Improving the reliability of short-term citation impact indicators by taking into account the correlation between short- and long-term citation impact

作者：

Highlights：

• The normalized indicator may not be reliable when a short citation window is used.

• To solve this problem, we introduce a weighting factor to the normalized indicator.

• The weight reflects the degree of reliability of the normalized indicator.

• The weighted indicator overcomes the disadvantage of the new crown indicator.

• After introducing the weight, some universities’ rankings changed dramatically.
