5 Options for training seeds
- What strategies can supply seed collocations?Words from dictionary definitions of each sense (weighted by how reliable their collocations are); a single defining collocate per sense (e.g. bird and machine for crane, from WordNet); or a human quickly labelling salient corpus collocates (flock, bulldozer), typically in a couple of minutes.

- How did the seed strategies compare?Two words as seeds already did surprisingly well; dictionary definitions did better by covering more of each sense’s concept space (though example sentences add noise); quick hand labelling of salient collocates did best, at minimal cost.
