Abstract: Advancements in the coverage and efficacy of pre-trained language models have paved the way for future research in natural language processing by making it much easier generalize from small hand-annotated datasets. In cases that require inputs from situational context, however, pre-trained models may not reliably learn to disambiguate grounded language. Using the case of PP attachment in image captions, I assess the learning potential of pre-trained statistical language models toward resolving ambiguity in image captions. My results show that pre-trained models may lack the context required to resolve the ambiguity in many cases, but traditional NLP approaches can be combined with statistical models for grounded learning.
