基于兼容性感知的服务推荐方法研究

随着互联网的发展,信息爆炸的问题日益突出,开发者很难准确地找到自己需要的服务。服务推荐技术可以帮助开发者过滤信息,提供个性化的推荐,节省开发者的时间和精力。现有的Web服务推荐系统通常更注重Web服务推荐的准确性,而忽略了Web服务之间的兼容性。这可能导致在创建应用程序时出现服务之间不兼容的情况。为了解决上述挑战,本文提出了一种基于兼容性感知的服务推荐方法(SRCR)。首先,SRCR使用图神经网络算法来对历史记录进行深入挖掘,提取应用程序和服务的历史记录特征,从而计算其偏好。其次,SRCR通过对历史服务共同调用情况进行分析,预测候选服务和现有服务的兼容性。最后,将上述二者相融合得到最终的服务列表。在ProgrammableWeb上收集的真实数据集上进行的大量实验证明了我们所提出的SRCR方法的有效性。With the development of the Internet, the problem of information explosion has become increasingly prominent. Developers find it difficult to accurately find the services they need. Service recommendation technology can help developers filter information, provide personalized recommendations, and save developers time and energy. The existing Web service recommendation systems usually focus more on the accuracy of Web service recommendations, while ignoring the compatibility between Web services. This may lead to incompatibility between services when creating applications. To address the aforementioned challenge, this paper proposes a Service Recommendation method based on Compatibility Awareness (SRCR). Firstly, SRCR employs graph neural network algorithm to deeply mine historical records, extract historical record features of applications and services, and calculate the preferences of applications. Secondly, SRCR predicts the compatibility between candidate services and existing services by analyzing the joint invocation of historical services. Finally, the above two are combined to obtain the final service list. A large number of experiments conducted on real datasets collected on ProgrammableWeb have demonstrated the effectiveness of our proposed SRCR method.

中国品牌全球化与文化兼容性对海外发达市场消费者品牌效用评价的影响——基于对日韩消费者调查的实证研究

探讨中国品牌全球化战略实施的优化路径对于推动高水平对外开放、提升品牌对经济发展的引领作用具有重要意义。基于对日本和韩国消费者的调查数据,采用分层结构方程模型(MG-SEM)和模糊集定性比较分析法(fsQCA)检验发现:提高发达市场消费者的中国品牌全球化感知和品牌文化兼容性感知有利于提升消费者的品牌效用评价;消费者的品牌知名度感知、品牌质量感知和品牌社会影响力感知起到了差异化的中介作用。鉴于此,中国品牌在海外寻求扩张时,应注重打造全球形象,建设兼容性品牌文化,基于目标市场消费者需求差异夯实品牌资产,进而提升消费者中国品牌效用评价。
