Dataset Summary

The dataset consists of 12 documents (9 for Spanish due to parsing errors) taken from EUR-Lex, a multilingual corpus of court decisions and legal dispositions in the 24 official languages of the European Union. The documents have been annotated for named entities following the guidelines of the MAPA project which foresees two annotation level, a general and a more fine-grained one. The annotated corpus can be used for named entity recognition/classification.

Supported Tasks and Leaderboards

The dataset supports the task of Named Entity Recognition and Classification (NERC).

Languages

The following languages are supported: bg, cs, da, de, el, en, es, et, fi, fr, ga, hu, it, lt, lv, mt, nl, pt, ro, sk, sv

Dataset Structure

Data Instances

The file format is jsonl and three data splits are present (train, validation and test). Named Entity annotations are non-overlapping.

Data Fields

For the annotation the documents have been split into sentences. The annotations has been done on the token level. The files contain the following data fields

• —language: language of the sentence
• —type: The document type of the sentence. Currently, only EUR-LEX is supported.
• —file_name: The document file name the sentence belongs to.
• —sentence_number: The number of the sentence inside its document.
• —tokens: The list of tokens in the sentence.
• —coarse_grained: The coarse-grained annotations for each token
• —fine_grained: The fine-grained annotations for each token

As previously stated, the annotation has been conducted on a global and a more fine-grained level.

The tagset used for the global and the fine-grained named entities is the following:

• —Address
• —Building
• —City
• —Country
• —Place
• —Postcode
• —Street
• —Territory
• —Amount
• —Unit
• —Value
• —Date
• —Year
• —Standard Abbreviation
• —Month
• —Day of the Week
• —Day
• —Calender Event
• —Person
• —Age
• —Email
• —Ethnic Category
• —Family Name
• —Financial
• —Given Name – Female
• —Given Name – Male
• —Health Insurance Number
• —ID Document Number
• —Initial Name
• —Marital Status
• —Medical Record Number
• —Nationality
• —Profession
• —Role
• —Social Security Number
• —Title
• —Url
• —Organisation
• —Time
• —Vehicle
• —Build Year
• —Colour
• —License Plate Number
• —Model
• —Type

The final coarse grained tagset (in IOB notation) is the following:

['O', 'B-ORGANISATION', 'I-ORGANISATION', 'B-ADDRESS', 'I-ADDRESS', 'B-DATE', 'I-DATE', 'B-PERSON', 'I-PERSON', 'B-AMOUNT', 'I-AMOUNT', 'B-TIME', 'I-TIME']

The final fine grained tagset (in IOB notation) is the following:

[ 'O', 'B-BUILDING', 'I-BUILDING', 'B-CITY', 'I-CITY', 'B-COUNTRY', 'I-COUNTRY', 'B-PLACE', 'I-PLACE', 'B-TERRITORY', 'I-TERRITORY', 'I-UNIT', 'B-UNIT', 'B-VALUE', 'I-VALUE', 'B-YEAR', 'I-YEAR', 'B-STANDARD ABBREVIATION', 'I-STANDARD ABBREVIATION', 'B-MONTH', 'I-MONTH', 'B-DAY', 'I-DAY', 'B-AGE', 'I-AGE', 'B-ETHNIC CATEGORY', 'I-ETHNIC CATEGORY', 'B-FAMILY NAME', 'I-FAMILY NAME', 'B-INITIAL NAME', 'I-INITIAL NAME', 'B-MARITAL STATUS', 'I-MARITAL STATUS', 'B-PROFESSION', 'I-PROFESSION', 'B-ROLE', 'I-ROLE', 'B-NATIONALITY', 'I-NATIONALITY', 'B-TITLE', 'I-TITLE', 'B-URL', 'I-URL', 'B-TYPE', 'I-TYPE', ]

Dataset Creation

Curation Rationale

„[…] to our knowledge, there exist no open resources annotated for NERC [Named Entity Recognition and Classificatio] in Spanish in the legal domain. With the present contribution, we intend to fill this gap. With the release of the created resources for fine-tuning and evaluation of sensitive entities detection in the legal domain, we expect to encourage the development of domain-adapted anonymisation tools for Spanish in this field“ (de Gibert Bonet et al., 2022)

Source Data

Initial Data Collection and Normalization

The dataset consists of documents taken from EUR-Lex corpus which is publicly available. No further information on the data collection process are given in de Gibert Bonet et al. (2022).

Who are the source language producers?

The source language producers are presumably lawyers.

Annotations

Annotation process

"The annotation scheme consists of a complex two level hierarchy adapted to the legal domain, it follows the scheme described in (Gianola et al., 2020) […] Level 1 entities refer to general categories (PERSON, DATE, TIME, ADDRESS...) and level 2 entities refer to more fine-grained subcategories (given name, personal name, day, year, month...). Eur-Lex, CPP and DE have been annotated following this annotation scheme […] The manual annotation was performed using INCePTION (Klie et al., 2018) by a sole annotator following the guidelines provided by the MAPA consortium." (de Gibert Bonet et al., 2022)

Who are the annotators?

Only one annotator conducted the annotation. More information are not provdided in de Gibert Bonet et al. (2022).

Other Known Limitations

Note that the dataset at hand presents only a small portion of a bigger corpus as described in de Gibert Bonet et al. (2022). At the time of writing only the annotated documents from the EUR-Lex corpus were available.

Note that the information given in this dataset card refer to the dataset version as provided by Joel Niklaus and Veton Matoshi. The dataset at hand is intended to be part of a bigger benchmark dataset. Creating a benchmark dataset consisting of several other datasets from different sources requires postprocessing. Therefore, the structure of the dataset at hand, including the folder structure, may differ considerably from the original dataset. In addition to that, differences with regard to dataset statistics as give in the respective papers can be expected. The reader is advised to have a look at the conversion script ``convert_to_hf_dataset.py`` in order to retrace the steps for converting the original dataset into the present jsonl-format. For further information on the original dataset structure, we refer to the bibliographical references and the original Github repositories and/or web pages provided in this dataset card.
