Schema Matching with Large Language Models: an Experimental Study

VLDB Workshops
Large Language Models (LLMs) have shown useful applications in a variety of tasks, including data wrangling. In this paper, we investigate the use of an off-the-shelf LLM for schema matching.

Representing Fuzzy Information by Using XML Schema

2008 19th International Conference on Database and Expert Systems Applications, 2008
Issues related to fuzzy data have been investigated in the classical database research field, and in the last years are becoming interesting topics also in the XML data context. In this work we propose a general XML schema definition for representing fuzzy information.

Visualization schemas for flexible information visualization

IEEE Symposium on Information Visualization, 2002. INFOVIS 2002., 2003
Relational databases provide significant flexibility to organize, store, and manipulate an infinite variety of complex data collections. This flexibility is enabled by the concept of relational data schemas, which allow data owners to easily design custom databases according to their unique needs. However, user interfaces and information visualizations

Automatic Ontology Generation Using Schema Information

2006 IEEE/WIC/ACM International Conference on Web Intelligence (WI 2006 Main Conference Proceedings)(WI'06), 2006
This paper discusses the automatic ontology generation process in a digital library. Traditional automatic ontology generation uses hierarchical clustering to group similar terms, and the result hierarchy is usually not satisfactory for human?s recognition.

KnowCoder: Coding Structured Knowledge into LLMs for Universal Information Extraction

Annual Meeting of the Association for Computational Linguistics
In this paper, we propose KnowCoder, a Large Language Model (LLM) to conduct Universal Information Extraction (UIE) via code generation. KnowCoder aims to develop a kind of unified schema representation that LLMs can easily understand and an effective ...

Schema Evolution in Federated Information Systems

2001
Mediators—used in federated information systems—provide a homogeneous read-only access to a set of autonomous information sources. To achieve semantic integration of the heterogeneous data, correspondences between the autonomous schemas are specified manually by experts.
