摘要

摘要

En 中文
With the increase of unstructured text on social media platforms from user opinions, deep neural network techniques have significantly contributed to the aspect extraction subtask of Aspect-Based Sentiment Analysis (ABSA). In a multi-sentence review, sentences are contextually interdependent, and static word embedding generates similar representations for the same word in different domains. Hence, existing techniques cannot capture inter-sentence dependencies for valid multi-word aspect extraction. Further, incorporating conceptual information to associate the context and aspect terms is still a challenging task. Therefore, this paper aims to remove inadequate information and capture aspect co-referencing by adding a sentence coreference resolution step before performing ABSA in an unsupervised rule-based method. Next, domain irrelevant aspects are pruned out using contextual embedding. Furthermore, aspects extracted using unsupervised way are given as labeled in training the hierarchical attention-based network using pre-trained language model BERT, Bidirectional Encoder Representations from Transformers. The experimental results on the SemEval-16 dataset show that F-score results are between 2.5% and 5% better than recent supervised deep learning approaches for laptop and restaurant domains, respectively.
