摘要
随着互联网技术的迅猛发展，大数据已成为推动电子商务行业创新与变革的关键力量。在电子商务领域，个性化推荐系统作为大数据应用的重要场景之一，正深刻改变着用户的购物体验和商家的销售策略。然而，大数据在电子商务个性化推荐中的应用并非一帆风顺，其面临着数据质量参差不齐、用户隐私泄露风险、推荐算法局限性以及实时性与动态性挑战等诸多问题。这些问题不仅影响了推荐系统的准确性和用户满意度，也制约了电子商务行业的进一步发展。本文概述了大数据理论、电子商务理论以及个性化推荐系统的基本原理，为后续分析奠定理论基础。随后，深入分析了大数据在电子商务个性化推荐中的重要作用，包括提升用户体验、促进商品销售以及深化市场洞察等方面。紧接着，本文详细阐述了大数据在电子商务个性化推荐中面临的四大问题：数据质量问题、隐私保护问题、推荐算法局限性以及实时性与动态性挑战，并针对每个问题提出了具体的解决对策。在数据质量优化方面，提出了数据预处理与清洗、数据增强与稀疏性缓解等策略；在隐私保护方面，探讨了匿名化与差分隐私技术、用户授权与透明度提升等方法；在推荐算法改进方面，介绍了混合推荐算法、冷启动解决方案等前沿技术；在实时性与动态性提升方面，则强调了分布式与并行处理技术、用户兴趣建模与更新等关键措施。最后，本文总结了研究成果，并展望了大数据在电子商务个性化推荐中的未来发展趋势。

Abstract
With the rapid development of Internet technology, big data has become a key force to promote the innovation and change in the e-commerce industry. In the field of e-commerce, personalized recommendation system, as one of the important scenarios of big data application, is profoundly changing the users 'shopping experience and merchants' sales strategy. However, the application of big data in e-commerce personalized recommendation is not smooth sailing, and it is faced with many problems such as uneven data quality, risk of user privacy leakage, limitations of recommendation algorithms, and real-time and dynamic challenges. These problems not only affect the accuracy of the recommendation system and user satisfaction, but also restrict the further development of the e-commerce industry. This paper summarizes the basic principles of big data theory, e-commerce theory and the basic principles of personalized recommendation system, laying the theoretical foundation for subsequent analysis. Subsequently, an in-depth analysis of the important role of big data in e-commerce personalized recommendation, including improving user experience, promoting product sales and deepening market insight. Then, this paper expounds the four major problems faced by big data in the personalized recommendation of e-commerce: data quality, privacy protection, limitations of recommendation algorithm and real-time and dynamic challenges, and puts forward specific solutions for each problem. In terms of data quality optimization, propose data preprocessing and cleaning, data enhancement and sparsity mitigation; privacy protection, discuss anonymity and differential privacy technology, user authorization and transparency improvement; hybrid recommendation algorithm and cold start solution; real-time and dynamic improvement, emphasize the key measures of distributed and parallel processing technology and user interest modeling and updating. Finally, this paper summarizes the research results and prospects the future development trend of big data in personalized e-commerce.
