An analysis of review content and reviewer variables that contribute to review helpfulness     

MSI Malik  Ayyaz Hussain 《Information processing & management》2018,54(1):88-104

Review helpfulness is attracting increasing attention of practitioners and academics. It helps in reducing risks and uncertainty faced by users in online shopping. This study examines uninvestigated variables by looking at not only the review characteristics but also important indicators of reviewers. Several significant review content and two reviewer variables are proposed and an effective review helpfulness prediction model is built using stochastic gradient boosting learning method. This study derived a mechanism to extract novel review content variables from review text. Six popular machine learning models and three real-life Amazon review data sets are used for analysis. Our results are robust to several product categories and along three Amazon review data sets. The results show that review content variables deliver the best performance as compared to the reviewer and state-of-the-art baseline as a standalone model. This study finds that reviewer helpfulness per day and syllables in review text strongly relates to review helpfulness. Moreover, the number of space, aux verb, drives words in review text and productivity score of a reviewer are also effective predictors of review helpfulness. The findings will help customers to write better reviews, help retailers to manage their websites intelligently and aid customers in their product purchasing decisions.  相似文献

Reactivity without legitimacy? Online consumer reviews in the restaurant industry     

Jean-Samuel Beuscart  Kevin Mellet 《Journal of Cultural Economy》2016,9(5):458-475

In recent years, web sites where individual consumers can rate and review goods and services have mushroomed all over the Internet. Restaurants are particularly affected by online reviewing. If the impact of online consumer reviews (OCRs) on the demand side of markets is now well understood and measured, few studies examine the reception of this new evaluation method by those who are assessed. Based on interviews with French restaurant managers, our research shows that OCRs systems reconfigure relations of accountability in the restaurant industry. We use the notion of reactivity to describe the mechanisms through which the new evaluation system transforms the activity of restaurants. We also examine the affects surrounding the reception of ratings and reviews by restaurant managers and the moral criteria that accompany their discourses on online reviews. Many restaurants consider online reviews as a brutal and hypocritical mode of judgment. The judgment produced by online ratings and reviews is not easily borne by restaurant managers, because it challenges the conventions of quality they had previously internalized as legitimate, that is, those produced by professional experts. We interpret this ambivalent reception as the unfinished movement of transforming a performative reputation device into a legitimate evaluation institution.  相似文献   

School monitoring and quality assurance in the New Zealand school system   总被引：1，自引：0，他引：1  

Fubuki Sakura 《Educational Research for Policy and Practice》2007,6(3):229-234

This article reports on the New Zealand education quality assurance and school monitoring system, including its framework, and responsibilities of agencies. It first gives an outline of the education system in New Zealand, and then introduces the role of school charters and levels of schooling. To ensure the quality of schools, the methods of school self-review and external reviews of schools are used by the New Zealand government. Schools are given a list of obligations that they have to follow. Assessment policies and the school curriculum are designed to support learning. Fubuki Sakura formerly called William Leung  相似文献   

Person-centred reviews and transition: an exploration of the views of students and their parents/carers     

Julie White  Tina Rae 《Educational Psychology in Practice》2016,32(1):38-53

The person-centred review (PCR) is a model for the review of a student’s special educational needs (SEN) which places the young person and their family at the centre of the process. This mixed-methods, exploratory study investigated the views of 16 students with SEN aged between 10–11 years (Year 6) and 13–14 years (Year 9), and their parents/carers on their PCRs (which were mostly held at transition). Attention was paid to potential changes in the young people’s locus of control and feelings towards school. Findings indicated that the PCR is a collaborative, constructive and reassuring process for families where a wealth of information is shared openly and honestly within a relaxed, yet structured, meeting. The young people were generally positive about the process, although many felt daunted beforehand. Some parents felt the meeting was too long and not entirely accessible to children. The study did not conclude that the young people’s locus of control or feelings towards their education changed following the PCR. Implications for good practice are discussed, particularly for educational psychologists and in the context of the SEN and Disability Code of Practice.  相似文献

Cloud-based big data analytics for customer insight-driven design innovation in SMEs     

《International Journal of Information Management》2020

Fast development of IT and ICT facilitate customers to post a large volume of their concerns and expectation online, which are widely accepted to be a valuable resource for product designers. However, it is found that only a small number of small and medium-sized enterprises (SMEs) have capabilities to leverage customer online insights for design innovation, which often demonstrate a significant share in national economies growth. To discover the beneath reasons regarding the barrier that prevent them to make effective utilization, in this study, as a concrete example, manufacturing SMEs in the South Wales and Greater Manchester industrial areas of the UK are focused and their potential motivations for using and knowledge of big data-based customer analytics are investigated. An exploratory survey was conducted in terms of the type of customer data they have, the storage approaches, the volume of customer data, etc. Next, a carefully devised exploratory study was undertaken to understand how SMEs perceive the relations between customer data and product design, how about their expectations from big customer data analytics and what really challenges SMEs to exploit the value of big customer data. Besides, a demonstration platform is developed to present SMEs an automatic process of analysing customer online reviews and the capacity on customer insights acquisition and strategic decision making. Finally, findings from two focus groups indicate the different managerial and technical considerations required for SMEs considering implementing big data and customer analytics. This study encourages SMEs to welcome big customer data and suggests that a cloud-based approach may be the most appropriate way of giving access to big data analytics techniques.  相似文献   

Improving aspect extraction by augmenting a frequency-based method with web-based similarity measures     

Shi Li  Lina Zhou  Yijun Li 《Information processing & management》2015

Online review mining has been used to help manufacturers and service providers improve their products and services, and to provide valuable support for consumer decision making. Product aspect extraction is fundamental to online review mining. This research is aimed to improve the performance of aspect extraction from online consumer reviews. To this end, we augment a frequency-based extraction method with PMI-IR, which utilizes web search in measuring the semantic similarity between aspect candidates and target entities. In addition, we extend RCut, an algorithm originally developed for text classification, to learn the threshold for selecting candidate aspects. Experiment results with Chinese online reviews show that our proposed method not only outperforms the state of the art frequency-based method for aspect extraction but also generalizes across different product domains and various data sizes.  相似文献
