Knowledge-enabled BERT for aspect-based sentiment analysis

作者：

Highlights：

• External knowledge is used for improving the performance of aspect based sentiment analysis.

• We study the problem of explainable aspect-based sentiment analysis by leveraging a sentiment knowledge graph to better capture the sentiment relations between aspects and sentiment terms.

• We propose incorporating external knowledge into the BERT to obtain the embedding vectors for aspect based sentiment analysis.
