基于GTM的3D生物打印专利技术空白点识别

Identification of Patent Vacuums in 3D Bioprinting Based on GTM

专利技术空白点是一个技术领域中尚未开发,但具有很强的技术创新潜力的部分。利用生成式拓扑映射(GTM)方法,绘制3D生物打印技术的专利地图,寻找3D生物打印领域的技术空白点。通过生成式拓扑映射将空白点逆向映射到关键词向量空间中,找到各个空白点所代表的技术含义,以供企业和研究人员确定研发战略,判断未来的创新重点。

Using the generative topographic mapping（GTM）,this paper develops the patent map of 3D bioprinting technology to help i-dentify the patent vacuums in the field of 3D bioprinting technology. Patent vacuums are transformed to the keyword vector through inverse mapping in order to provide the original meaning of the patent vacuum,which can help enterprises and researchers to identify the research＆amp;development strategy and determine the future focuses of innovation.
