本文提出了一种基于专利组合的企业间技术距离度量方法。我们通过应用语言建模技术框架对公司的专利组合进行信息检索来描述公司的技术地位或特征。所提出的新方法是一种不对称度量，能够更好地捕捉公司的技术特征，因此是一种更准确的距离度量。
This article introduces a novel technological distance measure between companies based on their patent portfolios. We describe the technological position or characteristics of companies by applying the framework of language modelling technique in information retrieval on their patent portfolios. The proposed novel approach is an asymmetric measure and better captures the technological characteristic of a company and hence is a more accurate distance measure.
