摘要:

目的 乳腺超聲圖像本體有助于乳腺超聲圖像語(yǔ)義標(biāo)注、智能檢索等。本文以乳腺超聲圖像為例,論述了乳腺超聲圖像的本體模型構(gòu)建方法。方法 首先通過主題詞與語(yǔ)料高頻詞結(jié)合的方法確定乳腺超聲圖像本體的概念,然后借鑒UMLS提煉乳腺超聲圖像本體的語(yǔ)義關(guān)系。結(jié)果 本研究構(gòu)建的乳腺超聲圖像本體具有1274個(gè)概念,56種語(yǔ)義關(guān)系,通過PROGTéGé構(gòu)建了乳腺超聲圖像本體。結(jié)論 以主題詞與語(yǔ)料高頻詞結(jié)合的方法確定的本體概念具有較好的乳腺超聲圖像語(yǔ)義刻畫效果,本文所述的乳腺超聲圖像本體構(gòu)建方法也適用于其他領(lǐng)域本體的構(gòu)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.
