However, content-sharing platforms face copyright infringement issues related to content theft and platform invasion, dampening the flow of traffic to e-commerce. Traditional copyright protection methods lack effectiveness and efficiency, which can be solved by Non-Fungible Tokens (NFTs) stored on a blockchain. This study examines how a content-sharing platform adopts three NFT-based copyright protection strategies: the NFT-based copyright certification strategy to combat content theft, the NFT-based content moderation, and copyrighted material provision strategies to combat platform invasion. Our paper models a two-sided platform with content consumers and suppliers. Platform invasion occurs when suppliers bring copyright-infringing content to the platform, while content theft refers to content suppliers being pirated outside the platform. We identify the optimal combination of platform copyright protection strategies. The platform may adopt the copyright certification strategy to combat content theft. However, we show that the platform cannot benefit from adopting both content moderation and material provision strategies to counter platform invasion if the quantity of infringing materials used by infringers is small and the material provisioning costs of the platform are low. Moreover, there are mutually enhancing effects between content moderation and material provision strategies. Our study emphasizes the importance of NFT-based copyright protection strategies to content-sharing platforms and provides a comprehensive framework for understanding the implications of copyright certification, content moderation, and copyrighted material provision.</div></div>","PeriodicalId":50541,"journal":{"name":"Electronic Commerce Research and Applications","volume":"71 ","pages":"Article 101506"},"PeriodicalIF":5.9,"publicationDate":"2025-05-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144069200","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Scenario I defines a simple cooperative channel consisting of one manufacturer and one retailer. In Scenario II, we consider a more general setting where there is an independent retailer who competes with the Manufacturer-Retailer alliance in Scenario I. We propose a novel cooperative advertising optimization model, wherein a manufacturer can advertise product directly through SEA campaigns and indirectly by subsidizing its retailer. To highlight the distinctive features of SEA, our model incorporates dynamic quality scores and focuses on a finite time horizon. In each scenario, we provide a feasible equilibrium solution of optimal policies for all members. Subsequently, we conduct numerical experiments to perform sensitivity analysis for both the quality score and gross margin. Additionally, we explore the impact of the initial market share of the competing retailer in Scenario II. Finally, we investigate how retail competition affects the cooperative alliance’s optimal strategy and channel performance.

While previous AI-based approaches primarily targeted COVID-19 severe pneumonia and sought to enhance machine learning accuracy, they often neglected critical aspects such as distinguishing diagnostic and prognostic features among COVID-19 infectious, non-COVID infectious, and non-infectious severe pneumonia, as well as the explainability and fairness of user-centric AI assist decisions. This study es the need for robust, fair, and reliable diagnosis and prognosis of severe pneumonia within the context of the COVID-19 pandemic. This paper introduces a user-centric framework that first employs a GaussianCopula-based data augmentation method to enhance fairness by addressing small imbalanced sample sets. Following this, the framework introduces an explainable AI system designed to classify three types of severe pneumonia using demographic and physiological indicators, offering transparent decision-making processes and an understandable analysis of prognosis risk factors. Our fair system utilizes transparent models exclusively, which enables healthcare practitioners to access intelligent and reliable medical services such as pre-diagnosis and prognosis analysis (the likelihood of death) of severe pneumonia. The results show the data augmentation method efficiently reduces data bias and enhances fairness, reaching 70.70% distribution similarity. Our transparent model-based severe pneumonia classification module achieves 98.88% F1-scores on a real-world dataset. The transparent mechanism reveals that the four most significant features for classifying severe pneumonia types are ‘Interleukin_6’, ‘Albumin’, ‘D_Dimer’, and ‘CD4_absolute_count’. Meanwhile, the explainable statistical analysis identifies critical mortality risk factors for each pneumonia category: ‘Blood platelet’ and ‘Creatinine’ for COVID-19 severe pneumonia, ‘Hemameba’, ‘Interleukin-6’, and ‘Uric Acid’ for non-COVID-19 infectious severe pneumonia, and ‘Hemameba’, ‘BNP’, ‘Cholesterol’, and ‘PT’ for non-infectious severe pneumonia. Our study highlights the potential of transparent machine learning algorithms for accurate diagnosis and Cox proportional regression for transparent risk trend prediction. These analytical tools and medical results can facilitate early and appropriate management of pneumonia patients for doctors, potentially revolutionizing diagnostic processes and patient care strategies to improve clinical outcomes.</div></div>","PeriodicalId":50541,"journal":{"name":"Electronic Commerce Research and Applications","volume":"71 ","pages":"Article 101499"},"PeriodicalIF":5.9,"publicationDate":"2025-04-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143816268","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"管理学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A novel variant, self-livestreaming, is gaining traction. When manufacturers conduct multiple self-livestreaming events across different platforms, each livestreaming room or streamer resonates differently with consumers. In this context, two distinct consumer segments emerge: loyal consumers and regular consumers. This study examines the dual self-livestreaming strategy adopted by manufacturers, incorporating factors including room attractiveness and consumer types to determine the optimal pricing and sequencing for three distinct livestreaming strategies: S (simultaneous livestreaming in both rooms), L (the low-attractiveness room livestreams first), and H (the high-attractiveness room livestreams first). The results reveal that a lower proportion of loyal consumers or higher room attractiveness leads to greater profits for manufacturers. Moreover, the choice of livestreaming strategy for manufacturers varies based on room attractiveness and the proportions of the two consumer types. In the extended model, we analyze the impact of operational costs on the decision to use one or two rooms, particularly when the low-attractiveness room has no loyal consumers. Specifically, we explore how room attractiveness and the proportion of regular consumers influence room adoption decisions.

Recent studies have leveraged contrastive learning as an auxiliary task to enhance sequence representations, with the goal of improving recommendation accuracy. However, an important challenge arises: random item masking, a key component of contrastive learning, while promoting robust representations through intricate semantic inference, may inadvertently distort the original sequence semantics to some extent. In contrast, methods that prioritize the preservation of sequence semantics tend to neglect the essential masking mechanism for robust representation learning. To address this issue, we propose a model called <strong>C</strong>ontrastive <strong>L</strong>earning with <strong>A</strong>dversarial <strong>M</strong>asking (CLAM) for sequential recommendation. CLAM consists of three core components: an inference module, an occlusion module, and a multi-task learning paradigm. During training, the occlusion module is optimized to perturb the inference module in both recommendation generation and contrastive learning tasks by adaptively generating item embedding masks. This adversarial training framework enables CLAM to balance sequential pattern preservation with the acquisition of robust representations in the inference module for recommendation tasks. Our extensive experiments on four benchmark datasets demonstrate the effectiveness of CLAM.
