The paper discusses the design, development and evaluation of a task‐based digital library, the Digital Work Environment (DWE), for the academic community of higher education institutions (HEI) with Nanyang Technological University, Singapore, as a test case. Three different information organisation approaches (alphabetical, subject category and task‐based) were used to organise the wide range of heterogeneous information resources that were interfaced to DWE. A user evaluation study using a series of task scenarios was carried out to gauge the effectiveness and usefulness of DWE and these information organisation approaches. The time taken by respondents to identify and access the relevant information resources for individual tasks was also measured. The findings show that the task‐based approach took the least time in identifying information resources. Regression analysis of information resource location time with gender, age, computer experience and digital resource experience of the participants are also reported.

The purpose of this paper is to describe the multi-tiered framework supported by the NDLTD-Taiwan systems to achieve the collaboration and cooperation with universities and colleges in building electronic theses collection in Taiwan.

The paper describes the outcomes of multi-tiered framework, its user roles, tasks, and thesis-specific workflow, as well as the function for simulating user roles.

The framework is the result of supporting both the two-tiered and the three-tiered frameworks on the NDLTD-Taiwan systems platform. The design guidelines emerged out of the outcomes of task analysis.

The multi-tiered design not only accommodates graduation procedures for member universities and colleges, but also supports bibliographic control and collections building.

The paper shows that the multi-tiered design, which emerged out of the existing theses processes of member institutions, is inclusive. The framework allows member universities and colleges to choose an appropriate framework, either two-tiered or three-tiered, for managing their e-theses processes. In addition, role simulation allows the NCL administrator to reproduce problems encountered by the users to help troubleshooting.

Purpose – The purpose of this paper is to describe research undertaken for the European Internet Accessibility Observatory (EIAO) project. It aims to demonstrate how, using a task‐based approach, statistical measures can be applied to an initial assessment of a web site's accessibility, which could then be applied to further assessments to provide an evolving picture of the ongoing accessibility of a web site. Design/methodology/approach – Task‐based assessments were used to assess the accessibility of web sites, using quantitative and qualitative analysis. The findings from this approach were mapped onto a probabilistic model, developed to assess the probability of an accessibility barrier relating to a specific feature or features of a web site. Findings – The paper finds that providing participants with a task instead of allowing them to randomly explore and evaluate a web site yielded more comparable results. For the EIAO project team, the benefit of the task‐based approach was that it allowed them to compare the user testing results with the results of the automated testing tool developed by the project. From the aggregation models included in the analysis, the most appropriate model and parameters were selected, and adjustments were made according to the comparison outcome. Research limitations/implications – Due to resource limitations and efficiency requirements, the assessments undertaken were limited to automatic evaluation, which could also be tested by the users. Therefore not all accessibility barriers in a web site could be identified. Despite this, it is felt that the outcome of the automatic analysis can be utilised as indicator for the overall accessibility of the web site. Originality/value – This paper provides a framework for web designers, commissioners, and policy makers to undertake a user focussed assessment of the accessibility of their web sites, which could be used in conjunction with other assessment methods.

The purpose of this paper is to describe a methodology for characterization of the robot environment to help solve such problem as designing an optimal agricultural robot for a specific agricultural task.

Defining and characterizing a task is a crucial step in the optimization of a task-specific robot. It is especially difficult in the agricultural domain because of the complexity and unstructured nature of the environment. In this research, trees are modeled from orchards and are used as the robot working environment, the geometrical features of an agricultural task are investigated and a method for designing an optimal agricultural robot is developed. Using this method, a simplified characteristic environment, representing the actual environment, is developed and used.

Case studies showing that the optimal robot, which is designed based on the characteristic environment, is similar to the optimal robot, which is designed based on the actual environment (less than 4 per cent error), is presented, while the optimization run time is significantly shorter (up to 22 times) when using the characteristic environment.

This paper proposes a new concept for solving the robot task-based optimization by the analysis of the task environment and characterizing it by a simpler artificial task environment. The methodology decreases the time of the optimal robot design, allowing to take into account more details in an acceptable time.

Design and construction of indexing languages require thorough knowledge and understanding of the information environment. This empirical study investigated a mixed set of methods (group interviews, recollection of information needs and word association tests to collect data; content analysis and discourse analysis to analyse data) to evaluate whether these methods collected the data needed for work domain oriented thesaurus design. The findings showed that the study methods together provided the domain knowledge needed to define the role of the thesaurus and design its content and structure. The study was carried out from a person‐insituation perspective. The findings reflected the information environment and made it possible to develop a thesaurus according to the characteristics of the work domain. It seemed more difficult to capture the needs of the individual user and adapt the thesaurus to individual characteristics.

Performing tasks in public spaces can be demanding due to task complexity. Systems that can keep track of the current task state may help their users to successfully fulfill a task. These systems, however, require major implementation effort. The purpose of this paper is to investigate if and how a mobile information assistant which has only basic task-tracking capabilities can support users by employing a least effort approach. This means, we are interested in whether such a system is able to have an impact on the way a workflow in public space is perceived.

