The task of answering natural language questions over RDF data has received wide interest in recent years, in particular in the context of the series of QALD benchmarks. The task consists of mapping a natural language question to an executable form, e.g. SPARQL, so that answers from a given KB can be extracted. So far, most systems proposed are i) monolingual and ii) rely on a set of hard-coded rules to interpret questions and map them into a SPARQL query. We present the first multilingual QALD pipeline that induces a model from training data for mapping a natural language question into logical form as probabilistic inference. In particular, our approach learns to map universal syntactic dependency representations to a language-independent logical form based on DUDES (Dependency-based Underspecified Discourse Representation Structures) that are then mapped to a SPARQL query as a deterministic second step. Our model builds on factor graphs that rely on features extracted from the dependency graph and corresponding semantic representations. We rely on approximate inference techniques, Markov Chain Monte Carlo methods in particular, as well as Sample Rank to update parameters using a ranking objective. Our focus lies on developing methods that overcome the lexical gap and present a novel combination of machine translation and word embedding approaches for this purpose. As a proof of concept for our approach, we evaluate our approach on the QALD-6 datasets for English, German & Spanish.

语义解析是自然语言处理的一项重要任务。然而,越南语在这一研究领域是一种低资源语言。在本文中,我们提出了第一个公共的大规模文本到SQL语义解析数据集越南。我们扩展并评估了两个强大的语义解析基线EditSQL(Zhang等人,2019)和IRNet(Guo et al.,2019年,在我们的数据集上。我们比较了两个基线的关键配置,发现:自动越南语分词提高了两个基线的分析结果;归一化逐点互信息(NPMI)得分(Bouma,2009)是有用的模式链接;潜在的句法特征提取的神经依赖分析越南语也改善了结果;用于越南语的单语语言模型PhoBERT(Nguyen和Nguyen,2020)有助于产生比最近最好的多语言语言模型XLM-R(Conneau等人,2020年)。
