知识演化视角下的人工智能领域论文与专利的技术方法对比分析——以自然语言处理领域为例

Comparative analysis of technical methods of papers and patents in artificial intelligence field from the perspective of knowledge evolution

摘要:

[背景]人工智能领域的学术研究与工业实践之间存在紧密联系,研究成果在二者之间转移流动。[目的/意义]揭示自然语言处理领域论文与专利中的技术方法的分布及其演化趋势,分析二者的关联与差异。[方法/过程]构建方法本体,将论文和专利映射到本体中,采用配对样本T检验方法验证两者知识演化的滞后性。[结果/结论]:论文与专利存在共同关注的技术方法,配对样本T检验的结果显示专利技术方法相对论文滞后约1-2年。

Abstract:

[1]:[Background]There is a close relationship between academic research and industrial practice in the field of artificial intelligence, and research results flow between them. [Purpose/Significance]To reveal the distribution and evolution trend of technical methods in papers and patents in the field of natural language processing, and analyze the correlation and differences between them. [Methods/Process]Method ontology was constructed, papers and patents were mapped into ontology, and the lag of their knowledge evolution was verified by paired sample T-test. [Results/Conclusion] The paper and the patent have common technical methods, and the results of paired sample T test show that the patented technical methods lag behind the paper by about 1-2 years.
