The *Discovery* datasets consists of adjacent sentence pairs (s1,s2) with a discourse marker (y) that occurred at the beginning of s2. They were extracted from the depcc web corpus. Markers prediction can be used in order to train a sentence encoders. Discourse markers can be considered as noisy labels for various semantic tasks, such as entailment (y=therefore), subjectivity analysis (y=personally) or sentiment analysis (y=sadly), similarity (y=similarly), typicality, (y=curiously) ... The specificity of this dataset is the diversity of the markers, since previously used data used only ~10 imbalanced classes. The author of the dataset provide: - a list of the 174 discourse markers - a Base version of the dataset with 1.74 million pairs (10k examples per marker) - a Big version with 3.4 million pairs - a Hard version with 1.74 million pairs where the connective couldn't be predicted with a fastText linear model Source: GitHub
