- Abstract: As an important fine-grained sentiment analysis problem, aspect-based
sentiment analysis (ABSA), aiming to analyze and understand people's opinions
at the aspect level, has been attracting considerable interest in the last
decade. To handle ABSA in different scenarios, various tasks have been
introduced for analyzing different sentiment elements and their relations,
including the aspect term, aspect category, opinion term, and sentiment
polarity. Unlike early ABSA works focusing on a single sentiment element, many
compound ABSA tasks involving multiple elements have been studied in recent
years for capturing more complete aspect-level sentiment information. However,
a systematic review of various ABSA tasks and their corresponding solutions is
still lacking, which we aim to fill in this survey. More specifically, we
provide a new taxonomy for ABSA which organizes existing studies from the axes
of concerned sentiment elements, with an emphasis on recent advances of
compound ABSA tasks. From the perspective of solutions, we summarize the
utilization of pre-trained language models for ABSA, which improved the
performance of ABSA to a new stage. Besides, techniques for building more
practical ABSA systems in cross-domain/lingual scenarios are discussed.
Finally, we review some emerging topics and discuss some open challenges to
outlook potential future directions of ABSA.

This research presents a novel task, Review-Level Opinion Aspect Sentiment Target (ROAST)
ROAST seeks to close the gap between sentence-level and text-level ABSA by identifying every ABSA constituent at the review level.
We extend the available datasets to enable ROAST, addressing the drawbacks noted in previous research.

Aspect-based sentiment analysis (ABSA) is a fine-grained type of sentiment analysis that identifies aspects and their associated opinions from a text.
With the surge of digital opinionated text data, ABSA gained increasing popularity for its ability to mine more detailed and targeted insights.
This paper presents a systematic literature review of ABSA studies with a focus on trends and high-level relationships among these fundamental components.

Aspect-based sentiment analysis (ABSA) delves into understanding sentiments specific to distinct elements within a user-generated review.
We introduce the OATS dataset, which encompasses three fresh domains and consists of 27,470 sentence-level quadruples and 17,092 review-levels.
Our initiative seeks to bridge specific observed gaps: the recurrent focus on familiar domains like restaurants and laptops, limited data for intricate quadruple extraction tasks, and an occasional oversight of the synergy between sentence and review-level sentiments.
