abstract
= {Aspect-based sentiment analysis (ABSA) is a fast-growing research
area in natural language processing (NLP) that provides more
fine-grained information, considering the aspect as the fundamental
item. The ABSA primarily measures sentiment towards a given aspect, but
does not quantify the intensity of that sentiment. For example,
intensity of positive sentiment expressed for service in service is good
is comparatively weaker than in service is excellent. Thus, aspect
sentiment intensity will assist the stakeholders in mining user
preferences more precisely. Our current work introduces a novel task
called aspect based sentiment intensity analysis (ABSIA) that
facilitates research in this direction. An annotated review corpus for
ABSIA is introduced by labelling the benchmark SemEval ABSA restaurant
dataset with the seven (7) classes in a semi-supervised way. To
demonstrate the effective usage of corpus, we cast ABSIA as a natural
language generation task, where a natural sentence is generated to
represent the output in order to utilize the pre-trained language models
effectively. Further, we propose an effective technique for the joint
learning where ABSA is used as a secondary task to assist the primary
task, i.e. ABSIA. An improvement of 2 points is observed over the single
task intensity model. To explain the actual decision process of the
proposed framework, model explainability technique is employed that
extracts the important opinion terms responsible for generation (Source
code and the dataset has been made available on , )},
