There are multiple different ways to define data quality. This project sees data quality as the '''degree to which data fulfills requirements''' based on the definition of quality by ISO 8000-102:2009 and IS0 9000:2005. Furthermore, we see data quality as a '''multiple perspective phenomenon'''. Hence, data requirements may not only be stated by data consumers, but also by data providers, administrators, legal authorities, and many other stakeholders. | There are multiple different ways to define data quality.

Welcome to SemWebQuality Wiki
This website is intended to provide information and tools for the quality of Semantic Web data.
What is Data Quality?
There are multiple different ways to define data quality. This project sees data quality as the degree to which data fulfills requirements based on the definition of quality by ISO 8000-102:2009 and IS0 9000:2005. Furthermore, we see data quality as a multiple perspective phenomenon. Hence, data requirements may not only be stated by data consumers, but also by data providers, administrators, legal authorities, and many other stakeholders.
Objects of Information Quality Perception
The quality of information is usually perceived by accessing multiple layers within an information system. Thus, judgements about information quality should always account for the elements used to retrieve the information, namely
- Hardware, e.g. the used computer
- Application, e.g. the query software
- Schema / Ontology, i.e. the structure in which the data is stored
- Data itself
