Conférence: Semantic vs. World Knowledge Conflicts: An Experiment upon Differentiation and Gradation

This talk investigates the interplay between world knowledge and semantic knowledge. Specifically, it examines whether violations of world knowledge (conceptual conflicts) differ cognitively from violations of semantic knowledge (semantic conflicts), and whether this distinction, should it exist, is best conceived as binary or as a gradual continuum.
To address this question, we designed an experiment with item sets comprising four conditions in which only the direct object varies. The conditions are defined by the selection restrictions of the predicate and the ontology proposed by Metzger et al. (2018): (a) compositional baseline, in which restrictions are fully satisfied; (b) conceptual conflict, in which restrictions are satisfied but the sentence is implausible according to world knowledge; (c) near semantic conflict, in which the argument deviates within the category or stems from a neighboring one; and (d) far semantic conflict, in which the argument comes from a category at least two levels higher and one aside from the target.
An online acceptability judgment experiment was conducted with 36 item sets and 120 native German speakers. We predict that all three conflict conditions (KonK, SemKN, SemKF) will receive significantly lower acceptability ratings than the compositional baseline (Komp). Furthermore, we expect acceptability to differ significantly between conceptual and semantic conflicts, but not between near and far semantic conflicts.
The study employs carefully constructed item sets comprising four experimental conditions, exemplified as follows:
(1) a. Der Praktikant hat eine Einzimmerwohnung bewohnt. (compositional; Komp)
DF.M.NOM.SG intern.M.NOM.SG have-AUX.3SG INDF.F.ACC.SG one-room-apartment.F.ACC.SG inhabit-PTCP
„The intern has lived in a one-room apartment. “
b. ?Der Praktikant hat eine Badewanne bewohnt. (conceptual conflict; KonK)

„The intern has lived in a bathtub. “
c. #Der Praktikant hat ein Haargummi bewohnt. (near semantic conflict; SemKN)
