| 摘 要： | 【目的/意义】从计量语言学视角描述和揭示融合主题指纹的科学知识系统的语言分布规律,并选取语料进行验证,深化情报检索语言的理论和应用研究,也为知识抽取研究提供理论基础和实验素材。【方法/过程】以生物医学领域的"疾病"、"精神病学和心理学"和"现象和过程"三个类别分支为入口,选取乳腺癌、焦虑抑郁、免疫作为案例,并量化分析其代表性。运用齐普夫定律(Zipf’s Law)和希普斯定律(Heaps’Law)解释验证由主题指纹映射的科学知识系统的计量语言学特征。【结果/结论】融合主题指纹的科学知识系统具有计量语言学特征,符合科学信息的离散分布规律和演化定律,具有较好的科学性和稳定性。

| Abstract: | 【Purpose/significance】From the perspective of quantitative linguistic, this paper interprets and reveals the language distribution law of the scientific knowledge system based on integrating subject fingerprints, and therefore selects corpus for verification. This paper totally deepens the theoretical and applied research of the information retrieval language,and provides the theoretical basis and experimental material for knowledge extraction research.【Method/process】This paper chooses three cases which are breast neoplasms, depressive disorders and anxiety disorders and immunity from the three categories of "diseases", "psychiatry and psychology" and "phenomena and processes" in the field of biomedicine,aiming to do a quantitative analysis of its representativeness. While we use Zipf’s Law and Heaps’ Law to interpret and verify the quantitative linguistic features of the scientific knowledge system mapped by subject fingerprints.【Result/conclusion】The scientific knowledge system based on integrating subject fingerprints has the characteristics of quantitative linguistics,which conforms to the law of discrete distribution and evolution of scientific information,and it is scientific and stable. |
