mRAT-SQL+GAP: A Portuguese Text-to-SQL Transformer [PDF]
, 2021 The translation of natural language questions to SQL queries has attracted growing attention, in particular in connection with transformers and similar language models. A large number of techniques are geared towards the English language; in this work, we thus investigated translation to SQL when input questions are given in the Portuguese language. To

Effect of semantic distance on learning structured query language: An empirical study
Frontiers in Psychology, 2022 Students of database courses usually encounter difficulties in learning structured query language (SQL). Numerous studies have been conducted to improve how students learn SQL. However, learning SQL remains difficult. This study analyzed the difficulties

An Efficient Algorithm for Optimizing Adaptive Quantum Metrology Processes
, 2011 Quantum-enhanced metrology infers an unknown quantity with accuracy beyond the standard quantum limit (SQL). Feedback-based metrological techniques are promising for beating the SQL but devising the feedback procedures is difficult and inefficient.

Relation-Aware Graph Transformer for SQL-to-Text Generation
Applied Sciences, 2021 Generating natural language descriptions for structured representation (e.g., a graph) is an important yet challenging task. In this work, we focus on SQL-to-text, a task that maps a SQL query into the corresponding natural language question.
