VoIDext: Vocabulary and Patterns for Enhancing Interoperable Datasets with Virtual Links

1 code implementation5 Jun 2019 Tarcisio Mendes de Farias, Kurt Stockinger, Christophe Dessimoz

Semantic heterogeneity remains a problem when interoperating with data from sources of different scopes and knowledge domains.

A Comparative Survey of Recent Natural Language Interfaces for Databases

no code implementations21 Jun 2019 Katrin Affolter, Kurt Stockinger, Abraham Bernstein

Each of the systems is evaluated using a curated list of ten sample questions to show their strengths and weaknesses.

Join Query Optimization with Deep Reinforcement Learning Algorithms

1 code implementation26 Nov 2019 Jonas Heitz, Kurt Stockinger

The main idea of FOOP is to use a data-adaptive learning query optimizer that avoids exhaustive enumerations of join orders and is thus significantly faster than traditional approaches based on dynamic programming.

ValueNet: A Natural Language-to-SQL System that Learns from Database Information

2 code implementations29 May 2020 Ursin Brunner, Kurt Stockinger

In this paper we propose ValueNet light and ValueNet -- two end-to-end NL-to-SQL systems that incorporate values using the challenging Spider dataset.

Multiple Query Optimization using a Hybrid Approach of Classical and Quantum Computing

1 code implementation22 Jul 2021 Tobias Fankhauser, Marc E. Solèr, Rudolf M. Füchslin, Kurt Stockinger

Our experimental results demonstrate that our algorithm currently can only handle small problem sizes due to the limited number of qubits available on a gate-based quantum computer compared to a quantum computer based on quantum annealing.

ScienceBenchmark: A Complex Real-World Benchmark for Evaluating Natural Language to SQL Systems

no code implementations7 Jun 2023 Yi Zhang, Jan Deriu, George Katsogiannis-Meimarakis, Catherine Kosten, Georgia Koutrika, Kurt Stockinger

Thus, the challenge is many-fold: creating NL-to-SQL systems for highly complex domains with a small amount of hand-made training data augmented with synthetic data.

Data-Driven Information Extraction and Enrichment of Molecular Profiling Data for Cancer Cell Lines

1 code implementation3 Jul 2023 Ellery Smith, Rahel Paloots, Dimitris Giagkos, Michael Baudis, Kurt Stockinger

This system extracts deep semantic relations between textual entities from scientific literature to enrich existing structured clinical data in the domain of cancer cell lines.

Spider4SPARQL: A Complex Benchmark for Evaluating Knowledge Graph Question Answering Systems

1 code implementation28 Sep 2023 Catherine Kosten, Philippe Cudré-Mauroux, Kurt Stockinger

With the recent spike in the number and availability of Large Language Models (LLMs), it has become increasingly important to provide large and realistic benchmarks for evaluating Knowledge Graph Question Answering (KGQA) systems.
