中文摘要: 伴随着计算机信息技术的快速发展,电子商务以其方便、快捷、经济等优点迅速得到了人们的青睐,积累了大量的诸如商品描述、用户评论等电子商务大数据。电子商务大数据的异构性、高维性、相关度高和快速更新等特性导致传统的数据存储和查询处理技术无法满足电子商务大数据查询处理应用的实际需求,使得如何提供更加符合用户需求的商品搜索成为亟待解决的重要问题。本项目研究结合用户主观查询输入和用户客观偏好特征的以用户为中心的电子商务大数据偏好查询处理与优化问题,重点研究结合用户主观输入和用户客观偏好的查询语义、统筹原始数据异构性和特征向量高维性的数据存储、以用户为中心的分布式偏好查询处理与优化技术,并设计实现一个以用户为中心的电子商务大数据偏好查询处理与优化原型系统来验证研究成果的正确性和有效性。研究成果将为电子商务大数据偏好查询处理应用提供有力的理论支持和解决方案,具有重要的理论研究意义和实际应用价值。

英文摘要: With the rapid development of computer information techniques, the E-Commerce has been welcomed by people for the characteristics of convenient, fast, economy and so on. The amount of E-Commerce data increases sharply, such as the products descriptions data and the user reviews data. The characteristics of E-Commerce big data are isomerism, high-dimensionality, high relevancy and quick updating, which lead the traditional techniques of data storage and query processing cannot satisfy the practical application requirements of E-Commerce big data. How to provide the search with the user requirements has become the urgent problem. This project researches the preference query processing and optimization problem of E-Commerce big data combining the query input and the preference features of users. The important research problems are the query semantics of combining the query input and the preference features of users, data storage with isomerism and high-dimensionality, the distributed preference query processing and optimization for user-centered design. A original system of preference query processing for user-centered design will be designed in this project to verify the correctness and efficiency of the research results. The results will offer efficient theoretical supporting and solutions for preference query processing applications of E-commerce big data, which have important theoretical research significance and practical application value.
