Table Column Annotation Benchmarks (CTA/CPA) for REVEAL

This dataset repository accompanies the paper:

Retrieve-and-Verify: A Table Context Selection Framework for Accurate Column Annotations
Zhihao Ding, Yongkang Sun, Jieming Shi. Proc. ACM Manag. Data (Dec 2025).

The work targets two column annotation tasks:

• Column Type Annotation (CTA): assign a semantic type to a target column.
• Column Property Annotation (CPA) (a.k.a. column relation/property annotation): assign a semantic relation/property between a target column and another column.

What is included in this Hugging Face dataset repository?

• GitTablesDB (gt-semtab22-dbpedia-all): raw CSV tables with 5-fold splits.
• GitTablesSC (gt-semtab22-schema-property-all): raw CSV tables with 5-fold splits.

Data schema (columns)

Column	Type	Description
table_id	string	Identifier of the source table.
column_id	int	0-based index of the target column within the table.
label	string	Ground-truth type id. For multi-class tasks, a single type ID (-1 indicates unlabeled). For multi-label tasks, a binary list encoded as a string (e.g., [1,0,0,...]).
data	string	Cell values of the target column in original order, serialized as a single string.
