Addressing topic modeling with a multi-objective optimization approach based on swarm intelligence
作者:
Highlights:
• Topic Modeling (TM) has been addressed from a multi-objective point of view.
• A new approach based on MOABC has been designed, implemented, and applied to TM.
• Three objective functions have been optimized: coherence, coverage, and perplexity.
• Documents from the Reuters-21578 and TagMyNews datasets have been used for evaluation.
• Results show that MOABC provides relevant improvements with respect to LDA and MOEA/D.
