摘要：

目的乳腺超声图像本体有助于乳腺超声图像语义标注、智能检索等。本文以乳腺超声图像为例，论述了乳腺超声图像的本体模型构建方法。方法首先通过主题词与语料高频词结合的方法确定乳腺超声图像本体的概念，然后借鉴UMLS提炼乳腺超声图像本体的语义关系。结果本研究构建的乳腺超声图像本体具有1274个概念，56种语义关系，通过PROGTéGé构建了乳腺超声图像本体。结论以主题词与语料高频词结合的方法确定的本体概念具有较好的乳腺超声图像语义刻画效果，本文所述的乳腺超声图像本体构建方法也适用于其他领域本体的构建。

Objective The ontology of breast ultrasound images can help the study of semantic annotation and intelligent retrieval system. In this paper, we try to build the ontology model of breast ultrasound images. Methods First, we determine ontological concepts of breast ultrasound images by keyword combined with corpus high-frequency words. Second, we extend ontological semantic relations of breast ultrasound images based on UMLS. Results The ontology of breast ultrasound images consists of 1274 concepts and 56 kinds of semantic relationships. The ontology is constructed through PROGTéGé. Conclusions The screening method of ontological concepts that is implemented with keywords and corpus high-frequency words here has a better semantic characterization result in describing the breast ultrasound images. This method is applicable to other areas in ontological building as well.
