This effect occurs throughout a distributed network, which suggests that propositional sentence-level meaning is represented within and across multiple cortical regions rather than at any single site.
Using voxelwise encoding modeling, we demonstrate that InferSent predicts elements of fMRI activation that cannot be predicted by bag-of-words models and sentence models using grammatical rules to assemble word vectors. Recurrent connections and nonlinear filters enable InferSent to transform sequences of word vectors into unified “propositional” sentence representations suitable for evaluating intersentence entailment relations. To address this issue, we interrogated fMRI activation elicited as 240 sentences were read by 14 participants (9 female, 5 male), using sentences encoded by a recurrent deep artificial neural-network trained on a sentence inference task (InferSent). This is because models have typically represented sentences as “bags-of-words” that neglect sentence-level structure. However, it remains unclear whether activation patterns within regions reflect unified representations of sentence-level meaning, as opposed to superpositions of context-independent component words. These studies have helped map out semantic representation across a distributed brain network spanning temporal, parietal, and frontal cortex. Recent advances have begun to explain brain activation elicited by sentences using vector models of word meaning derived from patterns of word co-occurrence in text corpora. If you look for a plural word, use a singular word.Understanding how and where in the brain sentence-level meaning is constructed from words presents a major scientific challenge.
The ASL signs for French and France are the same. Likewise, if you look for an adjective word, try the noun or vice versa. If you look for "said", look up the word "say". For search in the dictionary, use the present-time verbs and base words. For plurals, verb inflections, word order, etc., learn grammar in the "ASL Learn" section.
