SlowGuess/NAACL_2022_OCR huggingface dataset:
Supervised model. For the implementation of the supervised model described by (Charbonnier and Wartena, 2019) we used 3 feature types. For POS tag, we used the WordNet module from the NLTK package to find, for each word, the number of synsets in each of the 4 possible POS tags (NOUN, VERB, ADJ, ADV), and the induced feature vector was the normalized count vector. In case no synsets were found the induced feature vector was all zeros. For suffixes, we collected the 200 most frequent suffixes of length 1 to 4 characters in the training set, and the induced feature vector was a 200-d binary vector indicating, for each suffix, if it occurs in the current word. For word embeddings, we used the fastText wiki-news-300d-1M model. The final feature vector is the concatenation of all the selected feature vectors: POS+suffix for the first model (resulting a 204-d feature vector for each word), and POS+suffix+embedding for the second model (resulting a 504-d feature vector for each word).
Text-only baseline. The 20 concrete representative words were sand, seagull, snake, snowsuit, spaghetti, stairs, strawberry, tiger, tomato, tooth-brush, tractor, tree, turtle, umbrella, vase, water, comb, tire, firetruck, tv.
The 20 abstract representative words were would, if, though, because, somewhat, enough, as, could, how, yet, normal, ago, so, very, the, really, then, abstract,  $a$ , an.
A.1.4 Object Localization
To extract Class Activation Mappings, we used the CAM module from the torchcam package.
