- Datafication is the process of replacing textual information by structured data
- The structure of an ontology is determined by the system requirements of the system that generates the data
- A zettabyte is the last byte in a dataset, marking the end of the file
- The problem of data integration is that the meaning of the data is implicit, so that manual labor is needed to translate the data to some common language
- Traditional datasets are difficult to integrate because they are interpreted without paying attention to what the data mean
- Creating effective ontologies is an art and a matter of taste
Correct
