Recent work on predicting category structure with distributional models,
using either static word embeddings (Heyman and Heyman, 2019) or contextualized
language models (CLMs) (Misra et al., 2021), report low correlations with human
ratings, thus calling into question their plausibility as models of human
semantic memory. In this work, we revisit this question testing a wider array
of methods for probing CLMs for predicting typicality scores. Our experiments,
using BERT (Devlin et al., 2018), show the importance of using the right type
of CLM probes, as our best BERT-based typicality prediction methods
substantially improve over previous works. Second, our results highlight the
importance of polysemy in this task: our best results are obtained when using a
disambiguation mechanism. Finally, additional experiments reveal that
Information Contentbased WordNet (Miller, 1995), also endowed with
disambiguation, match the performance of the best BERT-based method, and in
fact capture complementary information, which can be combined with BERT to
achieve enhanced typicality predictions
