摘要: 为有效提升图书信息资源服务智能检索效率和性能, 提出一种基于机器学习算法的图书信息资源服务智能检索方法。采用机器学习算法对图书的关键词词频分类, 给出每个类对应的指数, 计算分类中每个文档对应的特征词权重, 经反复迭代获取特征词的评分; 建立语境特征矩阵, 计算每个类的相应得分, 并对选择得分最高的特征进行分类处理。结合图书信息资源分类结果, 引入网格计算技术构建图书信息资源服务智能检索模型, 利用其实现图书信息资源服务智能检索。实验结果表明, 使用所提方法进行图书信息资源服务智能检索时, 得到的查准率在 96. 0% 以上、查全率保持在 90% 以上、在不同数据集下的检索用时均在450 ms左右, 表明所提方法具有良好的图书信息资源服务智能检索性能。

Abstract: In order to effectively improve the efficiency and performance of intelligent retrieval of book information resource services, a machine learning algorithm based intelligent retrieval method is proposed. Machine learning algorithms are used to classify the keyword frequency of books, providing the corresponding index for each class, calculating the weight of feature words corresponding to each document in the classification,and obtaining the score of feature words through repeated iterations. A contextual feature matrix is established,the corresponding score for each class is calculated, and the feature with the highest score is selected for classification processing. Based on the classification results of book information resources, grid computing technology is introduced to construct an intelligent retrieval model for book information resource services, and the model is used to achieve intelligent retrieval of book information resource services. The experimental results show that when using the proposed method for intelligent retrieval of book information resource services, the precision obtained is above 96. 0% , the recall rate remains above 90% , and the retrieval time under different datasets is around 450 ms, indicating that the proposed method has good performance in intelligent retrieval of book information resource services.

Key words: machine learning algorithms, book information, grid computing technology, resource services, intelligent retrieval
