Abstract

Purpose

Previous research has focused on how trustworthiness can be evoked by the physical design of on‐screen characters (OSCs) within the e‐commerce interface. The purpose of this study is to investigate whether or not the OSCs representation, along with user differences, influence, how likeable, appropriate and trustworthy they are.

Design/methodology/approach

A web site was created for a simulated online bookseller and 183 people from various countries participated in the experiments. OSC representations were tested under four conditions in the main experiment: facial appearance (human‐like vs cartoon‐like) and gender (male vs female).

Findings

The results suggest that the human‐like characters are more likeable, appropriate and trustworthy in general terms. However, when perceived capabilities of OSCs are measured, a mismatch can occur between expectations and capabilities of the human‐like OSCs. In fact, cartoon‐like OSCs, especially female, had more positive effects on the web site interface.

Research limitations/implications

This study was limited to simulations of on‐screen scenarios. Future work, with access to the huge database required, could investigate the effects of truly interactive OSCs. Larger national sub‐samples would permit generalisations about cross‐cultural differences.

Practical implications

For e‐tailers and web designers, this study suggests critical design variables and response‐moderating variables that mediate the effects of OSCs in e‐retailing. It helps to understand customers' interaction needs in establishing and maintaining para‐social relationships, potentially increasing purchase intentions and persuasion.

Originality/value

The efficacy of different representations of OSCs to retail situations has been little investigated previously; this study measured how likeable, appropriate and trustworthy different OSC design formats are to different customer types.

Abstract

The user interface is defined as the link between the computer and the user. With organizations striving to increase productivity, focus must be shifted from the capabilities of the machine to the ability of the user. Research has shown that the use of the graphic user interface leads to a reduced learning curve for the user as well as a resulting efficiency increase. Provides an overview of research findings which support the use of the graphic interface to increase user productivity.

Abstract

Purpose

The underlying objective of this literature review was to investigate what kinds of semiotics researches have been employed in user interfaces design and usability evaluation, and how were they employed.

Design/methodology/approach

This research follows a systematic literature review process that consists of three key stages: planning the review, conducting the review, and reporting the review. Starting with an initial set of about 1,000 research articles, 65 were selected for this review, using an inclusion and exclusion criteria. Qualitative and quantitative data were extracted from the selected literatures following a data extraction strategy in six themes of data extraction. The extracted data were synthesized to formulate the stated research questions to obtain the review goals.

Findings

This systematic review identified research strengths, gaps, and challenges. Apart from this, further research possibilities were also explored in this review. For research, the review showed clear needs for more researches to increase both the number and the quality of studies that can be focused on the research gaps identified by this systematic review related to: outcome validation; cultural issues consideration; user interfaces of mobile applications and websites; semiotics perception in usability evaluation; and further improve the value and applicability of research ideas. For practice, the review showed the significance of semeiotics in user interface design and usability evaluation to develop users' intuitive interfaces for boosting the system's usability.

Originality/value

Based on a systematic literature review, the paper not only depicts the current status of semiotics research in user interface design and evaluation, but also provides a number of implications for research and practice. Thus, the review contributes to the scientific community of user interface design and evaluation, as well as suggesting the actual advances in the state of the practice in semiotics research on user interface.

Abstract

Like many operations research models, ambulance location models suffer from lack of practical implementation by those who could benefit from them. A major obstacle to adoption of such models is the emphasis their developers place on abstract mathematical principles, which overshadow the functional purpose of the models. This focus leads to impracticality in the presentation and usage of models, owing to such attributes as complex computer interfaces, cumbersome input and output procedures, and non‐intuitive presentation of results. Suggests a solution to these problems, in the form of a graphical interface system called ALIAS (Ambulance Location Identification and Analysis System).

Abstract

Describes the motivation, the initial implementation and tests carried out during the development of a combined discrete‐time and continuous‐simulation system intended primarily for the simulation of hybrid systems in manufacturing processes. The system, which is still under development, is the product of fusing two existing and independently developed packages, and the current implementation serves as a pilot design for evaluating the issues involved, both in terms of product development and in terms of the theoretical difficulties in combining discrete‐event and continuous‐time systems. The initial design has already been implemented and test simulations performed. Provides a superficial description of the system interface which is predominantly based on the existing interface of the discrete‐event simulator.

Abstract

Purpose

Aims to measure syllable aggregation consistency of Romanized Chinese data in the title fields of bibliographic records. Also aims to verify if the term frequency distributions satisfy conventional bibliometric laws.

Design/methodology/approach

Uses Cooper's interindexer formula to evaluate aggregation consistency within and between two sets of Chinese bibliographic data. Compares the term frequency distributions of polysyllabic words and monosyllabic characters (for vernacular and Romanized data) with the Lotka and the generalised Zipf theoretical distributions. The fits are tested with the Kolmogorov‐Smirnov test.

Findings

Finds high internal aggregation consistency within each data set but some aggregation discrepancy between sets. Shows that word (polysyllabic) distributions satisfy Lotka's law but that character (monosyllabic) distributions do not abide by the law.

Research limitations/implications

The findings are limited to only two sets of bibliographic data (for aggregation consistency analysis) and to one set of data for the frequency distribution analysis. Only two bibliometric distributions are tested. Internal consistency within each database remains fairly high. Therefore the main argument against syllable aggregation does not appear to hold true. The analysis revealed that Chinese words and characters behave differently in terms of frequency distribution but that there is no noticeable difference between vernacular and Romanized data. The distribution of Romanized characters exhibits the worst case in terms of fit to either Lotka's or Zipf's laws, which indicates that Romanized data in aggregated form appear to be a preferable option.

Originality/value

Provides empirical data on consistency and distribution of Romanized Chinese titles in bibliographic records.

Abstract

The TULIP (The University Licensing Project) data were integrated into the Carnegie Mellon Library Information System (LIS) in 1994. The bibliographic data were released to campus in April and the image data in June. All electronic library information resourc‐es—bibliographic, ASCII full text, image full text, and selected Telnet sessions—are available through the LIS user interface. This provides the user with “one‐stop shopping,” a longstanding goal of the LIS/Mercury project at Carnegie Mellon.

Abstract

Purpose

In view of the intensive spread of Coronavirus disease 2019 (COVID-19) and in order to reduce the rate of spread of this disease; the objective of this article is to propose an approach to detect in real time suspect person of Coronavirus disease 2019 (COVID-19).

Design/methodology/approach

The ubiquitous computing offers a new opportunity to reshape the form of conventional solutions for personalized services according to the contextual situations of each environment. The health system is seen as a key part of ubiquitous computing, which means that health services are available anytime, anywhere to monitor patients based on their context. This paper aims to design and validate a contextual model for ubiquitous health systems designed to detect in real time suspect person of COVID-19, to reduce the propagation of this infectious disease and to take the necessary instructions.

Findings

This paper presents the performance results of the COVID-19 detection approach. Thus, the reduction of the COVID-19 propagation rate thanks to the real-time intervention of the system.

Originality/value

Following the COVID-19 pandemic spread, the authors tried to find a solution to detect the disease in real time. In this paper, a real-time COVID-19 detection system based on the ontological description supported by Semantic Web Rule Language (SWRL) rules was developed. The proposed ontology contains all relevant concepts related to COVID-19, including personal information, location, symptoms, risk factors, laboratory test results and treatment planning. The SWRL rules are constructed from medical recommendations.
