Manifesto Project example manifestos and gold-standard segmentation

data_corpus_MPexamples.Rd

Two datasets derived from Appendix 2 of Klingemann et al. (2006), which provides worked examples of the Manifesto Project quasi-sentence coding scheme.

data_corpus_MPexamples is a two-document corpus containing the full source texts of the Liberal-SDP Alliance 1983 UK election manifesto and the New Zealand National Party 1972 election manifesto, reconstructed by joining the quasi-sentences from the gold-standard annotation.

data_corpus_MPexamplesseg is the corresponding gold-standard segmented corpus, produced by converting the Manifesto Project's human-coded quasi-sentences via as_qlm_coded() with qlm_segment = TRUE. It is marked as a gold standard (is_gold = TRUE) and can be passed directly to qlm_compare() alongside output from qlm_segment() to compute Krippendorff's alpha for unitizing.
