Analyzing user interaction with the ViewFinder video retrieval system

Abstract

This study investigates interactive video retrieval. The basis for this study is that user-and search task-centric research in video information retrieval can assist efforts for developing effective user interfaces and help complement the existing corpus of video retrieval research by providing evidence for the benefits of evaluating systems using such an approach. Accordingly, the results were collected and analyzed from the perspective of certain users and search tasks (i.e., information needs). The methodology of this study employed specially designed interactive search experiments to examine a number of different factors in a video retrieval context, including those that correspond to search tasks of a particular domain, interface features and functions, system effectiveness, and user interactions. The results indicated that the use and effectiveness of certain interface features and functions were dependent on the type of search task, while others were more consistent across the full experiment. Also included is a review of prior research pertaining to visual search tasks, systems development, and user interaction. ViewFinder, the prototype system used to carry out the interactive search experiments of this study, is fully described.

Situated topic complexity in interactive video retrieval

“…With regard to specific sets of interface features, based on previous research, a typical keyword search and, more precisely, a transcript search has long been considered, in the most general sense, the best feature for retrieval accuracy (e.g., recall and precision) and for user satisfaction (Albertson, 2010a;Cooke et al, 2005;Yang, Wildemuth, & Marchionini, 2004). Based on such findings, one assumption could be that as the topics become increasingly difficult, possibly extending in duration, users may be even more inclined to gravitate toward the preferred keyword search in order to continuously re-formulate and re-execute textual queries until completion or discontinuation.…”

“…Although video retrieval studies have benefited from such models, researchers have had to adapt them due to the different makeup or structure of video (Albertson, 2010a). Video interface design frameworks should place emphasis not only on the interaction behaviors depicted in some previous models (Saracevic, 1997;Ingwersen, 1992), but also experiments analyzing the use of generalized interface features for retrieving video information.…”

Users' criteria of video digital libraries from a public affairs context

“…Effectiveness has also been assessed throughout search experiments, including follow-up studies from the TRECVID interactive search task, to evaluate if sufficient levels of retrieval are being reached across varying contexts [15,17,10,12]. Satisfaction is also significant as a basic metric, based on the importance of user-centered methods in digital library research, which can help assess effectiveness according to users' perceptions about the supportiveness of interface features and functions for user-assessed task completion [1]. These measures can and have been examined through other means, but this review of video digital library evaluation highlights the perceived importance of usability, generally speaking, which has previously been reported as the most important criterion for digital library use, with emphasis on the user interface and, more specifically, search and browse [17].…”

Effect of metacognitive strategies and verbal-imagery cognitive style on biology-based video search and learning performance

“…Video search is no exception. However, to date, few researchers have made the effort to explore the video search process (Albertson, 2010a;Burke, Snyder & Rager, 2009;Clifton & Mann, 2011;Lee & Lehto, 2013;Snelson & Elison-Bowers, 2009;Torres-Ramírez et al, 2014;Uzunboylu, Bicen & Cavus, 2011).This study aims to analyze and define the individual characteristics that affect students' abilities to effectively use video search engines. Previous studies have proposed that information-seeking behaviors are complex cognitive processes (Laxman, 2010;Lin & Tsai, 2007;Walraven, Brand-Gruwel, & Boshuizen, 2008).…”
