There are 1,250 sentences in total, each individually annotated. The dataset uses the BIO annotation format, where each element is labeled as "B-X", "I-X", or "O". Specifically, "B-X" indicates that the segment containing this element belongs to type X and this element is at the start of the segment; "I-X" indicates that the segment belongs to type X and this element is in the middle of the segment; "O" indicates that the element does not belong to any type.
