AttentionSiteDTI: an interpretable graph-based model for drug-target interaction prediction using NLP sentence-level relation classification

yazdanimehdi/AttentionSiteDTI Briefings in Bioinformatics 2022

In this study, we introduce an interpretable graph-based deep learning prediction model, AttentionSiteDTI, which utilizes protein binding sites along with a self-attention mechanism to address the problem of drug–target interaction prediction.

Enhancing Targeted Minority Class Prediction in Sentence-Level Relation Extraction

henry-paik/EnhancingREMC Sensors 2022

Sentence-level relation extraction (RE) has a highly imbalanced data distribution that about 80% of data are labeled as negative, i. e., no relation; and there exist minority classes (MC) among positive labels; furthermore, some of MC instances have an incorrect label.

Relation-Specific Attentions over Entity Mentions for Enhanced Document-Level Relation Extraction

fduyjx/rsman NAACL 2022

Compared with traditional sentence-level relation extraction, document-level relation extraction is a more challenging task where an entity in a document may be mentioned multiple times and associated with multiple relations.

Selecting Optimal Context Sentences for Event-Event Relation Extraction

hieumdt/SCS-EERE AAAI 2022

To achieve this goal, our work addresses the problems of subevent relation extraction (SRE) and temporal event relation extraction (TRE) that aim to predict subevent and temporal relations between two given event mentions/triggers in texts.
