This paper investigates syntactic productivity in diachrony with a data-driven approach. Previous research indicates that syntactic productivity (the property of grammatical constructions to attract new lexical fillers) is largely driven by semantics, which calls for an operationalization of lexical meaning in the context of empirical studies. It is suggested that distributional semantics can fulfill this role by providing a measure of semantic similarity between words that is derived from lexical co-occurrences in large text corpora. On the basis of a case study of the construction “V
a b s t r a c tA growing emphasis on statistics in language learning raises the question of whether and when speakers use language in ways that go beyond the statistical regularities in the input. In this study, two groups were exposed to six novel verbs and two novel word order constructions that differed in function: one construction but not the other was exclusively used with pronoun undergoers. The distributional structure of the input was manipulated between groups according to whether each verb was used exclusively in one or the other construction (the lexicalist condition), or whether a minority of verbs was witnessed in both constructions (the alternating condition). Production and judgments results demonstrate that participants tended to generalize the constructions for use in appropriate discourse contexts, ignoring evidence of verb-specific behavior, especially in the alternating condition. Our results suggest that construction learning involves an interaction of witnessed usage together with the functions of the constructions involved.
How do people learn to use language in creative but constrained ways? Experiment 1 investigates linguistic creativity by exposing adult participants to two novel word order constructions that differ in terms of their semantics: One construction exclusively describes actions that have a strong effect; the other construction describes actions with a weaker but otherwise similar effect. One group of participants witnessed novel verbs only appearing in one construction or the other, while another group witnessed a minority of verbs alternating between constructions. Subsequent production and judgment results demonstrate that participants in both conditions extended and accepted verbs in whichever construction best described the intended message. Unlike related previous work, this finding is not naturally attributable to prior knowledge of the likely division of labor between verbs and constructions or to a difference in cue validity. In order to investigate how speakers learn to constrain generalizations, Experiment 2 includes one verb (out of 6) that was witnessed in a single construction to describe both strong and weak effects, essentially statistically preempting the use of the other construction. In this case, participants were much more lexically conservative with this verb and other verbs, while they nonetheless displayed an appreciation of the distinct semantics of the constructions with new novel verbs. Results indicate that the need to better express an intended message encourages generalization, while statistical preemption constrains generalization by providing evidence that verbs are restricted in their distribution.
This paper presents a corpus-based study of recent change in the Englishway-construction, drawing on data from the 1830s to the 2000s. Semantic change in the distribution of the construction is characterized by means of a distributional semantic model, which captures semantic similarity between verbs through their co-occurrence frequency with other words in the corpus. By plotting and comparing the semantic domain of the three senses of the construction at different points in time, it is found that they all have gained in semantic diversity. These findings are interpreted in terms of increases in schematicity, either of the verb slot or the motion component contributed by the construction.
