Verification and Validation of Semantic Annotations
This addresses the need for reliable semantic data in web applications, but appears incremental as it builds on existing schema.org standards.
The paper tackles the problem of ensuring the quality of semantic annotations extracted from websites by verifying them against schema.org vocabulary and domain-specific constraints, and validating them against actual web page content to detect errors and inconsistencies.
In this paper, we propose a framework to perform verification and validation of semantically annotated data. The annotations, extracted from websites, are verified against the schema.org vocabulary and Domain Specifications to ensure the syntactic correctness and completeness of the annotations. The Domain Specifications allow checking the compliance of annotations against corresponding domain-specific constraints. The validation mechanism will detect errors and inconsistencies between the content of the analyzed schema.org annotations and the content of the web pages where the annotations were found.
