the importance of understanding the research environment for providing effective information and technology support to researchers, and the implications for curricula in professional education. Our specific context is growing involvement of academic libraries and information services in managing research data, but the issues raised have wider implications for educating and developing...
