# The CoreSearch Dataset
A large-scale dataset for cross-document event coreference **search**</br>
- **Paper:** [Cross-document Event Coreference Search: Task, Dataset and Modeling](https://arxiv.org/abs/2210.12654)
- **<ins>CoreSearchV2:</ins>** A cleaner version of this dataset is now available at [https://huggingface.co/datasets/biu-nlp/CoreSearchV2](https://huggingface.co/datasets/biu-nlp/CoreSearchV2)
### Languages
English
## Load Dataset
You can read/download the dataset files following Huggingface Hub instructions.</br>
For example, below code will load CoreSearch DPR folder:
```python
from huggingface_hub import hf_hub_url, cached_download
import json
REPO_ID = "datasets/Intel/CoreSearch"
DPR_FILES = "/dpr/"
dpr_files = ["dpr/Dev.json", "dpr/Train.json", "dpr/Test.json"]
dpr_jsons = list()
for _file in dpr_files:
dpr_jsons.append(json.load(open(cached_download(
hf_hub_url(REPO_ID, _file)), "r")))
```

abstract = "The task of Cross-document Coreference Resolution has been traditionally formulated as requiring to identify all coreference links across a given set of documents. We propose an appealing, and often more applicable, complementary set up for the task {--} Cross-document Coreference Search, focusing in this paper on event coreference. Concretely, given a mention in context of an event of interest, considered as a query, the task is to find all coreferring mentions for the query event in a large document collection. To support research on this task, we create a corresponding dataset, which is derived from Wikipedia while leveraging annotations in the available Wikipedia Event Coreferecene dataset (WEC-Eng). Observing that the coreference search setup is largely analogous to the setting of Open Domain Question Answering, we adapt the prominent Deep Passage Retrieval (DPR) model to our setting, as an appealing baseline. Finally, we present a novel model that integrates a powerful coreference scoring scheme into the DPR architecture, yielding improved performance.",
