Adaptive search in consumer-generated content environment: an information foraging perspective

Liu, Fei 01 September 2016 (has links)
Inefficiencies associated with online information search are becoming increasingly prevalent in digital environments due to a surge in Consumer Generated Content (CGC). Despite growing scholarly interest in investigating users' information search behavior in CGC environments, there is a paucity of studies that explores the phenomenon from a theory-guided angle. Drawing on Information Foraging Theory (IFT), we re-conceptualize online information search as a form of adaptive user behavior in response to system design constraints. Through this theoretical lens, we advance separate taxonomies for online information search tactics and strategies, both of which constitute essential building blocks of the search process. Furthermore, we construct a research framework that bridges the gap between online information search tactics and strategies by articulating how technology-enabled search tactics contribute to the fulfillment of strategic search goals. We validate our research framework via an online experiment by recruiting participants from Amazon Mechanical Turk (AMT). Participants were tasked to perform searches on custom-developed online review websites, which were modeled after a popular online review website and populated with real restaurant review data. Empirical findings reveal that the provision of different search features indeed engenders distinct search tactics, thereby allowing users varying levels of search determination control and search manipulation control. In turn, both types of search controls affects users' result anticipation and search costs, which when combined, determine the efficiency of goal-oriented search strategy and the utility of exploratory search strategy. This study provides valuable insights that can guide future research and practice.

Training needs for electronic information use in the College of Law at the University of South Africa

Constable, Festus Tsepo 31 December 2007 (has links)
The purpose of this study was to investigate the training needs of law academics by examining their ability to use legal electronic information resources at Unisa effectively. Using the survey method, a questionnaire was used to collect data. The data was descriptively analysed. The study revealed that law academics are aware of the wide variety of electronic resources relevant to their work. Further, these academics possess the necessary basic skills to use these resources. However, the majority of academics do not have high levels of confidence in using specific electronic legal resources. This study concluded that, despite the library's provision of user training sessions for academics, training does not focus on legal electronic resources. The variety of responses revealed the diverse training needs of law academics. The study recommended that training needs analysis be conducted by subject librarians who would conduct specialised legal electronic training. / Information Sscience / M.Inf.
