摘　　要：本体整合和评估时,随着本体库中元素数目的增大,会造成时间和空间的浪费。为了解决该问题,对本体的相似度算法进行了研究,提出了一种基于本体片段映射的算法,通过截取本体中相关片段进行映射。结合电子消费品领域的领域本体实例对算法进行了分析,该算法不仅可以提高大规模本体映射时的效率,同时为进行本体整合和评估提供了一种新的方法。In operations of ontology integration and evaluation,the increasement of the quantity of elements of ontology leads to a waste of time and space.To solve this problem,research on ontology similarity is done.An algorithm based on ontology fragment mapping is proposed,which is achieved by ontology relevant fragment mapping.An ontology instance in consumer electronics field is established and the proposed algorithm is well studied.The proposed algorithm improves the efficiency of large-scale ontology mapping and provides a new approach to ontology integration and evaluation.
