+
+## Outline
+- The corpus for extracting metadata from multilingual journal references.
+- The corpus contains the tokens of reference string with IOB labels corresponding to metadata field types.
+- The file named as “automatic_inspection_data(train_set).txt” was constructed through the fully automatic inspection process. It contains a total of 3,680,620 labeled references, and was used as training set for training our BERT-based parsing model in our study.
+- The file named as “manual_insepction_data_(validation_set).txt” was developed through the manual inspection process by several annotators. It contains a total of 63,878 labeled references, and was used as validation set.
+- The file named as “manual_inspection_data_(test_set).txt” was built through the manual inspection process. It contains a total of 71,489 labeled references, and was used as test set.
+In the files, each reference is separated by a newline character. In each first line of references, a unique identifier and language type are listed.
