The task of translating Natural Language Queries (NLQs) to Structured Query Language (SQL) in interfaces deployed in relational databases is a challenging one, and has been the subject of recent studies in the database community. Conventional rule-based systems utilize a pipeline of solutions to deal with each step of this task, including stop word filtering, tokenization, stemming/lemmatization, parsing, tagging, and translation. However, recent works have focused mainly on the translation step while overlooking earlier steps by using ad-hoc solutions. One of the most critical and challenging problems in this pipeline is keyword mapping - constructing a mapping between tokens in the query and relational database elements such as tables, attributes, values etc. To address this problem, the authors propose a novel deep learning-based supervised approach called DBTagger (DataBase Tagger), which utilizes POS tags of NLQs. They define the keyword mapping problem as a sequence tagging problem and use bi-directional recurrent neural networks for multi-task learning. The proposed approach is an end-to-end and schema-independent solution making it practical for various relational databases. The authors evaluate their approach on eight different datasets and report new state-of-the-art accuracy results with an average accuracy rate of 92.4%. Additionally, they demonstrate that DBTagger is faster than its counterparts up to 10000 times and scalable for bigger databases. Overall, this study presents an innovative solution to the challenging task of translating NLQs into SQL queries by proposing a novel deep learning-based approach that outperforms existing methods while being practical for various relational databases.

Translating Natural Language Queries to Structured Query Language: A Novel Deep Learning-Based Approach

The task of translating natural language queries (NLQs) into structured query language (SQL) for interfaces deployed in relational databases is a challenging one. Recent studies in the database community have focused mainly on the translation step, while overlooking earlier steps by using ad-hoc solutions. One of the most critical and challenging problems in this pipeline is keyword mapping - constructing a mapping between tokens in the query and relational database elements such as tables, attributes, values etc. To address this problem, researchers proposed a novel deep learning-based supervised approach called DBTagger (DataBase Tagger).

Background

Conventional rule-based systems utilize a pipeline of solutions to deal with each step of translating NLQs to SQL queries. This includes stop word filtering, tokenization, stemming/lemmatization, parsing, tagging and translation. However, these methods are limited by their reliance on handcrafted rules which can be difficult to maintain and prone to errors when dealing with complex queries or databases with large schemas.

DBTagger: A Novel Deep Learning-Based Approach

To address these issues, the authors propose DBTagger – an end-to-end deep learning based solution that utilizes POS tags from NLQs for keyword mapping. The authors define the keyword mapping problem as a sequence tagging problem and use bi-directional recurrent neural networks for multi-task learning. Additionally they demonstrate that DBTagger is faster than its counterparts up to 10000 times and scalable for bigger databases making it practical for various relational databases.

Evaluation Results

The authors evaluate their approach on eight different datasets and report new state-of-the art accuracy results with an average accuracy rate of 92.4%. This demonstrates that DBTagger outperforms existing methods while being practical for various relational databases.

Conclusion

In conclusion, this study presents an innovative solution to the challenging task of translating NLQs into SQL queries by proposing a novel deep learning based approach that outperforms existing methods while being practical for various relational databases
