Spider4SSC & S2CLite: A text-to-multi-query-language dataset using lightweight ontology-agnostic SPARQL to Cypher parser

TL;DR

This paper introduces S2CLite, a lightweight, rule-based parser that translates SPARQL to Cypher without external tools, significantly improving parsing accuracy and enabling a new unified text-to-query dataset.

Contribution

The paper presents S2CLite, a novel ontology-agnostic, rule-based parser for SPARQL to Cypher translation, and introduces the Spider4SSC dataset for multi-query language tasks.

Findings

S2CLite achieves 77.8% parsing accuracy on Spider4SPARQL.

S2CLite outperforms S2CTrans in execution accuracy (96.6%).

The Spider4SSC dataset contains 4525 questions with multi-query language equivalents.

Abstract

We present Spider4SSC dataset and S2CLite parsing tool. S2CLite is a lightweight, ontology-agnostic parser that translates SPARQL queries into Cypher queries, enabling both in-situ and large-scale SPARQL to Cypher translation. Unlike existing solutions, S2CLite is purely rule-based (inspired by traditional programming language compilers) and operates without requiring an RDF graph or external tools. Experiments conducted on the BSBM42 and Spider4SPARQL datasets show that S2CLite significantly reduces query parsing errors, achieving a total parsing accuracy of 77.8% on Spider4SPARQL compared to 44.2% by the state-of-the-art S2CTrans. Furthermore, S2CLite achieved a 96.6\% execution accuracy on the intersecting subset of queries parsed by both parsers, outperforming S2CTrans by 7.3%. We further use S2CLite to parse Spider4SPARQL queries to Cypher and generate Spider4SSC, a unified Text-to-Query language (SQL, SPARQL, Cypher) dataset with 4525 unique questions and 3 equivalent sets of 2581 matching queries (SQL, SPARQL and Cypher). We open-source S2CLite for further development on GitHub (github.com/vejvarm/S2CLite) and provide the clean Spider4SSC dataset for download.
