一种有效的图书本体学习算法

摘要

To solve the bottleneck problem of ontology learning and integration in ontology construction,an ontology learning algorithm was suggested.The algorithm applied the tree structure,added and pruned the concepts and their relations in a hierarchical manner and designed two procedures for the corresponding ontology learning.According to retrieval features of books,the book ontology was divided into external and content ontology to respectively learn two kinds of ontology construction of books.A book retrieval system was developed by using the ontology learning algorithm.The results show that the algorithm can effectively realize the accurate retrieval of books.%为了解决本体的学习和集成在本体构建中的瓶颈问题,提出一种本体学习算法;该算法利用树形结构,以分层的方式进行概念及其关系的添加与剪枝,设计相应的本体学习的2个主要过程;根据图书的检索特征,将图书本体分为图书外部本体和内容本体,可以分别学习图书的2类本体结构;给出利用学习到的本体实现图书检索系统的应用实例.结果表明:该本体学习算法可以有效地实现图书的准确检索.
