This dataset contains tabular files recording occurrences of the verb REGRET complemented by a finite or non-finite complement clause (CC) in the GloWbE corpus. Tokens were retrieved using the online interface (https://www.english-corpora.org/glowbe/) and manually annotated for several syntactic and semantic variables (variety, L1 vs L2, CC_pattern, finiteness, negative marker, negation_yes/no, and temporal relation). See ReadMe file for more details. Related publication: Romasanta, Raquel P. 2021. Negation as a predictor of clausal complement choice in World Englishes.
