“…In general, the existing mechanistic models that learn operational computational construction grammars (i.e. class one and two) have explored interesting ideas on a rather small scale, either because they were limited to specific linguistic phenomena [33,53,54,[57][58][59][60]65,66], or because of the limited morpho-syntactic and semantic complexity of the input utterances [50,52,61,62,64,69,[71][72][73]. In all of the aforementioned work except [67,68], either a segmentation of the input utterances, a lexicon or a set of predefined grammatical categories was provided.…”
