Approximate Nearest Neighbour Extraction Techniques and Neural Networks for Suicide Risk Prediction in the CLPsych 2022 Shared Task

no code implementations NAACL (CLPsych) 2022 Hermenegildo Fabregat Marcos, Ander Cejudo, Juan Martinez-Romo, Alicia Perez, Lourdes Araujo, Nuria Lebea, Maite Oronoz, Arantza Casillas

This paper describes the participation of our group on the CLPsych 2022 shared task. For task A, which tries to capture changes in mood over time, we have applied an Approximate Nearest Neighbour (ANN) extraction technique with the aim of relabelling the user messages according to their proximity, based on the representation of these messages in a vector space.

On the Contribution of Per-ICD Attention Mechanisms to Classify Health Records in Languages with Fewer Resources than English

2 code implementations RANLP 2021 Alberto Blanco, Sonja Remmer, Alicia Pérez, Hercules Dalianis, Arantza Casillas

We introduce a multi-label text classifier with per-label attention for the classification of Electronic Health Records according to the International Classification of Diseases.

Fully unsupervised low-dimensional representation of adverse drug reaction events through distributional semantics

no code implementations WS 2016 Alicia P{\'e}rez, Arantza Casillas, Koldo Gojenola

In brief, the ADRs are represented as vectors that link the drug with the disease in their context through a recursive additive model.

The impact of simple feature engineering in multilingual medical NER
