Document Timestamping

Below are the evaluation datasets used in my 2012 published work on labeling documents with timestamps. I used the NYT section of the Gigaword Corpus, Fourth Edition (available from the LDC). The datasets ignore documents that are repeats of other documents in the corpus, and a training/development/test split is defined. Each file simply lists the document IDs in the three datasets.


Formal analysis can be found in the following publication. If you produce new evaluations on this dataset, please cite:

Data Format

Each file contains one document ID per line. They correspond to documents in the Gigaword Corpus, Fourth Edition.
