|
| DDRND (Mafat) as part of the Israeli national NLP program (see our GitHub at https://nnlp-il.mafat.ai/#Our-Github) |
| and the Israeli Association of Human Language Technologies (https://www.iahlt.org) |
|
|
| ## Introduction |
|
|
| The coreference corpus is an extension of IAHLT's named entities dataset for |
| Hebrew and Arabic. This project is a work in progress, such that a subset of |
| articles (full-doc level) that are already annotated for entities are being |
| further annotated for (named) entity coreference. |
|
|
| The corpus consists of 1 apc articles from Youtube transcripts (0%); 201. |
| arb articles from the Kul al-Arab news organisation (96%), the All Rights. |
| entitlements organisation (0%), Weizmann popular science articles (2%);. |
| 657 heb articles from Bagatz court decisions (3%), Davar news organisation. |
| (75%), Israel Hayom news organisation (3%), Knesset protocols (1%),. |
| Weizmann popular science articles (4%), Hebrew Wikipedia entries (11%);. |
|
|
| The corpus, 1 paragraphs (apc), 2811 paragraphs (arb) and 9610 paragraphs |
| (heb), has been annotated with morpheme-level mention spans, assembled |
| into coreference clusters with entity types. |
|
|
| ## Data set |
|
|
| The current release includes the following files: |
|
|
| Annotated documents (.jsonl): |
|
|
| 1. data/coref-4-rc7-heb-all -- heb articles |
| 2. data/coref-4-rc7-heb-unique -- heb articles, each annotated once |
| 3. data/coref-4-rc7-heb-iaa -- heb articles, used for IAA |
|
|
| Additionally, all files are provided in a human-readable form (readable_data/*). |
| |
| ## Format |
| |
| Each article is a single json record. Some articles have been doubly-annotated |
| for the purposes of inter-annotator agreement study, their articles appear |
| multiple times. |
| |
| The jsonl structure is: |
| ``` |
| { text: str, |
| user: str, |
| metadata: { source: str, doc_id: str, ... }, |
| clusters: [ { |
| metadata: { name: str, entity: str }, |
| mentions: [ (int, int, dict) ] |
| } ] |
| } |
| ``` |
| |
| The `text` field contains the raw text of the original article. The top-level |
| `metadata` dictionary provides document-level metadata, minimally `source` and |
| `doc_id`. |
|
|
| The `clusters` field is a list of JSON cluster records each containing a |
| `metadata` and `mentions` field. The cluster-level `metadata` field has a name |
| for the cluster and its entity type. The `mentions` field is a list of triples: |
| the span indices of the text plus a metadata dictionary. We provide no |
| mention-level metadata in this release. |
|
|
| Not all clusters have been annotated for entity type; this will be completed in |
| a future release. |
