Analysing and evaluating usefulness and usability in electronic information services
TLDR
A model, which analyses the attributes of the electronic information services' components that affect user interaction and correlates them in the usefulness and usability evaluation process, suggests that user interaction is affected equally by content and system characteristics.Abstract:
Digital libraries, e-journal platforms, portals, e-prints and other web-based information systems provide services supporting users to perform intense work tasks that require complex interaction activities. The main components of such services are the users, the offered content and the system on which they are performed. This paper presents a model, which analyses the attributes of the electronic information services' components that affect user interaction and correlates them in the usefulness and usability evaluation process. An experimental study traces the relations between usefulness and usability, indicating that these evaluation parameters are interconnected and users do not find discriminating differences between them. The analysis of the content and system attributes suggests that user interaction is affected equally by content and system characteristics. Finally, the study illustrates users' preference for the attributes that constitute a useful system in contrast to those that support usability.read more

TL;DR: A large-scale survey of current DL evaluation activities has resulted in a description of the state of the art in the field, and a new framework for the evaluation of DLs, as well as for recording, describing and analyzing the related research field is proposed.

Exploring usefulness and usability in the evaluation of open access digital libraries
TL;DR: The present study explores the concepts of usefulness and usability in the evaluation of an e-print archive and demonstrates that several attributes of usefulness, such as the level and the relevance of information, and usability, as well as functionalities commonly met in these systems, affect user interaction and satisfaction.

Perceived Usefulness, Perceived Ease of Use, and User
TL;DR: Regression analyses suggest that perceived ease of use may actually be a causal antecdent to perceived usefulness, as opposed to a parallel, direct determinant of system usage.

Perceived usefulness, perceived ease of use, and user acceptance of information technology
TL;DR: In this article, the authors developed and validated new scales for two specific variables, perceived usefulness and perceived ease of use, which are hypothesized to be fundamental determinants of user acceptance.

Information Systems Success: The Quest for the Dependent Variable
TL;DR: A large number of studies have been conducted during the last decade and a half attempting to identify those factors that contribute to information systems success, but the dependent variable in these studies-I/S success-has been an elusive one to define.

Inside the Search Process: Information Seeking from the User's Perspective.
TL;DR: A model of the information search process is presented derived from a series of five studies investigating common experiences of users in information seeking situations, suggesting a gap between the users’ natural process of information use and the information system and intermediaries’ traditional patterns of information provision.
