| 摘 要： | 目的/意义]以现有图书馆借阅记录为基础，结合图书阅读相关性进行深入挖掘，探讨识别借阅场景下图书专业性质量和实现相应个性化图书推荐服务的有效方法。方法/过程]利用图书的阅读相关性提出图书相关性链接关系，结合图书质量的迭代识别算法来识别专业图书资源。同时利用图书类别相关性链接关系，提出读者用户个性化模式的表达方法，并从长期兴趣推荐和短期兴趣的即时推荐两个方面给出个性化图书推荐策略设计原理和实现方法。结果/结论]在图书质量识别方面，该方法更易于识别出专业性较强的优质图书资源，适用面比较灵活，也可以在限定图书范围内进行专业图书识别。在个性化图书推荐方面，发现不论长期兴趣推荐方法还是短期兴趣推荐方法，第二类用户的平均推荐命中度要高于第一类用户，在第一类用户中，最高相似度区间（75%以上）和较低相似度区间（15%-50%）的短期兴趣推荐方法的平均推荐命中度要高于长期兴趣推荐方法。本研究通过读者借阅序列分析方法识别专业图书并实现相应的个性化推荐图书方法，有利于改善现有图书馆借阅服务水平和提高读者的满意度。

| Abstract: | Purpose/significance] With the analysis of the existing library records and mining of the reading relevance of books, this paper discusses the effective methods to identify high-quality professional books and implement a personalized recommendation service. Method/process] This paper introduces the iterative algorithm of recognizing high-quality professional books from links of books relevance based on reading relevance. Then the construction of reader personalized profile is discussed based on the definition of links of book categories. The design and implementation of long-term and short-term personalized recommendation methods are also proposed. Result/conclusion] In the aspect of book quality identification, it is easier to identify the professional books resources with higher quality. This application is more flexible and also can identify the high-quality professional books within the collection of specific books. It is found that whether long-term or short-term interest interest recommendation method, the average hit degree of users with higher lending is higher than users with lower lending. In the group of users with higher lending, the average hit degree of short-term interest recommendation method in the highest similarity range (more than 75%) and lower similarity range(15% to 50%) is higher than the long-term interest recommendation method. |
