Enhancing long tail item recommendation in collaborative filtering: An econophysics-inspired approach

作者:

Highlights:

• A novel viewpoint of econophysics principles is formulated to address long tail effect.

• Rating injection strategy inspired from econophysics principles is proposed.

• Performance of the proposed method is evaluated on long tail and non-long tail items.

• Proposed approach immensely improved the number of long tail items in recommendations.

• The proposed principles can be applied as an add-on to state-of-the-art recommendation technique.
