A network-based concept extraction for managing customer requests in a social media care context     

《International Journal of Information Management》2020

Web 2.0 changed everyday life in many aspects, including the whole system that orbits around the purchase of products and services. This revolution necessarily involved also companies, because customers became increasingly demanding. The diffusion of social media platforms pushed customers to prefer this channel for quickly obtaining information and feedback about what they want to buy, as well as for asking help after the selling. In this framework, many organisations adopted a new way of providing assistance known as social customer care. A direct link to companies allows customers to obtain real-time solutions. In this paper, we introduce a new strategy for automatically managing the information listed in the requests that customers send to the social media accounts of companies. Our proposal relies on the use of network techniques for extracting high-level structures from texts, highlighting the different concepts expressed into the customers’ written requests. The texts can be then organised on the basis of this new emerging information. An application to the requests sent to the AppleSupport service on Twitter shows the effectiveness of the strategy.  相似文献   

Exploring CO2 mitigation pathway of local industries using a regional-based system dynamics model     

《International Journal of Information Management》2020

Low-carbon development based on low energy consumption, low pollution and low emissions has become an important strategic choice for worldwide governments to achieve sustainable development. In order to support smart government in decision making, information systems have been developed to monitor and predict CO₂ emissions. Most of the existing studies investigate CO₂ emission amounts, identify influencing factors of CO₂ emission and discuss potential suggestions to mitigate CO₂ emission for different industries. They often focus on CO₂ emission research of industries in a region or country, while the integration of carbon flow in the neighboring regions is not well studied. Therefore, this paper proposes a system dynamics model to explore an optimal carbon emission reduction path of a regional industry by integrating regional differences, i.e., industrial comparative advantages, technology advantages and the inter-regional context between the neighboring regions. In the case study, we use a key industry in a typical industrial region of Western China, the cement industry in Chongqing, as a scenario to simulate the CO₂ emission, possible energy demand and cement production of the cement industry in this region for recent years. Simulation results show that by leveraging the regional differences, especially the collaboration of the industrial chain and production capacity among regions, the cement industry in Chongqing can achieve the low-carbon target. In addition, through the analysis and discussions about the features of our model and Chongqing’s cement industry, it reflects that our model using regional differences is applicable to industries with a common demand market at the regional level such as energy, chemical and steel industries.  相似文献

微博预置话题与突发话题的特征挖掘研究     

何跃  王欣瑞  韩玫  肖敏 《情报探索》2020,(4):50-57

[目的/意义]借鉴拉斯韦尔5W传播模型,探讨微博中预置话题与突发话题的特征。[方法/过程]基于因子分析的关键节点影响力评价方法来研究话题节点特征;利用Ward方法对话题博文量曲线进行聚类,并对曲线进行多项式拟合;对话题情感度曲线进行聚类,并对不同类型话题的峰度和整体情感加权平均高峰期进行研究。[结果/结论]话题首节点多是信息分享,其中突发话题的传播多是从事件的客观描述开始;话题微博按博文量可分为前热型、中热型、后热型、爆发型和持续型,其中突发话题比预置话题爆发得更早、持续时间更长;话题出现72小时后公众情感趋于中立,但突发话题情感曲线高峰期比预置话题更集中,整体情感加权平均高峰期更早出现,曲线趋势更复杂。  相似文献   

人为排放水汽对北京地区雾霾天气的影响分析     

李崇兴  赵荣  王海东 《科学与管理》2020,40(2):67-77

根据国家气象局中国天气网站公布的北京和河北部分城市整点天气实况以及环保部公布的空气质量指数等资料分析了北京地区空气含水量的本底值和雾霾气候条件下的增量。结果表明,采暖季节,人为释放的水气量导致北京地区空气含水量产生较大幅度的增加,对北京地区的雾霾天气加重起着不可忽视的作用。经过对2016年12月和2017年12月两次雾霾天气过程的分析,发现其平均空气含水量高出本底值0.78g/m3,北京城区站2017年12月29日0~7时空气含水量增幅为24.4%。  相似文献
