摘要 

電子病歷（Electronic medical records，EMR）產(chǎn)生于臨床治療過程，其中命名實體和實體關(guān)系反映了患者健康狀況，包含了大量與患者健康狀況密切相關(guān)的醫(yī)療知識，因而對它們的識別和抽取是信息抽取研究在醫(yī)療領(lǐng)域的重要擴(kuò)展. 本文首先討論了電子病歷文本的語言特點和結(jié)構(gòu)特點，然后在梳理了命名實體識別和實體關(guān)系抽取研究一般思路的基礎(chǔ)上，分析了電子病歷命名實體識別、實體修飾識別和實體關(guān)系抽取研究的具體任務(wù)和對應(yīng)任務(wù)的主要研究方法. 本文還介紹了相關(guān)的共享評測任務(wù)和標(biāo)注語料庫以及醫(yī)療領(lǐng)域幾個重要的詞典和知識庫等資源. 最后對這一研究領(lǐng)域仍需解決的問題和未來的發(fā)展方向作了展望.
