Latent Opinions Transfer Network for Target-Oriented Opinion Words Extraction

Understand

Target-oriented opinion words extraction (TOWE) is a new subtask of ABSA, which aims to extract the corresponding opinion words for a given opinion target in a sentence.

• Recently, neural network methods have been applied to this task and achieve promising results.
• However, the difficulty of annotation causes the datasets of TOWE to be insufficient, which heavily limits the performance of neural models.
• By contrast, abundant review sentiment classification data are easily available at online review sites.
