摘要
利用文本挖掘技术,并结合科学计量、自然语言处理等方法,提出一种基于三重共现算法的技术路线图中未来技术词表构建方法,以揭示特定技术领域的未来技术发展方向和未来发展阶段水平特征,初步实现技术路线图中的未来技术分析目标。实验表明该方法能够在一定程度上支持技术路线图的未来技术分析研究。
The paper proposes a triple co - occurrence algorithm to construct the future - oriented technology thesaurus of technology roadmap based on text mining combining the method of seientometries and natural language processing, which reveals the future - oriented technology development direction and level characteristics of special technical field and achieves preliminarily the target of future - oriented technology analysis of technology roadmap. The experiment shows that this method can support the future - oriented technology analysis of technology roadmapping to some extent.
