摘要
硬科技创新是原创性高精尖科技和实体经济的结合,对我国未来创新驱动发展起着巨大推动作用,有助于形成核心竞争力。识别硬科技创新主题在情报学领域仍是一个新课题,对其有效识别将有助于引导社会投资,及早挖掘新的经济增长点。本文以石墨烯领域为研究样本,结合学术型发明人的论文和专利,基于LDA2Vec主题模型和K-means聚类算法进行硬科技创新候选技术主题挖掘;通过发文强度、时序性分析筛选主题,根据学术型发明人主题关注度、高校及科研院所主题关注度、基金投资强度构建三维评价模型,筛选出最有可能成为硬科技创新的技术主题。结果表明,石墨烯电池等7个技术主题最有可能成为石墨烯领域内硬科技创新主题,为后续相关研究提供思路。
The key & core technology innovation is a combination of real economy and advanced technology.It also plays an important role in promoting future innovation-driven development and forming core competitiveness.At present,identifying the key & core technology innovation is still a new topic in the field of information science.Effect identification of key & core technology innovation will help to guide the social investment,and find out new economic growth point.Graphene field is used as the study sample,the technical theme is identified based on the LDA2 Vec theme model which used papers and patents of the academic inventors.The themes are selected by the intensity and timing analysis,and a 3 D model is made according to the attention of academic leaders,the degree of commercialization of scientific research institutions and the intensity of the fund amount.It is concluded that 7 technical topics including graphene batteries are most likely to become the key & core technology innovation topics,providing ideas for subsequent related researches.
