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   

Recording the war effort: immigrant communities in Latin America and the memory of the Great War     

María Inés Tato 《档案与原稿》2020,48(2):200-215

ABSTRACT

This paper aims to analyse the initiatives undertaken by some immigrant communities residing in Latin America to record their mobilisation around the First World War. After the armistice, European communities in Argentina, Bolivia, Brazil, Chile, Mexico, Paraguay, Peru, Uruguay and other countries gathered detailed information about their activities during the conflict, published as profusely illustrated books of remembrance, offered to their governments as proof of their loyalty. The article intends to establish the peculiar nature of these publications as records of the war effort, and analyse the agents and processes of their elaboration, and their role as commemorative but also as archival documents.  相似文献

乾隆版《曲阜县志·类编·著述》,是汇集历代邑人著述的综合性书目 ,所收之书分类部居 ,并撰有部序、类序 ,指明授受源流。每书除著录书名、作者、卷数等基本事项 ,有的还注有官职、考注。是方志书目中比较好的一种。但其中问题也不少 ,如张冠李戴、归类不当、体例不纯、遗漏严重等 ,极大的影响了该书目的参考价值。  相似文献   

A Model of Translations     

Chr. Hjorth-Andersen 《Journal of Cultural Economics》2001,25(3):203-217

This paper attempts to model translations from one language intoanother. Book markets are an integral part of the cultural life of anation, and new ideas on political, social and cultural aspects arespread by means of books. It is a fact, however, that linguisticbarriers will often prevent a book from reaching a mass audience unlessit is translated. But the mechanism involved in translations has notbeen adequately described. A model is presented here in three steps: Thefirst step is to determine the number of new books in an economy. Thenext step is to determine the propensity to import translated works fromother countries. The final step is to determine from which language thetranslation will originate. This provides a basis for judging thecultural affinity between nations.  相似文献

史书多维知识重组与可视化研究——以《史记》为对象     

张琪  王东波  黄水清  邓三鸿 《情报学报》2022,41(2):130-141

艰涩的古汉语文法和线性的内容呈现方式是普通读者从史籍原文获取所需信息的两大障碍。该问题的解决需要实现史书知识重组与形式再造,即支持从时间、人物、地点等多个维度出发获取史书中的知识,并以图结构的方式呈现所返回的结构化知识以及对应的史书原文,从而在降低相关信息的获取与理解难度的同时,拉近读者与史籍原文的距离。然而,目前基于史书原文获取结构化知识的研究较少,已有研究自动化程度较低,且多在可视化呈现上与史书原文相割裂。因此,本研究提出并实现了史书多维知识重组与可视化系统,该系统包括史书多维知识建模、基于古籍智能处理技术的史书多维知识库自动构建与多维知识可视化三部分。最终将该系统应用于我国第一部纪传体史书《史记》,实现了其以人物、时间、地点、社会集团、职官等不同维度为中心的自动重组与可视化。  相似文献
