Expert knowledge recommendation systems based on conceptual similarity and space mapping

作者：

Highlights：

• EKRS is constructed by concept similarity and space mapping between CRD and IR.

• the new concept set is formed after sorting by shortest path between concepts.

• the higher similarity and the better conceptual aggregation in EKRS.

• the structure is simple and the computational complexity is much lower in EKRS.

• the EKRS has good stability in dealing with different concept sets.
