Batch recommendation of experts to questions in community-based question-answering with a sailfish optimizer

作者:

Highlights:

• Batch recommendation of answerers to questions is proposed.

• Activeness, recency, and professionalism are defined to measure expertise.

• Coverage, answerability and expert resource consumption are defined as objectives.

• A discrete sailfish swordfish optimizer with a genetic algorithm is constructed for clustering.

• A binary multiobjective sailfish swordfish optimizer with a genetic algorithm is constructed.
