Abstract

Conflictual returns generate a considerable amount of operational cost in the e-commerce world. Conflictual returns occur in a marketplace when a customer returns a product for certain reasons (broken, missing products, etc.), the seller does not accept the return, and the case becomes unresolved. In the case of conflictual returns, Trendyol needs to resolve the issue as the mediator platform. The decision is made by operators inspecting the customer, the seller, and the case. This process consumes lots of time and human resources. This study aims to automate the resolution of conflictual returns by developing machine learning models based on Logistic Regression (LogReg), CatBoost, and LightGBM. The desired outcome of the study is to make the same decisions on the conflictual returns as the operators as much as possible. The success of the classification models has been evaluated by using the precision, recall, and the area under the curve (AUC)-score metrics. The results show that the proposed LightGBM-based model exhibits the best performance in distinguishing the conflictual returns. The automation of this process will be of great benefit in terms of operational efficiency.
