Columns Property Annotation

4 papers with code • 3 benchmarks • 3 datasets

Column Property Annotation (CPA) refers to the task of predicting the semantic relation between two columns and is a subtask of Table Annotation. The input of a CPA problem is most commonly a pair of columns, but can also be only one column. The labels used in CPA are properties from vocabularies. Some examples are name, price, datePublished etc.

CPA is usually a multi-class classification problem and is also referred to as column relation annotation or relation extraction in different works.
