Abstract

Purpose

Recently, the importance and effectiveness of Wikipedia Mining has been shown in several researches. One popular research area on Wikipedia Mining focuses on semantic relatedness measurement, and research in this area has shown that Wikipedia can be used for semantic relatedness measurement. However, previous methods are facing two problems; accuracy and scalability. To solve these problems, the purpose of this paper is to propose an efficient semantic relatedness measurement method that leverages global statistical information of Wikipedia. Furthermore, a new test collection is constructed based on Wikipedia concepts for evaluating semantic relatedness measurement methods.

Design/methodology/approach

The authors' approach leverages global statistical information of the whole Wikipedia to compute semantic relatedness among concepts (disambiguated terms) by analyzing co‐occurrences of link pairs in all Wikipedia articles. In Wikipedia, an article represents a concept and a link to another article represents a semantic relation between these two concepts. Thus, the co‐occurrence of a link pair indicates the relatedness of a concept pair. Furthermore, the authors propose an integration method with tfidf as an improved method to additionally leverage local information in an article. Besides, for constructing a new test collection, the authors select a large number of concepts from Wikipedia. The relatedness of these concepts is judged by human test subjects.

Findings

An experiment was conducted for evaluating calculation cost and accuracy of each method. The experimental results show that the calculation cost of this approach is very low compared to one of the previous methods and more accurate than all previous methods for computing semantic relatedness.

Originality/value

This is the first proposal of co‐occurrence analysis of Wikipedia links for semantic relatedness measurement. The authors show that this approach is effective to measure semantic relatedness among concepts regarding calculation cost and accuracy. The findings may be useful to researchers who are interested in knowledge extraction, as well as ontology researches.

Abstract

This chapter examines the impact of price fluctuations in foreign stock markets on the stock prices of domestic banks in Korea, Malaysia, Singapore, and Thailand. Some studies have argued that the 2007–2009 global financial crisis (GFC) affected domestic banks less in East Asia, even though the supporting evidence is rather limited. Employing a multinomial logit model, we estimate how changes in the United States and Japanese stock markets affected the banking sectors in the sampled countries before the 1997 Asian financial crisis, and before and during the more recent GFC. We interpret the number of banks in a given country that experienced a large price shock on the same day (or “coexceedance”) as shocks to the domestic banking sector. The results suggest that fluctuations in foreign stock market indices exerted a larger impact on the prices of East Asian banking stocks during the 2000s than during the 1990s. In addition, although the shocks brought about by the deterioration of foreign stock markets were significant before the GFC, both increases and decreases in foreign stock prices significantly affected the banking sectors of the respective countries during the crisis. Lastly, we conclude that increasing foreign capital flows and foreign assets and liabilities greatly influenced domestic banking systems in East Asia during the 2000s.

Abstract

Purpose

Using a recent rural farm household survey, the purpose of this paper is to investigate inclusiveness and effectiveness of agricultural cooperatives in Ethiopia.

Design/methodology/approach

The study employs a logit model to examine inclusiveness and an endogenous switching regression (ESR) model to evaluate the effectiveness of agricultural cooperatives.

Findings

The results show that agricultural cooperatives are less inclusive of land-poor and illiterate households. On the other hand, the estimated results indicate that cooperatives effectively improved agricultural performance and welfare of its member households – i.e. membership in cooperatives increases yield and income by 1.37 quintal/hectare and 1,804 birr, respectively. Moreover, the result shows that marketing cooperatives effectively increased marketed surplus of their members by 34 percent.

Research limitations/implications

The study has important implications regarding the ways to improve the effectiveness and/or inclusiveness of agricultural cooperatives.

Originality/value

While accounting for the collective behavior of cooperatives, this study uses multiple outcome variables in examining the effectiveness of cooperatives in Ethiopia. Furthermore, this paper employs the ESR model and accounts for potential problems in estimating impact using non-experimental data.

Abstract

In late 2019, Dr. Hiroaki Kitano, the president and director of research at Sony Computer Science Laboratories (Sony CSL), had decided he would be stepping down from his position soon. Sony CSL, a small blue-sky fundamental research facility funded by Sony, had always operated on the strength of the trust between Sony's CEO and the lab's director. Sony had been hands-off in its management, leaving Kitano to hire, fire, fund, and evaluate the lab's researchers and project portfolio at his own discretion. Now that he was stepping down, however, he worried that Sony CSL could not withstand his departure. Kitano wanted to make a transparent plan for the organization's future before he handed off Sony CSL to his successor. That plan involved three key decisions. First, what should be the optimal structure and governance of Sony CSL? Should it maintain its independence and autonomy, or should it align more closely with Sony's business priorities? Second, how could Sony CSL scale its impact on Sony and society at large, given its small size? Finally, should Sony CSL establish some standard methods of measuring project success and strength of the portfolio? In making these decisions, Kitano wanted to ensure that he preserved the unique culture that had allowed Sony CSL to pursue path-breaking research and innovation.

Abstract

Purpose

Service robotics, a branch of robotics that entails the development of robots able to assist humans in their environment, is of growing interest in the hospitality industry. Designing effective autonomous service robots, however, requires an understanding of Human–Robot Interaction (HRI), a relatively young discipline dedicated to understanding, designing, and evaluating robotic systems for use by or with humans. HRI has not yet received sufficient attention in hospitality robotic design, much like Human–Computer Interaction (HCI) in property management system design in the 1980s. This article proposes a set of introductory HRI guidelines with implementation standards for autonomous hospitality service robots.

Design/methodology/approach

A set of key user-centered HRI guidelines for hospitality service robots were extracted from 52 research articles. These are organized into service performance categories to provide more context for their application in hospitality settings.

Findings

Based on an extensive literature review, this article presents some HRI guidelines that may drive higher levels of acceptance of service robots in customer-facing situations. Deriving meaningful HRI guidelines requires an understanding of how customers evaluate service interactions with humans in hospitality settings and to what degree those will differ with service robots.

Originality/value

Robots are challenging assumptions on how hospitality businesses operate. They are being increasingly deployed by hotels and restaurants to boost productivity and maintain service levels. Effective HRI guidelines incorporate user requirements and expectations in the design specifications. Compilation of such information for designers of hospitality service robots will offer a clearer roadmap for them to follow.

Abstract

Japan is home to a relatively conservative and group-oriented culture in which social expectations can exert powerful pressure to conform to traditional patterns of behaviour. This includes gender norms, which have long been based around the common stereotypes of men as breadwinners and women as housewives. Social liberalisation and economic change in the late 20th century saw these patterns change as more women entered the workforce and, despite Japan's dismal standing in global equality rankings, began to make inroads into some positions of political and corporate leadership. Yet, the way in which women are treated by men is shaped not only by female gender norms but also by the social factors that determine male patterns of behaviour. This chapter considers how Japan's male gender norms, particularly the focus on man as economic labourers rather than active members of the family unit, have damaged many men's ability to connect, on an emotional level, with the women in their lives. It looks at the issue of misogyny; what is known as the Lolita Complex; the growing trend of herbivore men; and the concept of Ikumen, men who are active within the family. While some of these patterns of behaviour can be harmful – for women on the individual level, and for Japan as a whole, on the social level – there are some trends which suggest that gender norms in Japan can be directed in a manner which will allow for much healthier emotional relationships to develop between the genders in a manner that will help build a society that is more cognisant of and attentive to the needs of women.
