Description

Aspect-based sentiment analysis (ABSA) is the task of identifying fine-grained opinion polarity towards specific aspects associated with a given target.
The goal of this internship is exploring and implementing a new neural architecture for end-to-end ABSA, where term detection, aspect and polarity classification are jointly modeled. Special attention will be given to data-efficient methods in order to cope with situations where little amount of annotated data is available. Experiments will be conducted and evaluated on multiple datasets from various domains and languages and results will be evaluated not only on specific ABSA subtasks but also on the full chain of annotations.

The expected outcome is, a minima, a multilingual prototype working on different domains.

The successful candidate should be enrolled in a graduate program, at the Master or PhD level, with a focus on NLP and Deep Learning.
Publication of results in major conferences/journals will be strongly encouraged.

Required skills

Good programming skills and proficiency with TensorFlow or PyTorch
