Quantifying cross-disciplinary knowledge flow from the perspective of content: Introducing an approach based on knowledge memes

作者：

Highlights：

• Knowledge memes that are a special type of knowledge units are identified.

• Diffusion cascade is applied to model the diffusion process of knowledge memes.

• Knowledge relationships among disciplines measured by knowledge memes are different from those measured by citations.

• Preferential attachment takes effect in cross-disciplinary knowledge meme diffusion.

• Patterns of cross-disciplinary knowledge memes are disclosed.
