Adaptive Local Context and Syntactic Feature Modeling for Aspect-Based Sentiment Analysis

open access: yesApplied Sciences, 2023
Aspect-based sentiment analysis is a fine-grained sentiment analysis task that consists of two types of subtasks: aspect term extraction and aspect sentiment classification. In the aspect term extraction task, current methods suffer from the lack of fine-

Don’t Eclipse Your Arts Due to Small Discrepancies: Boundary Repositioning with a Pointer Network for Aspect Extraction

open access: yesAnnual Meeting of the Association for Computational Linguistics, 2020
The current aspect extraction methods suffer from boundary errors. In general, these errors lead to a relatively minor difference between the extracted aspects and the ground-truth. However, they hurt the performance severely.

An illustrative example of refactoring object-oriented source code with aspect-oriented mechanisms [PDF]

open access: yes, 2008
This paper describes a refactoring process that transforms a Java source code base into a functionally equivalent AspectJ source code base. The process illustrates the use of a collection of refactorings for aspect-oriented source code, covering the ...
