 ### Description
 
-This is the project to create a dataset for grounding of formulae.

-The original XHTML file of the paper was taken from the [arXMLiv:08.2018
-dataset](/resources/arxmliv-dataset-082018/), and we manually annotated all
-937 identifiers (i.e., `<mi>` tags) in the document to the corresponding

+This dataset is a ground truth of formula grounding annotation data for 15
+scientific papers. More specifically, a total of 12,352 math identifiers were
+annotated with their referring mathematical concepts, explicitly indicating
+coreference relations within each article. A total of 938 text spans, called
+grounding sources, that were used as the basis for human grounding were

 The annotation is performed with our open-source annotation tool
