Outline

• The data for extracting metadata from PDF domestic papers.

• The file named as “valid.txt” was developed through the manual inspection process by several annotators. It contains a total of 155,629 labeled layout boxes for 9,895 papers in 503 journals.
• The file named as “test.txt” was built through the manual inspection process. It contains a total of 159,925 labeled layout boxes for 10,119 papers in 503 journals. It was used as test set.

Data format(TXT)
