  abstract  = {In this paper, we propose using metaheuristics---in particular, simulated
	annealing and the new D-Bees algorithm---to solve word sense disambiguation as
	an optimization problem within a knowledge-based lexical substitution system. 
	We are the first to perform such an extrinsic evaluation of metaheuristics, for
	which we use two standard lexical substitution datasets, one English and one
	German.  We find that D-Bees has robust performance for both languages, and
	performs better than simulated annealing, though both achieve good results. 
	Moreover, the D-Bees--based lexical substitution system outperforms
	state-of-the-art systems on several evaluation metrics.  We also show that
	D-Bees achieves competitive performance in lexical simplification, a variant of
	lexical substitution.},
