Abstract: Highlights•Extract explicit data in ABSA task is crucial for multiple aspects.•Dependency tree neglects explicit data when exploring multi-aspects with diverse polarity.•Our parsimonious dual-filtration APS module filters the aspect-specific explicit data.•The integration of sentiment analyzer in APS interpreting complex sentiment expressions.•Concatenation of APS with AGCN propose a multi-view explicit representation learning.
