# Hungarian named entity recognition model with OntoNotes5 + more entity types

  - Pretrained model used: SZTAKI-HLT/hubert-base-cc 
  - Finetuned on NerKor+CARS-ONPP Corpus
  	
## Limitations

- max_seq_length = 448

## Training data

The underlying corpus, [NerKor+CARS-OntoNotes++](https://github.com/ppke-nlpg/NYTK-NerKor-Cars-OntoNotesPP), was derived from [NYTK-NerKor](https://github.com/nytud/NYTK-NerKor), a Hungarian gold standard named entity annotated corpus containing about 1 million tokens. 
It includes a small addition of 12k tokens of text (individual sentences) concerning motor vehicles (cars, buses, motorcycles) from the news archive of [hvg.hu](hvg.hu).
While the annotation in NYTK-NerKor followed the CoNLL2002 labelling standard with just four NE categories (`PER`, `LOC`, `MISC`, `ORG`), this version of the corpus features over 30 entity types, including all entity types used in the [OntoNotes 5.0] English NER annotation.
The new annotation elaborates on subtypes of the `LOC` and `MISC` entity types, and includes annotation for non-names like times and dates, quantities, languages and nationalities or religious or political groups. The annotation was elaborated with further entity subtypes not present in the Ontonotes 5 annotation (see below).

## Tags derived from the OntoNotes 5.0 annotation

Names are annotated according to the following set of types:

| | | 
|---|---------|
|`PER` | = PERSON People, including fictional |
|`FAC` | = FACILITY Buildings, airports, highways, bridges, etc. |
|`ORG` | = ORGANIZATION Companies, agencies, institutions, etc. |
|`GPE` | Geopolitical entites: countries, cities, states |
|`LOC` | = LOCATION Non-GPE locations, mountain ranges, bodies of water |
|`PROD` | = PRODUCT Vehicles, weapons, foods, etc. (Not services) |
|`EVENT` | Named hurricanes, battles, wars, sports events, etc. |
|`WORK_OF_ART` | Titles of books, songs, etc. |
|`LAW` | Named documents made into laws  |

The following are also annotated in a style similar to names:

| | | 
|---|---------|
| `NORP` | Nationalities or religious or political groups |
| `LANGUAGE` | Any named language |
| `DATE` | Absolute or relative dates or periods |
| `TIME` | Times smaller than a day |
| `PERCENT` | Percentage (including "%") |
| `MONEY` | Monetary values, including unit |
| `QUANTITY` | Measurements, as of weight or distance |
| `ORDINAL` | "first", "second" |
| `CARDINAL` | Numerals that do not fall under another type |

## Additional tags (not in OntoNotes 5)
Further subtypes of names of type `MISC`:

| | |
|-|-|
|`AWARD`| Awards and prizes |
| `CAR` | Cars and other motor vehicles |
|`MEDIA`| Media outlets, TV channels, news portals|
|`SMEDIA`| Social media platforms|
|`PROJ`| Projects and initiatives |
|`MISC`| Unresolved subtypes of MISC entities |
|`MISC-ORG`| Organization-like unresolved subtypes of MISC entities |

Further non-name entities:

| | |
|-|-|
|`DUR` |Time duration
|`AGE` |Age
|`ID`| Identifier
