Human agents are increasingly being replaced by chatbots. However, like humans, chatbots can also make mistakes in service delivery by failing to provide accurate answers to customer questions while research on service recovery has been highly focused on human employees. Recognizing the necessity of research on effective chatbot service recovery strategies, this study investigated the relationships among service recovery messages (courteous apology vs. humorous apology), perceived sincerity, recovery satisfaction, and continuous usage intention. An online experiment was conducted with the participants randomly assigned to one of two experimental conditions (courteous apology vs. humorous apology). After using the chatbot developed for this study, the participants completed a questionnaire. The analysis results revealed that, in comparison to the humorous apology, the courteous apology had a higher positive predictive effect on perceived sincerity, Furthermore, perceived sincerity and recovery satisfaction sequentially mediated the relationship between the chatbot's courteous apology and continuous usage intention. In conclusion, this study demonstrates that the courteous apology was a more effective approach as a chatbot service recovery strategy. This study offers insights into crafting recovery service messages for chatbots.

In the Structural Health Monitoring (SHM) system of civil engineering, data missing inevitably occurs during the data acquisition and transmission process, which brings great difficulties to data analysis and poses challenges to structural health monitoring. In this paper, Convolution Neural Network (CNN) is used to recover the nonstationary wind speed data missing randomly at sampling points. Given the technical constraints and financial implications, field monitoring data samples are often insufficient to train a deep learning model for the task at hand. Thus, simulation combined transfer learning strategy is proposed to address issues of overfitting and instability of the deep learning model caused by the paucity of training samples. According to a portion of target data samples, a substantial quantity of simulated data consistent with the characteristics of target data can be obtained by nonstationary wind-field simulation and are subsequently deployed for training an auxiliary CNN model. Afterwards, parameters of the pretrained auxiliary model are transferred to the target model as initial parameters, greatly enhancing training efficiency for the target task. Simulation synergy strategy effectively promotes the accuracy and stability of the target model to a great extent. Finally, the structural dynamic response analysis verifies the efficiency of the simulation synergy strategy.

In recent, keeping and developing relationships with current customers is a key service business goal, and service recovery efforts is to be the essence of service business strategy. But many researchers have neglected to focus on that issue. So this research is intended to explore service quality factors that include service recovery efforts and grip those difference among service operations systems. Service operations systems are divided into three categories. Our study results suggest that customer oriented firms need to develop a comprehensive service recovery system and must include service recovery as a service quality factor.

The purpose of this study was to examine the effect of perceived justice associated with service recovery on perceived service quality, and the relationships among perceived service quality, customer satisfaction and behavioral intentions in online apparel shopping contexts. Justice theory provided the theoretical framework for this study. The research strategy employed an online survey methodology. Online shoppers (N=669) who had experiences in service failure and dissatisfactions completed a questionnaire. The model of the study was tested by structural equation modeling (SEM) and the results of SEM revealed positive effect of perceived justice regarding service recovery on perceived service quality, positive effect of perceived service quality on customer satisfaction, and positive effect of customer satisfaction on behavioral intention. The results of this study have implications for online retailers. Online retailers need to understand the importance of service recovery by which service failures are managed.

The purpose of this study is to prove that the appropriate fit between service failure and recovery strategy can efficiently maximize customer satisfaction and behavioral intention, by using the prepared scenario through comprehensive approach concerning how the expectation level of service recovery has influence on perceived fairness, satisfaction and behavioral intention of service recovery based upon size in case of service failure. This study has been conducted by way of selection of filling-up type questionnaires for customers themselves who have experience in service failure out of customers who can easily visit family and hotel restaurants, that is, domestic restaurants in Seoul area, $June{\sim}August$ 2004, by setting factorial design of 2(control, severeness)$\times$3(distributive fairness, procedural fairness, mutual relational fairness)$\times$2(customer satisfaction, customer behavior). The survey was performed on the customers who visited common restaurants, family restaurants, hotel restaurants, etc. mainly in Seoul, and total 600 sheets of questionnaires were distributed and 496 sheets of them were returned(82.67% of return ratio). Research findings are as follows; First, perceived recovery justice has an effect on customer satisfaction and behavioral intention. Second, customer satisfaction and restaurant satisfaction have positive influence on behavioral intention. The results will be helpful for them to develop a further service failure and recovery framework. For service marketing managers, the results will suggest specific guidelines for establishing service recovery strategies.

The purpose of this study was to analyze the effect of justice (distributive, interactional, and procedural) perception of e-service recovery in restaurant businesses on e-service recovery satisfaction, negative word of mouth, trust, and commitment. We designed a quasi-experimental study using eight different scenarios of justice application. One of the eight scenarios was distributed to each respondent to read, and the respondent then answered regarding feelings and subsequent action. Data analysis was based on 232 usable responses. The results imply that interactional justice is more important than other forms of justices in e-service recovery of restaurant businesses, indicating that restaurants must approve the service failure, make an apology to the customer, and maintain a courteous attitude at all times. In addison, the restaurant has to consider an e-service recovery program as a long-term strategy because the effect of e-service recovery in restaurant businesses grows slowly and takes time-consuming effort.

Service failures are fairly common these days, and recovering from them is difficult. If service failures are not addressed quickly, the service provider may lose revenue and customers. A good service recovery strategy will positively impact the business results of the service provider. The study aims to demonstrate the impact of service recovery on the satisfaction and word of mouth of international visitors towards homestays in the Mekong Delta, Vietnam. The research data was collected from 320 international visitors who have used services at homestays and experienced service failures in the Mekong Delta, Vietnam. Structural equation modeling was applied to analyze the data. The result shows that 3 dimensions constitute service recovery which are distributive justice, interactional justice, and procedural justice. Most importantly, the study has proved the positive impact of service recovery on both satisfaction and word of mouth of overseas tourists towards homestays in the Mekong Delta, Vietnam. The results have stressed the importance of service recovery to tourists' perceptions of service quality and service image. In addition to this, the study suggests that homestay owners should develop risk handling and risk prevention plans for their services.
