Note that these alignments are noisy (e.g., [mean] aligns to a period).
for each record (skyCover and temperature in this case), we extract two templates: (1) a COARSE template, which takes the text spanned by the record and abstracts away all fields in the scenario ( For each record r i , we define T i so that BASE(T i ) and COARSE(T i ) are the corresponding two extracted templates.
