標(biāo)準(zhǔn)解讀

《GB/T 45257-2025 新聞出版 知識服務(wù) 知識元提取與標(biāo)引》這一標(biāo)準(zhǔn)，旨在為新聞出版行業(yè)提供一套規(guī)范化的知識元提取及標(biāo)引方法。它適用于新聞媒體、出版社等機(jī)構(gòu)在處理信息時對內(nèi)容進(jìn)行結(jié)構(gòu)化處理，以便于后續(xù)的知識組織、檢索和利用。

該標(biāo)準(zhǔn)首先定義了“知識元”概念，即構(gòu)成某一領(lǐng)域或主題下最小單位的信息片段，這些片段能夠獨立表達(dá)完整意義，并且具有可標(biāo)識性。接著，標(biāo)準(zhǔn)詳細(xì)描述了如何從文本中識別出這樣的知識單元，包括但不限于人名、地名、時間、事件等實體信息的自動抽取技術(shù)指南。同時，對于非結(jié)構(gòu)化數(shù)據(jù)如圖片、音頻視頻等內(nèi)容中的關(guān)鍵信息提取也給予了指導(dǎo)建議。

在知識元標(biāo)引方面，《GB/T 45257-2025》提出了基于語義網(wǎng)技術(shù)的解決方案，通過建立統(tǒng)一資源標(biāo)識符（URI）來唯一確定每一個被提取出來的知識元素，并使用RDF（資源描述框架）格式對其進(jìn)行編碼存儲。此外，還強(qiáng)調(diào)了利用本體論（Ontology）構(gòu)建領(lǐng)域知識模型的重要性，以增強(qiáng)不同系統(tǒng)間的數(shù)據(jù)互操作能力。
