Implicit sentiment analysis as a challenging branch of sentiment analysis tasks faces issues such as lacking explicit sentiment cues and complex text semantics. Inspired by CoT, this paper proposed the TPISA. This method combined large language models with local pre-trained models, employing multi-level reasoning to extract sentiment elements such as aspects and potential opinions, which enables to more easily infer the final sentiment polarity. In the first two levels, it leveraged the extensive world knowledge embedded in LLMs to augment the sentiment information of sentiment sentences. Subsequently, the aspects and potential opinions acquired from these initial levels are interconnected with the context, forming inputs for the third level prompt. Concurrently, it constructed sentiment label words to empower the pre-trained model to assimilate profound semantic insights from the labeled vocabulary, thereby enhancing the model's learning capacity. The experimental results demonstrate that the proposed model achieves improvements of 5. 65 and 6.72 percentage points on the SemEval14 Laptop and Restaurant datasets, respectively, compared to the state-of-the-art models, verifying the progressiveness of this method.
