A disambiguation method for potential ambiguities in Chinese based on knowledge graphs and large language model

Abstract

Traditional disambiguation methods struggle to effectively balance and integrate a wide range of contextual information and world knowledge when dealing with potential ambiguities in Chinese. To address this issue, this paper proposes a disambiguation model that integrates knowledge graphs and large language models (LLMs) to tackle lexical ambiguity in Chinese texts. This article uses an attention based disambiguation model, which is fine-tuned using multiple hyperparameter configurations. It optimizes network layers and knowledge graph embedding dimensions to enhance performance. Visualization of the attention mechanism reveals the model's focus on target words, context, and knowledge graph entities. Experiments conducted on a dataset comprising 200,000 sentences demonstrate significant improvements in accuracy and F1 scores, reaching 92.4 % and 91.9 %, respectively, compared to traditional statistical and deep learning models. Visualization of the attention mechanism reveals the model's focus on target words, context, and knowledge graph entities. The findings suggest that integrating knowledge graphs with LLMs offers an innovative approach to complex language tasks. In practical applications such as machine translation and chatbots, this model is expected to enhance both performance and interpretability.
