Abstract
Purpose
The purpose of this paper is to conduct a big data analysis of public library operations and services of two cities in two countries by using the Chernoff face method.
Design/methodology/approach
The study is designed to evaluate library services by analyzing the Chernoff face. Big data on public libraries in London and Seoul were collected, respectively, from Chartered Institute of Public Finance and Accountancy and the Korean government’s website for drawing a Chernoff face. The association of variables and human facial features was decided by survey. Although limited in its capacity to handle a large number of variables (eight were analyzed in this study) the Chernoff face method does readily allow for the comparison of a large number of instances of analysis. A total of 58 Chernoff faces were drawn from the formatted data by using the R programming language.
Findings
The study reveals that most of the local governments in London perform better than those of Seoul. This consequence is due to the fact that local governments in London operate more libraries, invest more budgets, allocate more staff and hold more collections than local governments in Seoul. This administration resulted in more use of libraries in London than Seoul. The study validates the benefit of using the Chernoff face method for big data analysis of library services.
Practical implications
The Chernoff face method for big data analysis offers a new evaluation technique for library services and provides insights that may not be as readily apparent and discernible using more traditional analytical methods.
Originality/value
This study is the first to use the Chernoff face method for big data analysis of library services in library and information research.

Abstract
Purpose
The rise of social media and its resultant impact on brand management has become a critical factor in guarding the reputation of the firm. Consumer‐generated content has the potential to spread rapidly over social networks and the implications are that advertising as traditionally used by brand managers, now offers little control over the communication message. Brand managers need a better tool to gauge the changing mood in social media conversations. The purpose of this paper is to suggest a powerful method, Chernoff Faces, to compare six Sauternes wine brands based on social conversation measurement.
Design/methodology/approach
This study describes a source of data relating to wine brand visibility in social media, and then presents a simple yet powerful graphical tool for portraying this information. This tool facilitates the communication, understanding, and assimilation of the relevant information.
Findings
The findings of this paper are presented in six social media wine faces. Facial features are allocated to eyes, facial line, hair density and others to reflect “Social Mention” data measuring brand strength, positive and negative sentiment and related elements such passion for the brand. A brief subjective interpretation of the differences between the wine brands offers a match between Chernoff faces representation and historical data on the brands being compared.
Research limitations/implications
The paper has some limitations related to the dynamic nature of social media. This study provides more of a snapshot in time rather than an ultimate set of results. Future research could be done by closely monitoring the results for a set of brands over a period. A new option to overcome this by using longitudinal data is offered as a option in future research.
Originality/value
Since social media are multi‐dimensional and attempts to understand conversations it requires tracking different measures simultaneously. It is important to find the best way to portray and communicate this data so that wine marketing decision makers can quickly and easily compare changes in brand images. Using faces to accomplish this is an easy and novel way compared to more demanding multidimensional scaling techniques.

Abstract
Purpose
This paper proposes and tests a model to explain the outcomes of three different information presentation formats. Based on cognitive fit theory, information visualization formats that best fit task characteristics are expected to lead to improved decision-making outcomes. We apply the Judgment and Decision-Making framework (Bonner, 2008) to investigate how certain factors can impact decision quality.
Design/methodology/approach
This study tests whether certain production variance presentation formats (percentages, dollar amounts, and schematic faces), task complexity, understanding of the presentation format, motivation, and effort increase the accuracy of a supervisor’s bonus calculation. A total of 281 students and professionals participated in this experiment. Their responses were examined using regression analysis.
Findings
Our results indicate that individuals mostly prefer the percentages presentation format and that the use of the percentages presentation format, a lower level of task complexity, and a better understanding of the variance presentation format lead to more accurate calculations in the experimental task.
Research implications
Our study provides a call for further research on factors that influence the choice of presentation format as a potentially fruitful area for management accounting researchers.
Practical implications
We exhort practicing management accountants to exert direct influence on employees’ decision making through the use of variance presentation formats that fit their tasks and promote understanding.
Originality/value
Our experiment introduced two major innovations: it uses an interactive data visualization approach allowing subjects to select their preferred presentation format; and it focuses on production variances, a topic that has received less attention in the academic managerial accounting literature, but is still very relevant to practitioners.

Abstract
Purpose
The purpose of this paper is to identify and discuss the web-marketing behavioural models adopted in the wine industry using as case studies several leading Italian wineries. It aims to propose a new methodology to evaluate the impact of web marketing strategies on online brand visibility and image.
Design/methodology/approach
The paper is based on literature review and case study approach. The study uses six leading Italian wineries as case studies, selected by taking into account six strategic profiles: business size, business management, corporate brand reputation, competitive strategy, marketing orientation and marketing budget.
Findings
The proposed structured methodology highlights new key elements that could be implemented in a marketing plan. The research results propose a conceptual three-dimension approach that integrates a business's strategic orientation with its digital-marketing strategy and its social media tactics. It also includes specific evaluation criteria to measure the impact on the business's strategic objectives.
Research limitations/implications
The applied research approach should be extended to other business typologies and wine-producing countries to allow the generalisation of results. In addition, the monitoring period should be extended to confirm the reliability of results.
Originality/value
The applied methodology can be adopted more broadly, and it underlines managerial implications that can be extended to the rest of the Italian wine industry, as well as to the parts of the wine sector that are dominated by the presence of SMEs.

Abstract
There has been limited study to date of the effectiveness of alternative methods of presenting accounting information for financial decision purposes. Explores the relative usefulness of the schematic face, compared with conventional presentation formats, for communicating the multivariate information set conveyed in a set of financial statements. Compares the ability of accounting statement users of different levels of sophistication to “predict” bankruptcy and financial health of companies on the basis of cartoon faces, accounting statements and financial ratios. Presents evidence that the schematic representations are processed more quickly than either of the more traditional methods of information presentation, and with no loss of accuracy, by all three different types of user examined. Concludes by arguing the potential generalizability of the cartoon graphic approach to more complex financial decision applications, such as those in banking and financial analysis.

Abstract
Decision‐making in executive information systems (EIS) frequently involves scanning complex sets of multidimensional data, which can be difficult with traditional data portrayal techniques. Therefore, schematic faces may be useful in EIS. Schematic faces can represent up to 20 variables by mapping those variables to the salient facial features so that positive outcomes result in a happier looking face, thus simplifying the data scanning process. The composites of the variables, i.e. the faces, aid management by providing a sophisticated graphical interface between the data and the decision maker. An experiment was conducted to compare decision time and accuracy when basing decisions on tables, bar charts, and schematic faces. The gender and cognitive style of subjects were also considered. MANOVA results indicate that both decision speed and accuracy are better when viewing schematic faces. Cognitive style was also a significant factor in the model.

Abstract
Accounting information is essentially multivariate and the relationships among variables may be difficult to establish. Differing multivariate information presentation methods may impact on the quality of the decisions made by users. Existing studies in this area have given scant attention to differences between individual users, despite earlier suggestions from the second author of this paper that both gender and personality might impact on information processing. This study focuses on the interaction of the decision maker (addressing issues of gender, personality, cognitive style and ability) with the data presentation method (including tables, graphical and pictorial methods) in the management decision making process. The paper reports on experiments conducted with respondents of varying degrees of accounting sophistication, using a failed/non‐failed decision environment. Results provide support for the use of graphical and pictorial methods as means of representing data for this decision task, while also identifying the influence of gender, spatial ability and tolerance of ambiguity. These findings have implications for the matching of information presentation with the characteristics of the decision maker in management decision making.
