Abstract
Existing solutions do not work well when multi-targets coexist in a sentence.
The reason is that the existing solution is usually to separate multiple targets and process
them separately. If the original sentence has N target, the original sentence will be
repeated for N times, and only one target will be processed each time. To some extent,
this approach degenerates the fine-grained sentiment classification task into the sentencelevel sentiment classification task, and the research method of processing the target
separately ignores the internal relation and interaction between the targets. Based on the
above considerations, we proposes to use Graph Convolutional Network (GCN) to model
and process multi-targets appearing in sentences at the same time based on the positional
relationship, and then to construct a graph of the sentiment relationship between targets
based on the difference of the sentiment polarity between target words. In addition to the
standard target-dependent sentiment classification task, an auxiliary node relation
classification task is constructed. Experiments demonstrate that our model achieves new
comparable performance on the benchmark datasets: SemEval-2014 Task 4, i.e., reviews
for restaurants and laptops. Furthermore, the method of dividing the target words into
isolated individuals has disadvantages, and the multi-task learning model is beneficial to
enhance the feature extraction ability and expression ability of the model.
