摘要： 针对如何在相似媒体之间进行有效关联，描述跨媒体的相似性等问题，提出一种新的跨媒体检索方法。提取多媒体对象的低层特征，利用Ontology对其进行组织，在语义层次实现多媒体关联。实验结果证明，基于Ontology的方式可以有效完成跨媒体检索。

Abstract: With the rapid development of information retrieval, cross-media retrieval is becoming a hotpoint, but a few problems haven’t been resolved such as upbuilding effective correlations and calculating similarity between different kinds of media objects. This paper brings up a new method, and uses Ontology to organize different media objects. Experimental results show that this method based on Ontology is effective for cross-media retrieval.

Key words: cross-media retrieval, Ontology, retrieval extension, similarity calculation
