Since traditional overlapping community detection methods in complex networks based on label propagation that could not detect overlapping nodes accurately

this paper presented link attribution density and link attribution orientation functions through analyzing the relationship between each link and its neighbor links to assess the attribution community of each link.On this basis

overlapping community detection method based on link label propagation (OLLP) was designed.Firstly

OLLP used the label of every link to the node label which possesses the higher degree when connected by the link

and then updated the label repeatedly through analyzing attribution density and attribution orientation of the link.Finally

identical label links were attributed to the same community.By testing on both synthetic and real-world networks

and comparing with multiple representative algorithms

the experimental results verify the validity and feasibility of OLLP.
