A formal approach for customization of schema.org based on SHACL

TL;DR

This paper introduces a formal method using SHACL to customize schema.org vocabularies, enabling domain-specific semantic annotations for improved data quality and relevance.

Contribution

It presents a novel domain specification process that generates tailored schema.org patterns via SHACL operators, aiding domain-specific knowledge generation.

Findings

Successfully applied in tourism domain use cases

Generated domain-specific patterns for improved annotation

Enhanced knowledge assessment processes

Abstract

Schema.org is a widely adopted vocabulary for semantic annotation of content and data. However, its generic nature makes it complicated for data publishers to pick right types and properties for a specific domain and task. In this paper we propose a formal approach, a domain specification process that generates domain specific patterns by applying operators implemented in SHACL to the schema.org vocabulary. These patterns can support knowledge generation and assessment processes for specific domains and tasks. We demonstrated our approach with use cases in tourism domain.
