DIANN

If you are interested in participating, send us an email to diannibereval [at] gmail.com and we will reply you with detailed instructions for participation. All participants will be automatically subscribed to our mailing list. Information about the submission of results and their format will be available soon.
We invite potential participants to contact us, in order to be kept up to date with the latest news related to the task. The organizers will assist you for any potential issues that could be raised.

The dataset has been collected between 2017 and 2018. DIANN's corpus consists of a collection of 500 abstracts from Elsevier journal papers related to the biomedical domain. We have selected those abstracts for which there are available both, the Spanish and the English versions.
We have annotated the disabilities appearing in these abstracts using the XML tag <dis>. Disabilities are usually expressed either with a specific word, such as "blindness", or as the limitation or lack of a human function, such as "lack of vision".

• English:

Fragile-X syndrome is an inherited form of <dis>mental retardation</dis> with a connective tissue component involving mitral valve prolapse.

Age related macular degeneration (AMD) is the leading cause of <dis>blindness</dis> in individuals older than 65 years of age.

• Spanish:

El síndrome X frágil es una forma hereditaria de <dis>retraso mental</dis> con una afectación de tejido conectivo que produce prolapso de la válvula mitral.

La degeneración macular asociada a la edad (DMAE) constituye la causa principal de <dis>ceguera</dis> en personas mayores de 65 años.

The boundaries among diseases, disabilities and signs are often unclear. In order to clarify what have been considered a disability in the annotations for this task, we provide lists of disability terms and lists of functions whose absence or limitation has been considered a disability.

Functions Disabilities

Notice that these lists only include one representative term for each concept, but different variants of them can appear in the corpus. For example "sightlessness" does not appear because its representative term is "blindness". Functions can also appear in the corpus in a wide variety of forms. For example:

• English:
• Sight: One month later, she presented with complaints of systemic oedema and <dis>loss of vision </dis>.
• Spanish:
• Movilidad: Fampridina-LP a dosis de 10mg cada 12 h es actualmente el único fármaco autorizado para mejorar el <dis>trastorno de la marcha </dis> en adultos con EM.

The modifiers affecting the disability have been annoated as part of it.

Acronyms referring to a disability have been also annotated with the <dis> tag, but only if the extended version has also appeared in the same abstract.

• English:

To establish the validity and reliability of the Montreal Cognitive Assessment in Spanish (MoCA-S) to identify <dis>mild cognitive impairment</dis> (<dis>MCI</dis>)...

• Spanish:

Establecer la validez y confiabilidad del Montreal Evaluación Cognitiva en Español (MoCA-E) para identificar <dis>deterioro cognitivo leve</dis> (<dis>DCL</dis>)...

It is necessary to take into consideration that disabilities that appear isolated in texts without any context (e. g., search queries) or disabilities that appear in names of associations or entities (e. g., Care Unit for Dementia Patients) have not been annotated.

Negation is annotated when it affects one or more disabilities. We have adopted the criteria from the Bioscope corpus for annotating negation in English. For Spanish we have annotated the scope corresponding to the English annotation. Negation is annotated with the <scp> tag. For the sake of clarity, the negation triggers has also been annoted with the <neg> tag.

• English:

In the patients <scp><neg>without</neg> <dis>dementia</dis></scp>, significant differences were obtained in terms of functional and cognitive status (Barthel index of 52.34±38 and Pfeiffer test with an average score of 1.48 ±3.2 (P<.001)).

• Spanish:

En pacientes <scp> <neg>sin</neg> <dis>demencia</dis></scp>, se obtienen diferencias significativas en cuanto a la situación funcional y cognitiva (índice de Barthel de 52,34±38 y test de Pfeiffer con una puntuación media de 1,48±3,2 (p<0,001)).
