Adaptive and Robust Translation from Natural Language to Multi-model Query Languages

Multi-model databases and polystore systems are increasingly studied for managing multimodel data holistically.As their primary interface, multi-model query languages (MMQLs) often exhibit complex grammars, highlighting the need for effective Text-to-MMQL translation methods.Despite advances in natural language translation, no effective solutions for Text-to-MMQL exist.To address this gap, we formally define the Text-to-MMQL task and present the first Text-to-MMQL dataset involving three representative MMQLs.We propose an adaptive Text-to-MMQL framework that includes both a schema embedding module for capturing multi-model schema information and an MMQL representation strategy to generate concise intermediate query formats with error correction in generated queries.Experimental results show that the proposed framework achieves over a 9% accuracy improvement over our adapted baseline methods.
