The Impact of Schema Representation in the Text2Cypher Task

The impact of schema representation in the Text2Cypher task is a crucial aspect of natural language-to-Cypher query translation. The use of different schema formats can significantly influence performance, with complex schemas posing challenges for large language models (LLMs). Schema linking and filtering techniques have been explored to address these challenges, with various approaches including exact-match, similarity-based matching, and named entity recognition (NER) masking. Experimental results show that pruning schema lengths can lead to significant cost reductions and improved performance, with the best approach being Pruned By Exact-Match Schema. Further exploration of schema filtering methods is recommended for specific datasets or practical applications, and additional research is needed to determine the effectiveness of these approaches on a range of LLM models.
