Dataset Card for NorNE: Norwegian Named Entities

Dataset Summary

NorNE is a manually annotated corpus of named entities which extends the annotation of the existing Norwegian Dependency Treebank. Comprising both of the official standards of written Norwegian (Bokmål and Nynorsk), the corpus contains around 600,000 tokens and annotates a rich set of entity types including persons,organizations, locations, geo-political entities, products, and events, in addition to a class corresponding to nominals derived from names.

There are 3 main configs in this dataset each with 3 versions of the NER tag set. When accessing the bokmaal, nynorsk, or combined configs the NER tag set will be comprised of 9 tags: GPE_ORG, GPE_LOC, ORG, LOC, PER, PROD, EVT, DRV, and MISC. The two special types GPE_LOC and GPE_ORG can easily be altered depending on the task, choosing either the more general GPE tag or the more specific LOC/ORG tags, conflating them with the other annotations of the same type. To access these reduced versions of the dataset, you can use the configs bokmaal-7, nynorsk-7, combined-7 for the NER tag set with 7 tags ( ORG, LOC, PER, PROD, EVT, DRV, MISC), and bokmaal-8, nynorsk-8, combined-8 for the NER tag set with 8 tags (LOC_ and ORG_: ORG, LOC, GPE, PER, PROD, EVT, DRV, MISC). By default, the full set (9 tags) will be used. See Annotations for further details.

Supported Tasks and Leaderboards

NorNE ads named entity annotations on top of the Norwegian Dependency Treebank.

Languages

Both Norwegian Bokmål (bokmaal) and Nynorsk (nynorsk) are supported as different configs in this dataset. An extra config for the combined languages is also included (combined). See the Annotation section for details on accessing reduced tag sets for the NER feature.

Dataset Structure

Each entry contains text sentences, their language, identifiers, tokens, lemmas, and corresponding NER and POS tag lists.

Data Instances

An example of the train split of the bokmaal config.

{'idx': '000001',
 'lang': 'bokmaal',
 'lemmas': ['lam', 'og', 'piggvar', 'på', 'bryllupsmeny'],
 'ner_tags': [0, 0, 0, 0, 0],
 'pos_tags': [0, 9, 0, 5, 0],
 'text': 'Lam og piggvar på bryllupsmenyen',
 'tokens': ['Lam', 'og', 'piggvar', 'på', 'bryllupsmenyen']}

Data Fields

Each entry is annotated with the next fields:

  • idx (int), text (sentence) identifier from the NorNE dataset
  • lang (str), language variety, either bokmaal, nynorsk or combined
  • text (str), plain text
  • tokens (List[str]), list of tokens extracted from text
  • lemmas (List[str]), list of lemmas extracted from tokens
  • ner_tags (List[int]), list of numeric NER tags for each token in tokens
  • pos_tags (List[int]), list of numeric PoS tags for each token in tokens

An example DataFrame obtained from the dataset:

idx lang text tokens lemmas ner_tags pos_tags

Dataset Creation

Curation Rationale

  1. A name in this context is close to Saul Kripke's definition of a name, in that a name has a unique reference and its meaning is constant (there are exceptions in the annotations, e.g. "Regjeringen" (en. "Government")).
  2. It is the usage of a name that determines the entity type, not the default/literal sense of the name,
  3. If there is an ambiguity in the type/sense of a name, then the the default/literal sense of the name is chosen (following Markert and Nissim, 2002).

For more details, see the "Annotation Guidelines.pdf" distributed with the corpus.

Source Data

Data was collected using blogs and newspapers in Norwegian, as well as parliament speeches and governamental reports.

Initial Data Collection and Normalization

The texts in the Norwegian Dependency Treebank (NDT) are manually annotated with morphological features, syntactic functions and hierarchical structure. The formalism used for the syntactic annotation is dependency grammar.

The treebanks consists of two parts, one part in Norwegian Bokmål (nob) and one part in Norwegian Nynorsk (nno). Both parts contain around 300.000 tokens, and are a mix of different non-fictional genres.

See the NDT webpage for more details.

Annotations

The following types of entities are annotated:

  • Person (PER): Real or fictional characters and animals
  • Organization (ORG): Any collection of people, such as firms, institutions, organizations, music groups, sports teams, unions, political parties etc.
  • Location (LOC): Geographical places, buildings and facilities
  • Geo-political entity (GPE): Geographical regions defined by political and/or social groups. A GPE entity subsumes and does not distinguish between a nation, its region, its government, or its people
  • Product (PROD): Artificially produced entities are regarded products. This may include more abstract entities, such as speeches, radio shows, programming languages, contracts, laws and ideas.
  • Event (EVT): Festivals, cultural events, sports events, weather phenomena, wars, etc. Events are bounded in time and space.
  • Derived (DRV): Words (and phrases?) that are dervied from a name, but not a name in themselves. They typically contain a full name and are capitalized, but are not proper nouns. Examples (fictive) are "Brann-treneren" ("the Brann coach") or "Oslo-mannen" ("the man from Oslo").
  • Miscellaneous (MISC): Names that do not belong in the other categories. Examples are animals species and names of medical conditions. Entities that are manufactured or produced are of type Products, whereas thing naturally or spontaneously occurring are of type Miscellaneous.

Furthermore, all GPE entities are additionally sub-categorized as being either ORG or LOC, with the two annotation levels separated by an underscore:

  • GPE_LOC: Geo-political entity, with a locative sense (e.g. "John lives in Spain")
  • GPE_ORG: Geo-political entity, with an organisation sense (e.g. "Spain declined to meet with Belgium")

The two special types GPE_LOC and GPE_ORG can easily be altered depending on the task, choosing either the more general GPE tag or the more specific LOC/ORG tags, conflating them with the other annotations of the same type. This means that the following sets of entity types can be derived:

  • 7 types, deleting _GPE: ORG, LOC, PER, PROD, EVT, DRV, MISC
  • 8 types, deleting LOC_ and ORG_: ORG, LOC, GPE, PER, PROD, EVT, DRV, MISC
  • 9 types, keeping all types: ORG, LOC, GPE_LOC, GPE_ORG, PER, PROD, EVT, DRV, MISC

The class distribution is as follows, broken down across the data splits of the UD version of NDT, and sorted by total counts (i.e. the number of examples, not tokens within the spans of the annotatons):

Type Train Dev Test Total
PER 4033 607 560 5200
ORG 2828 400 283 3511
GPE_LOC 2132 258 257 2647
PROD 671 162 71 904
LOC 613 109 103 825
GPE_ORG 388 55 50 493
DRV 519 77 48 644
EVT 131 9 5 145
MISC 8 0 0 0

To access these reduced versions of the dataset, you can use the configs bokmaal-7, nynorsk-7, combined-7 for the NER tag set with 7 tags ( ORG, LOC, PER, PROD, EVT, DRV, MISC), and bokmaal-8, nynorsk-8, combined-8 for the NER tag set with 8 tags (LOC_ and ORG_: ORG, LOC, GPE, PER, PROD, EVT, DRV, MISC). By default, the full set (9 tags) will be used.
