Dataset for Named Entity Recognition and Entity Linking from Greek Wikipedia Events

An automated benchmark dataset for (Named Entity Recognition) NER and (Named Entity Linking) NEL tools, based on Greek Wikipedia events pages.

Note: This data includes data from the following sources:
- Wikipedia el.wikipedia.org

Description

The dataset is provided in the form of  three  JSON-formatted subsets i.e.,  train, validation and test in an analogy of 70-20-10. The current version of the dataset contains 18,617 events annotated with 40,798 entity mentions and 36,189 links to elWikipedia (and wikidata ids). The dataset contains annotations belonging to 8 entity types: person, organization, location, gpe, event, facility, product and work of art.

Example

A record example is given below.

{

"json_file": "February 2012_39_0 events",
"text": "Sudan and South Sudan sign non-aggression pact.",
"ground_truth_mentions": [
      {"start": 0, "end": 4, "surface_mention": "Sudan", "mention_type": "GPE"},
      {"start": 10, "end": 20, "surface_mention": "South Sudan", "mention_type": "GPE"}
                                          ],
"ground_truth_links": [
      {"enwiki": "Sudan","wikidata": "Q1049"},
      {"enwiki": "South_Sudan", "wikidata": "Q958"}
                                         ]
}
