Methodology for Automatic Ontology Generation Using Database Schema Information [PDF]
Mobile Information Systems, 2018 An ontology is a model language that supports the functions to integrate conceptually distributed domain knowledge and infer relationships among the concepts. Ontologies are developed based on the target domain knowledge.

Proton: Probing Schema Linking Information from Pre-trained Language Models for Text-to-SQL Parsing [PDF]
Knowledge Discovery and Data Mining, 2022 The importance of building text-to-SQL parsers which can be applied to new databases has long been acknowledged, and a critical step to achieve this goal is schema linking, i.e., properly recognizing mentions of unseen columns or tables when generating ...

Stress leads to aberrant hippocampal involvement when processing schema-related information [PDF]
Learning & memory (Cold Spring Harbor, N.Y.), 2017 Prior knowledge, represented as a mental schema, has critical impact on how we organize, interpret, and process incoming information. Recent findings indicate that the use of an existing schema is coordinated by the medial prefrontal cortex (mPFC ...

Open-Domain Hierarchical Event Schema Induction by Incremental Prompting and Verification [PDF]
Annual Meeting of the Association for Computational Linguistics, 2023 Event schemas are a form of world knowledge about the typical progression of events. Recent methods for event schema induction use information extraction systems to construct a large number of event graph instances from documents, and then learn to ...

Semantic Enhanced Text-to-SQL Parsing via Iteratively Learning Schema Linking Graph [PDF]
Knowledge Discovery and Data Mining, 2022 The generalizability to new databases is of vital importance to Text-to-SQL systems which aim to parse human utterances into SQL statements. Existing works achieve this goal by leveraging the exact matching method to identify the lexical matching between

Network Schema Preserving Heterogeneous Information Network Embedding
International Joint Conference on Artificial Intelligence, 2020 As heterogeneous networks have become increasingly ubiquitous, Heterogeneous Information Network (HIN) embedding, aiming to project nodes into a low-dimensional space while preserving the heterogeneous structure, has drawn increasing attention in recent ...

Unified Structure Generation for Universal Information Extraction [PDF]
Annual Meeting of the Association for Computational Linguistics, 2022 Information extraction suffers from its varying targets, heterogeneous structures, and demand-specific schemas. In this paper, we propose a unified text-to-structure generation framework, namely UIE, which can universally model different IE tasks ...

Preview, Attend and Review: Schema-Aware Curriculum Learning for Multi-Domain Dialogue State Tracking [PDF]
Annual Meeting of the Association for Computational Linguistics, 2021 Existing dialog state tracking (DST) models are trained with dialog data in a random order, neglecting rich structural information in a dataset. In this paper, we propose to use curriculum learning (CL) to better leverage both the curriculum structure ...

Journal of Neurodevelopmental Disorders, 2021 Background Conceptual knowledge frameworks termed schemas facilitate memory formation and are posited to support flexible behavior. In adults, the medial temporal lobe (MTL) and medial prefrontal cortex (mPFC) trade-off in supporting schema-based memory ...