The authors implement and test AIRBOT, a mobile chatbot application that can assist air passengers in successfully boarding a plane. The authors apply a three-tier approach and, first, conduct expert and passenger interviews to understand the workflow and the information needs occurring therein; second, the authors implement a mobile chatbot application providing minimum task-tracking capabilities to support travelers by providing boarding-relevant information in a proactive manner. Finally, the authors evaluate this application by means of an in situ study (n = 101 passengers) at a major European airport.

The authors provide evidence that basic task-tracking capabilities are sufficient to affect the users’ task perception. AIRBOT is able to decrease the perceived workload airport services impose on users. It has a negative impact on satisfaction with non-personalized information offered by the airport, though.

The study shows that the number of features is not the most important means to successfully provide assistance in public space workflows. The study can, moreover, serve as a blueprint to design task-based assistants for other contexts.

Increasing flexibility and student mobility are among the most important objectives of today’s universities. The purpose of this paper is to discuss the effects of student exchange process (SEP) on a campus management system (CMS), compare different models and recommend an improvement handling transfer process.

A comprehensive literature review of how credit transfer is handled in today’s CMS was conducted to understand the information management methods used in the student transfer process. On this basis, a flexible task-based system design is recommended to facilitate the transfer of educational gains between universities. For evaluating the effectiveness of different system designs in the SEP, the duration of information processing process steps was measured quantitatively via on-site observations and user interview in a university’s horizontal, vertical and the Erasmus student exchange (SE) data.

Building a flexible system design based on a loosely coupled mapping between curriculum and educational activities, and increasing the self-management capabilities of a student will facilitate managing SE data in an integrated environment and reduce the university staff’s workload considerably.

To the author’s knowledge, this is the first study making quantitatively measurement and comparison of different credit transfer methods of CMSs. Based on this result, the authors have recommended a new flexible method that supports increasing a student’s self-administration capabilities, reducing the workload of university staff, and contributes academic mobility.

The purpose of this paper is to present extensions of Semantic MediaWiki for the purpose of technology forecast and technology monitoring. The user friendliness and applicability of the components is evaluated by task-based user studies.

Based on the requirements given by potential end users (technology experts), visualization possibilities were designed and implemented. Potential users used the new features of technology forecast and monitoring within a semantic wiki and were controlled regarding the effectiveness.

Although semantic wikis are ideal tools for knowledge management in industry settings, especially due to their user-friendly way of storing and retrieving knowledge, they have rarely been used for technology forecast and monitoring purposes so far. The authors show that the additional requirements for such purposes can be met and provide established technology analysis possibilities within Semantic MediaWiki. In that way, a new application area of Semantic MediaWiki is introduced.

Tools and techniques for Semantic MediaWiki are presented, opening the application area of Semantic MediaWiki for technology and innovation management. The research provides evidence that the open-source implemented visualization and storage techniques can be applied in real-world settings, where so far mainly costly dedicated software has had to be used.

The purpose of this study is to explore the impact of mobile learning platforms on users' study efficiency and develop cognitive indicators to evaluate users' study efficiency on mobile learning platforms.

Layout style was the only independent factor that was investigated. A between-group experimental design was employed. Eye movement data were recorded during the experiment, following which participants were asked to complete an after-scenario questionnaire. This study evaluated the usability of the proposed new design using both subjective and objective data. The computer system usability questionnaire V3 (CSUQ) was used to measure subjective data. For the eye-tracking measure, gaze entropy, the proportion of fixation count and duration of each AOI were calculated. Gaze entropy reflects the complexity of information organization. Fixation counts and AOI duration represent the difficulty of information processing and attention distribution, respectively during the task.

The results indicated that interface layout presents significant effects on user's learning efficiency, usability and cognitive load. Sequential layout improved efficiency and satisfaction among participants and reduced information complexity. The results provided useful insights for designers whose goal is to improve user's learning efficiency under mobile learning scheme.

This study investigated the effects of interface layout on usability, user performance and cognitive load using subjective ratings and eye-tracking technology. Gaze entropy was used to measure the complexity of information organized by the interface design. Fixation count and duration proportion were used to identify the difficulty of information processing and distinguish users' distribution of cognitive resources. The results indicated that a vertical layout panel design was more efficient than a horizontal layout panel design. The design implications of the eye tracking indicators and research results were then summarized. This study is expected to encourage designers to optimize their design proposals using eye tracking testing.

Extends the concept of e‐service to the whole phase of manufacturing. Develops an e‐service platform prototype based on this concept with Java Web solution including the mobile agent broking technologies and application service provider (ASP) principle. The key point to implement the platform is to enable an open Web information service infrastructure for the whole product manufacturing chain. Inside this infrastructure, product‐specific online manufacturing system can be created by means of using a kind of bidding model. All users participating in the manufacturing process are able to cooperatively finish manufacturing tasks in real time through sharing the same platform. With the help of BOM flow, the global information service flow can be controlled easily. In addition, the legacy hardware/software can also be encapsulated with aglets that are Java mobile agents. As to new ASP software packages, they can be configured simply via the plug and play mode to the e‐service platform. In this way, the on‐line networked manufacturing can be tested.
