Dataset Card for CoNLL04

Dataset Summary

The CoNLL04 dataset is a benchmark dataset used for relation extraction tasks. It contains 1,437 sentences, each of which has at least one relation. The sentences are annotated with information about entities and their corresponding relation types. The data in this repository was converted from ConLL04 format to JSONL format in https://github.com/lavis-nlp/spert/blob/master/scripts/conversion/convert_conll04.py

The original data can be found here: https://cogcomp.seas.upenn.edu/page/resource_view/43

The sentences in this dataset are tokenized and are annotated with entities (Peop, Loc, Org, Other) and relations (Located_In, Work_For, OrgBased_In, Live_In, Kill).

Languages

The language in the dataset is English.
